IMAQ fully black image output local threshold

Similar Questions

• After that the threshold.vi, GRAYSCALE U8 type IMAQ image turns into a completely black image.

  I want a threshold, the image of u8 after equalize.vi, but the result is the image turns into an image.before completely black equalize.vi, i use histogram.vi and the interval is (0,0) .where is evil? I really appreciate your help.

  Unless you enter a value in the entry 'Replace the value' threshold IMAQ, your output pixel values will be 0 and 1.  In a grayscale image, you will not be able to see anything.  Try to define the 'replace' value to 255 and see if the data appears.  Here's a note from the help file on this function.

  Note  Use a binary palette when you see an image that a threshold was applied in mode replace. However, what range to use for viewing depends on the replacementvalue. For example, viewing a picture of threshold could be achieved with a palette of gray. However, in this case, please use a replacement value of 255 (white) to better see image of threshold.

• Turn the black images (not black & white or grayscale)

  I want to do black leopard fur. I have been looking for tutorials on color change, played a bit with the hue/saturation and nothing seems to work. Anyone know how to make a black image without making the whole image in black and white?

  

  Since there is no answer to your request, I thought I would take a shot at him. I started by putting the image intact on its own layer. Image > apply image of the blue channel set on multiply to build density and contrast. Follow up with a quick selection of the Lion (and Refine Edge). As shown in the Panel layers, three adjustment layers have been added to change the curves, to convert the image hidden in B & W and work with the Hue/Saturation since black lion is not a neutral black. Finally, I made a composite image for some local dodge, burn to add shadow under the lion's paw. I have not had a time that image deserved but especially to confirm the approach. It's rough in some places; highlight your separation needs work, as does the Hue/Saturation adjustment and the mask around the eyes. Sorry about that.

• Why do I get black images?

  I get sometimes black images when I open an image on Facebook and other sites. Often when I have several tabs open. I tried the following, but it did not help at all:

  -clean money
  -Make sure that the site permissions do not block the images.
  -no antivirus interferes with the browser
  -execution of Firefox in "safe mode" with all add-ons disabled
  -Reinstall Firefox

  This does not happen with other browsers. So, it seems to me that this is a bug in Firefox. I use Firefox 10 with Windows XP SP3.

  Any ideas?

  So, you still have the problem saving mode?

  Create a new profile as a test to see if your profile is the source of the problems.

  See "basic troubleshooting: a new profile:

  • https://support.Mozilla.org/KB/basic+troubleshooting#w_8-make-a-new-profile

  There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

  If this new profile works then you can transfer files from the old profile to the new profile, but make sure not to copy corrupted files.

• Satellite A660 - webcam only shows a black image

  Hey,.

  I have a satellite A660 PSAW3A-07P00R running 64-bit windows 7.
  No reason the webcam just stopped working. Whenever I y access either by the program of toshiba or others (such as Skype), I am facing a black image despite the blue camera power light is always on. The wecam application works fine and everything, it'll even take photos and videos even if he won't save them because it captures anything.

  I checked in the Manager of tasks, and despite me running on windows 7 64-bit, the program is displayed as ' TWebCamera.exe * 32 "leads me to believe that he is trying to run 32-bit...
  I reinstalled the driver for the webcam 64-bit of the toshiba site _3 times_ yet I still have the same problem (Yes, I mean 3).

  It's really frustrating me and any help would be appreciated!
  Thanks, Luke.

  Hello

  This s really strange behavior, mate

  But I can only imagine this problem is driver-related and not a hardware problem then try this:
  Remove the webcam driver and restart your computer, run CCleaner (freeware tool) to clean and fix registry problems and reboot once again. Then visit the official page of Toshiba and and download the new driver of the webcam for your model and the OS.

  Normally after the next reboot the webcam should start working with success.
  Can you confirm this? :)

• Printer HP C4680, Analyzer product black image

  Mac 10.6.  C4680 scan produces a completely black image.  Back to zero makes no difference.

  AHA!  If the copy button does not have a good copy (which is just a sweep and a combined print), then your scanner is dead.

  I'm sorry.  You can reset the printer by turning it off, remove the power cord at the back of the printer for 30 seconds, plug back in and turn it on, but I don't have much hope for it.

• Black image to develop the module during the use of acceleration GPU on Macbook Pro

  Since the update of Lightroom 6.6, I was see the "bug of the black image" to develop the module still very frequently.

  Basically, 1/3 of my photos appear black when you view in the develop module.

  If I select 'View', 'Before', the original is displayed correctly, when switching to "After" it becomes black. Even in mode split the side "Before" picture, the side is 'After' is black.

  If I play with some settings and select 'Auto' the image appears correctly again.

  If I disable GPU acceleration, then all images are displayed correctly, but I would use the GPU acceleration.

  Any ideas how to fix?

  Is there some sort of connection that I could activate that help you solve the bug?

  The issue will be probably set with 6.6.1 or 6.7 - when - knows only Adobe.

  Until then your solution is to disable the GPU acceleration or roll back to 6.5.1. Are you using a 4 k or more display? If this isn't the case, I guess you don't see no gain in performance in any case, don't you?

  Here's how: How do I roll back to Lightroom 2015.1.1 or Lightroom 6.1.1? Lightroom Queen

  Just replace 6.1.1 by 6.5.1.

• Fully scalable image

  Is it possible to put a fully scalable image in page? I mean the width is the width of the browser and the height is proportional.

• How to lighten or remove the black images or layers in Photoshop CS5?

  For several months, trying to find the best ways to reduce the excessive amount of toner that is required to print several pdf documents in black and white or in grayscale.  I use Leanprint, but can still pages of dark and black images.

  Adobe Acrobat X positions say to use Photoshop to remove black graphics and/or reduce the darkness of the images.  However, they provide no information on what to do in Photoshop.  I'm not a fool, but I know very little about Photoshop other than that, there are probably several ways to achieve this, depending on the circumstances.  I'm afraid of having to spend more hours trying to figure out which is the best option to use in each specific situation.

  It is curious that it has been so difficult to find the information needed, as many other people would like this information as well.

  I hope someone can advise me or just tell me some directions and resources as starting points.   Even knowing the best conditions of search to find this information might be useful.

  Thank you for any assistance.

  Cathy

  OK, I think I was assuming you want to create a pdf with a light images to print later version.

  When you place a pdf file in photoshop, it is rendered, therefore, the whole file/page would be editable as you would any other image.

  Take a look at adjustment layers. You will find the one that is just for the brightness/contrast. It'll do what you want and you affect all layers below, unless you hold on to the next layer.

  You can find the adjustment in the menu layers layers, and it is also located at the bottom of the layers panel. Just hover over each icon and it will tell you what they mean. Click the icon to display a menu of all the adjustment layer commands that are available.

• IMAQ Unflatten string image

  Hello

  I use the IMAQ flatten image for the vi string to flatten an acquired image and write it to the binary file. Later, when I read the binary file and try with it chain unflatten, I get an error message:

  74 error to Unflatten channel into frames get & Process.vi

  Possible reasons:

  LabVIEW: Memory data structure or corrupted.

  What I am doing wrong? I've attached screenshots to flatten and unflatten operations.

  Thank you

  Soheyl

  I actually found the problem. For future reference: I added a flatten the IMAQ Image to a string on the diagram to unflatten and wired his output to the terminal 'data type' binary file reading. May not be a more elegant solution, but it works.

• Unable to export images, solid black image file produced

• System error IMAQ using IMAQ Clipboard to Image

  Hello

  I have a VI that prints screen then use the Cliboard IMAQ to Image function to get the image into something that I can handle in LabVIEW.

  It works perfectly when I'm in the LabVIEW environment. As soon as I select any other program LabVIEW throws the below error. I don't know if it is a mistake to LabVIEW or something to do with how the window Clipboard works.

  

  Any help would be appreciated, or any other ideas of how to take a picture of what is on my computer for analysis in LabVIEW.

• IMAQ resample invalid image type

  Hello

  I'm rewriting an old non-versatile version of a VI. I don't have much experience but I have the old VI as a kind of model for what I do. It's weird, but even if I try to do things exactly the same way, they do not work.

  I acquire an image high resolution camera (IMAQ to acquire) which is too large (1280 x 1024). I want to resample (IMAQ resample) at 256x320px.

  I get the error message: error-1074396080 occurred in the type of IMAQ image resample not valid.

  The probe I put to read of the Src of the Image shows the image correctly and tells me that it is a 16-bit unsigned image. This should be a valid image type, right?

  No, not right. IMAQ resample does not support the type of U16 (at least until VDM2011). See help.

  Convert your image to I16 (if possible) before resampling.

• Train of SVM IMAQ for no Image data

  Hello

  I am fairly new to machine algorithms for learning about Labview so please be patient if my question seems stupid. I was wondering if there is a workaround to use the screw of Machine Vision SVM (e.g. IMAQ SVM Train) for not the image data. I know Machine learning package and I will surely give it a try with those but MV screws are really well organized and allow to record the training in a very elegant manner.

  Indications, suggestions or, well, even a "no, can't it' is really appreciated!

  Moreover, any luck of having the learning algorithm Machine present natively in LV?

  Thank you

  FRAX

  -According to my knowledge IMAQ screws are specifically for the Images.

  -Your best chance is using Machine learning package that you have already found.
