• Where can I find non-linear Calibration Example.llb?

  Hi I LV 2010 and 2012 installed with Vision Development Module 2010 and 2012. I have Example.llb of nonlinear calibration have looked everywhere but can't find it. It is supposed to be Examples\Vision\2. Functions\Calibration. I checked two other computers with LV 2010 and VDM 2010 is installed and they lack the llb as well. Can someone let me know where I can download it? Thank you! Steve

• Original location in a corrected image (using calibration data)

  Hello

  I use the tool of vision to correct the distortion in images.
  I do not use the model grid point let the software generate the calibration sheet, but rather use a set of points (which I can define precisely in the distorted image) and provide their respective coordinates 'real world '. I can then apply this correction to other images.
  So far so good.
  Now I want to superimpose two sets of images, which are distorted differently (for example, they represent the same object, but were photographed in slightly different conditions). I have
  good adjustable using the method above and the other separately, with its own separate correction, but I'm stuck there.
  Each calibration/correction is characterized by a scale factor and a coordinate of origin. I need both to be able to superimpose the two sets of images.
  I chose non-linear calibrations that preserves the area and I thought of a way to recover the scale factor by calculating the areas of all patterns square in my series of (as calculated in the original image) calibration points, taking the average, then the square root of the area average: This gives the spacing between the points equidistant in the corrected image.
  However, I can't figure out how to get the original location in the corrected image. One of my points of calibration is associated with the position (0, 0) in the real world. However, it is neither its position (in pixel unit) in the original image or the corrected image. I need the latter. How can I get it simply (I can think of sophisticated ways to get it, but I suspect that it might be a trivial).

  Thanks in advance for your answer.
  Sincerely,
  X.

  Hello

  I guess you are referring to "Convert to/from the real world" screws. As far as I understand well as do these screws, they refer only to two "spaces". One is the distorted image of origin (with coordinates in pixels) and the other is the ideal 'real world' space, where this image was generated, with coordinates expressed in all the units you choose. I am concerned about a 'third space', the corrected image generated by the Vi "IMAQ Image of calibrated" correct, and I want to know the point, which, in the real world, has the coordinates (0, 0), where in this picture (if possible with coordinates in fractional pixels, coordinated whole pixels not only).

  I haven't posted my response to Nate, but basically we agreed that what I wanted was not available yet. I have work to do to get this information (as I suspected). It's a shame, because the Vi above obviously knows how to calculate what I'm looking for, because it maps the pixel (or fractional pixel coordinates) where the origin is located in the real world, on an another coordinate (fractional) pixel in the corrected image.

  This may be available in a future release, but for now, some work is needed here...

• U2713H / white point Calibration Software Dell precision

  System: Windows 8 x 64

  Calibration equipment: i1Display Pro

  Hardware calibration: Calibration Dell - 1.0.0 software 1.0.1 1.5.1

  Calibration of the software: Argyll v1.6.2, dispcalGUI v1.5.3.1 (spectral correction matrix)

  Monitor: U2713H

  I tried to calibrate them and profile my system with the above settings. The question is: Why am I not able to precisely define a D65 whitepoint using domain controllers for the calibration of the equipment? Each software version Dell lead a difference of temperature of about 100 KB (average) each time. This translates into a cold shade on my monitor. I tried two predefined calibration options and customized in the software in three areas of color (sRGB, aRGB and native). The values used are D65, 120 cd/m ^ 2, gamma of 2.2. I tried the XML hack so for 1.0.0 but 1.0.1 and (at least) 1.5.1 should include as a default?

  Here is a report of one of the dispcalGUI ARGB tracks:

  https://DL.dropboxusercontent.com/u/20428915/hardware_aRGB.html

  Instead, calibration software in dispcalGUI is more or less on the spot. This is a report for the native color space:

  https://DL.dropboxusercontent.com/u/20428915/software_native.html

  Can someone shed light on this issue? Is my workflow calibration flawed or HW software Dell just this wrong? Changing white point is clearly visible and completely unacceptable. Also, I wonder why the dispcalGUI assume 6600K white point in reports?

  I did ' t need XML hack in DA 1.5: before calibration under the icon display and serial No. There is a text with applied BDU, RG_phosphor.

  Measure right after seeing the ArgyllCMS reports and cost of DEVELOPMENT. Look at the white point of profile (see additional statistics). So the problem is that DA is calibrated WRONG, but it measures right. Calibration is just against the profile, but the WP profile (and measured) is not very close to the curve of daylight. It is proposed to green in a plot of xyY (0,310, 0.33 x), a D65 moved to the Greens

  ArgyllCMS working properly assuming a 6600 K D whitepoint to evaluate WP measured. Color temperature is not as important as many people think. It is more important than the white point is if it is in the light curve. ArgyllCMS choose as "asumed WP daylight" closest point in the curve of daylight to WP measured. It is very close to the curve of daylight it is very dificult for the eyes to notice of 6600-6400 K

  Subject of your problem. I think there are two ways to do this kind of bad calibration:

  1 - may be you have some color improvements active GPU. Search for "digital vibrance" in nvidia Control Panel, set it to 0%, the look of the similar things FRO in ATI Catalyst Control Center. I have suffered from this problem with 1.0.0.0 and my old nvidia GPU. Then she re - calibrate with the DA.

  2 - there are a few flaws not fixed with 1.5:

  One is that there is need MORE calbration patches to measure native gamma. No response from Dell

  Another is the luminance in fixed after writing the values of LUT3D. Change the contrast of luminance or changes of WP. Backlight LED - GB is more or less predictable. Dell/Xrite must patch its software, first of all make an aproximation + 50 cd for desured luminance, then put WP desired with LUT3D and the last to refine luminance/lower luminance in measures very tine. Of couse, it would be preferable to have an iterative process, but I doubt that this will never happen with Dell or Xrite.
  For GB-LEDs: more brightness OSD rises, the colours blue and Red occur. More contrast OSD triggers more green hue is displayed on the screen.
  It seems you case (you have more green WP coordinates as you want). You can try this:
  -Place you CAL1/CAL2 OSD
  -Open DisplaclGUI, "calibrate button" with D65 target, start measuring WP with the three RGB bars. You're not calibrate, it's just to measure WP.
  -Open OSD, brightness & contrast. Try to decrease the contrast by no 1, to be careful of in DispcalGUI measuremet window. Please note that this will lower the luminance to 110-115cd, but if it fixes WP I think it is aceptable.

• Calibration of monitor and printer

  My monitor and my printers need calibration. There are differences between such images that displayed on the display of the camera and the monitor and the monitor and printers. I seeks to determine the Colormunki and Spyder Studio solutions, but cannot find any current advice on the merits of each of these solutions. Does anyone have current experience? My system includes a Nikon D7000, an Acer monitor and printers Canon Pro9000 Mark II, MG6200, and MX920.

  Thanks for any thoughts.

  Reduce the number of variables. First of all the scorn the LCD of the camera, which is not yet remotely reliable as a guide to anything. And it could be that the display is where you should really spend your money first. What model? At the very least, there should be a panel IPS-type; If it's a slab TN, he has narrow angles and poor color accuracy in general. A good photographic use monitor will be around $500 and up, depending on the size.

  Anyway: calibrate the screen and set the objectives to give a Visual match to the printed output. Set the temperature and the luminance of the white point so white monitor is a match Visual white paper under your specific display requirements. Then set point range black/contrast, if software has this option. Glossy paper is normally in the order of 250: 1.

  Accurate color reproduction is actually not as important but to rethink the General brightness and contrast. Neutral color balance will be the same as the white point chromaticity and the display profile allows you to compensate for the specific screen response and irregularities. These things will be put in place by themselves. The critical point is to get the targeting for your work environment.

  Canon pro9000 resembles a great printer, use it as a guide - but make sure you have the correct printer profiles loaded, for the paper tray you are using. I don't bother with calibration of printer, get the first right screen calibration.

  That said, between the ColorMunki Photo and the studio of Spyder, I'd go for the first, simply because x-rite make sensors more reliable and consistent.

• Saturation disappeared, why?

  I edit and export my photos. I open them in a photo viewing program and looks like they're supposed to. But when I post them on the internet or e-mailed a lot of saturation/color disappeared. Why is this and how can I solve this problem?

  This must be a bad monitor profile. Background image in Lightroom is supposed to be dead neutral grey - and BTW, this isn't "desaturation", it is drastically changed color.

  Different applications are often affected differently by broken profiles, even when they are all the color management and must use the profile in the same way. This is because the source of images profiles are different and therefore the respective conversions in different profile monitor.

  Go to control panel > color management and replace your profile with sRGB IEC61966 - 2.1:

  

  Relaunch Lightroom when done so it can load the new profile at startup.

  This is a temporary measure and diagnosis, and the real challenge is to use a standard (colorimeter) to create a new profile. But if you don't have one, sRGB is often close enough. Unless your monitor is a model of the range wide (for Asus who would be PA249/279) - in which case you could use Adobe RGB, but to get right a calibrator is really necessary.

  If this does not help, uncheck the box "Use Graphics Processor" in Lr preferences.

• Straing gauges - calibration for measurements

  Hello

  At first, I'm sorry for my English, I'm Polish and I do what I can

  I t prepare strain measure simple application on cylindrical tube. Has created this task to MAX and now I have a problem during calibration. Performed shunt calibration.

  The main idea of my program:

  After clicking on "run" arrow in the upper-left, I will send to the tab named "calibration"(default tab) (it can also be cluster tab instead, is not serious). "." Then I load sample tested with, for ex. 1000N and the program of calculate the coefficient between the force (1000N) and the real value of NOR-9237 (configured as analog input - bridge to the MAX). Then I move to the next tab, described as '' measure '' when I perform a simple measurement with strain vs.time graph.

  I have established that the dependence is linear, so I have to use y = ax + b formula. Assuming that 'b' 0, I have to find 'a' - how can I calculate and how can I keep it for use in the next tab, 'measure '? I have no idea...

  I attach no examples of my program, because there is nothing difficult yet - DAQ Assistant and graphic waveform...

  DAQmx provides a way to create "Ladders", but also "Tasks" a linear scale is easy to assign to a channel in a task.

  I'm in the middle of an upgrade from LabVIEW today so, Kudos to anyone who publishes the screenshots I can't get right now.

• Appearance of color in Photoshop after calibration and Photoshop

  I bought a cheap monitor some time ago that claims to produce the range of Adobe RGB colors, NEC PA271W. I also bought a Display Pro X-rite i1, with software, colorimeter to calibrate my monitor.

  After calibration, the images appear right when displayed in Photoshop and print these images right on my professional printer with professional profiles, but these images appear incorrect outside Photoshop, when appears on my calibrated monitor. They appear too saturated and contrasty.

  When I check what profile is listed under the my screen color management tab, the default profile is the same as that among all the other profiles under Windows/system32/spool/drivers/color.

  What happens, I wonder. My video card is not compatible with the X-rite calibration process? The video card is the AMD Radeon HD series 7700.

  Any help would be appreciated.

  someone correct me if I'm wrong.

  I'm sorry, but you're wrong. This isn't how it works. You seem to confuse the calibration and profiling.

  Calibration is simple and linear response of the monitor correction. It affects all across the world. It is not part of the chain of color management, simply an adjustment of native behavior of the device.

  A monitor profile is a very detailed description of the monitor calibrated State. The profile is only used by applications that are color management. The operating system uses any profile, it makes only available for applications. The profile is loaded from the application at startup.

  The color managed application performs conversion of standard profile from source to monitor profile and sends the changed values to the monitor. Applications that are not color managed to ignore the profile and send straight numbers through unchanged.

  Normally, there is no reason to change anything in the title of the Windows color management, except that the profile is set as default.

• How to open with the calibration of flat technique in 7.0

  "In earlier versions, Camera Raw gave an option to set 'Blacks' = 'Brightness' = contrast ' = '0' and define a straight tone curve.  With the color space Adobe RGB value, opens with EXACTLY calibrated power of 2.2.  This gives a very flat looking for images with no "S" curve that nobody would use for beauty, but when it is used for SCIENTIFIC applications, I can raise the power 2.2th 16-bit image in Photoshop and have EXACTLY linear correspondence between the number of photons and the number of pixels.  This allows me to add photons, so divide the images to normalize, to make accurate measurements of pixel by pixel, and a lot of things we scientists like strangers to make beautiful pictures.

  Camera Raw 7.0 changed the sliders, and after hours of scientific experimentation, I can't find a combination that opens the images that are technically exactly flat (gamma 2.2, of course) without deviations from the curve to the right.

  I do weddings occasionally, science for the most part, and Photoshop is my go - to for both tool.  Thanks in advance for your help to advance the cause of science.

  Is it true if you choose the PV2010 development process?  I thought that was supposed to be always the same as what it was before.

  

  Nothing says that you MUST use PV2012 to develop your scientific images.  You can set the development process in the Camera Raw defaults or create a preset.

• Is there any function of linear programming in numbers version 3.6.2?

  I know there is no function of linear programming in numbers until 2011 (read all the old posts). I want to know is there any moment or Apple is still quite complacent to do something. In my class, I introduce spreadsheets and I choose to submit in numbers instead of excel, now I can't change my choice if I have to then I have to take excel classes and change all my previous worksheets which is equivalent to a failed in the class and object of repetition. I'm the only one facing this problem because I am the misfortunate, who made a mistake to love Mac. And in if he makes Apple feel better hear it "I manually fix (just had to learn any other way) linear programming models and then draw, while windows users use the built-in, they. Thank you Apple

  If you try to get the settings for a better line did I suggest to use linest() function:

  

  LINEST() is a function of linear estimation.  I suggest that spend you some time to familiarize yourself with the functions that offers numbers by typing the equal sign in any cell, and then looking through the list of functions on the right.

  To use the line eating function do something as show above, enter the data X and Y in the columns, as shown.  To get the slope (m in my example), select cell E2 and enter the formula:

  INDEX (LINEST (B2:B11, a2:a11, false, Nonzero-y-Intercept), 0)

  shortcut for this is:

  E2 = index (LINEST (B2:B11, a2:a11, Nonzero-y-Intercept, true), 0)

  to get the y:

  E3INDEX (LINEST (B2:B11, a2:a11, false, Nonzero-y-Intercept), 1).

  There are additional stats in the table linest() returns.  Read about it in the built-in help

  I hope this helps

• If I do not charge my laptop right when I get it, is what destroyed the battery?

  My friend had recently got a new MacBook Pro (early 2015) 13 "and it does not load right when he got: but rather let die down and then accused, but he now tells me that it has damaged its battery when I don't see much of a difference compared to my computer. (MacBook Air 11 '' beginning 2015) I found it went down by 1% every 5 minutes and go down 1% every 6 minutes. It would be great if someone could tell me if it's just a myth that I shouldn't trust or if he really did something wrong, and what to do about it. Thank you.

  Depleting layer completely the charge and recharge to full load, is what is called the battery calibration.

  New type of batteries installed in new models of Mac Laptops don't need calibration.

  Impoverishing the layer one or twice the charge wouldn't harm to the battery.

  But please do not repeat this.

  Depleting the load completely can have an effect on the battery life.

  There may be other reasons why the Mac has the problem you describe.

• HP Designjet T3500 printer: Printer - scanner calibration target T3500 is not accepted

  We need to calibrate the Analyzer (rolls and glasses are empty) our T3500 printer, but the calibration target is not accepted (calibration target is not valid), we tried in user (maintaining the image quality) and also in service (service utilities - validation scan) mode, but in both cases, the target of calibration is rejected. Same calibration target has been used for calibration of the T2300 scanner without problem.

  T3500 has the latest fw. installed.

  Please advice if you have experience with this problem, thank you.

  Hello

  Finally, the problem is solved by the black pencil..., there is a box of identification (such as a bar code) on the upper right corner of the calibration sheet, even if it has been used to sentence, but some places on this label were dead black and we have improved in pen and now the target is accepted and calibration is successfully completed.

  Thanks for your time and your suggestions.

• End of 2015 iMac 5K Calibration of the retina

  Hello. I have an iMac end of 2015 with the retina from 5K to the address 27. I do a lot of photography and want to calibrate the screen. Unfortunately, the calibration in the system preferences window gives me no option to set the display, other than the white point and the brightness. No point buying a third device of calibration of the party if I can't make actual adjustments to the screen.

  Am I missing something here? Or is it pretty well "our color is the right color" Apple? It seems to me that I had more control on other views of Mac in the past...

• NB550D - battery icon does not always reflect the right balance of time

  I recently bought a NB550D and I must say that, first of all, I am very happy with it. It tends to be a bit slow, but I can live with that.

  However, my problem is that the battery icon may not always reflect the right balance of time. After a full charge, it can present 9 remaining hours but after a stop and restart it will be may show 75% and the remaining 3 hours. If I stop and restart it can show 75% and remaining 6 hours

  When I started the unit I enabled him to discharge completely (by means of) three times, as suggested by the seller in the store, but quite frankly it seems not a fall of difference!

  Any advice will be appreciated.

  Concerning

  Hello

  Like Tom, battery depands of working time on the use of the laptop.
  Battery time can always change.

  In addition, I would recommend calibrating the battery to ensure best performance.
  You must charge the battery until the led would turn to green (blue) and should unload completely the battery until the cell stops automatically.
  This process must be repeated several times.
