Resolution of the image has changed after the calibration of the image

Hi all

I put my webcam resolution up to 1280 x 720, but after the Calibration of the Image, the video changed to 1364 x 730.

This affects at the coordinate of filtering? It is very important in my application.

BTW, Pattern Matching 4, there is an exit of matches (real world), how to give him information to translate from pixel in mm? Currently I use corresponding pixel and use a few calculations to translate correspondence in mm. And where is the origin of the actual coordinates? It is also in the upper left corner as pixel coordinates?

Hello

You can try using the "IMAQ convert Pixel to Real World VI" to transform the coordinates of the pixel to the real world coordinates.

Best regards.

Daniel.

  • Display has changed after Windows update

    After you have installed the latest updates of windows on 12/12/2012, my screen has changed. All the graphics have been expanded, including the desktop icons, taskbar, tool bars, bars of window, etc.. I checked the configuration of the monitor and the icon size in the taskbar and start menu properties (which remains set on small icons), but I can't find how to go back to my original display size.

    The installed updates were:

    Update security for Windows XP (KB2758857)

    Update security for Windows XP (KB2753842)

    Update security for Windows XP (KB2779030)

    Update of security suites for Microsoft Office 2007 (KB2760416)

    Update of security for Word Viewer (KB2760498)

    and

    5.10 Skype for Windows (KB2727727), who fails to install

    Grateful for any help please?

    Thank you for your kind assistance which directed me to the solution. Change the screen resolution in the problem resolved display settings. Strange how that changed spontaneously after the restart following the installation of the security updates.

    my start page since always yahoo, after 33 of firefox updated itself, the page quite a bit bizarre, his yahoo but not as the ordinary classic. I can't seem to go back even when I cut and paste the web address off chrome or explorer, where the yahoo page looks like classic its normal self. WHY is it be changed in mozilla firefox 33? I know in firefox 32 it is normal, when I go in chrome or Explorer, it looks good and yet not flip over in my mozilla firefox even though it uses the same adresse_web. Its driving me crazy, please tell me I'm not the only one this has happened (today 15 October, 2014) and what I can do to heal/fix and do go back to the way it was.

    HI, I understand that the start page no longer appears as before. I'd be happy to pose for a screenshot of the page so that we can investigate a bug for it, but in the meantime it may be useful to use the previous version.

  • The system time has changed after the restart of Bootcamp

    Hello

    After a restart of the boot camp partition Windows 10. I have the wrong time, in fact its always an hour later that it is.

  • Microsoft Word has changed after the installation of Service Pack 4

    When I turned on my computer this morning, I found the appearance had changed completely - the fonts, colors, the sidebar etc. However we can tweak those who use the Panel and the other adjusts the rest very easily.

    BUT now, I find that the word seems back to an earlier version - especially visible when you try to insert graphics. He seems to be back in Word 2003, where the paintings were very heavy and difficult to use and also look different when done from the charts I used in Windows Vista until yesterday. I'm in half way through a document and need to create a consistent look for the cards and it is now impossible. What should I do?
    Thanks for any help.

  • Changing the Composition resolution blurs my images.

    Hi, I would greatly appreciate any you could throw on an issue that we will have some light.

    We have some rendered images of 3DSMax to 380 x 320 pixels, and we have it as a sequence of images. We have about 150 rotations of spinning product already made to this size and these initially sitting in a flash model, so a user could turn product autour. The customer's Web site was redesigned and we must integrate these makes a model of different size, specifically 396 x 297 (which is the size of the new flash player). However, whenever we try to change the resolution of the composition of 380 x 320 396 x 297, the film seems to have been almost "fuzzy" and becomes blurred. It is not very pretty and we lose the images we made out. We do something wrong? We tried to place the pictures (380 x 320) in a composition of 720 p and it looks good, but as soon as we change the resolution to 1280 x 720 to 1280 x 719 it blurs it once again. We also tried to keep the same report that the original film but by changing just the height or just the width and the same issue occurs. Sometimes it's worse. We made sure it's too square pixels.

    I made sure that After Effects is up-to-date, and we made sure that OPENGL is off. This vagueness is not only evident in the preview, but also when we make out as a Quicktime Animation. We use After Effects 5.5 on Windows 7, but have also tried this on a Mac without result (for the hell of it).

    What happens here? Thanks in advance for any help you guys could offer, thank you. It has been the bane of my life for 2 days! I don't know that it's just my lack of understanding of the functioning of the pixels and stuff. I have read through the help documentation, but maybe I'm missing something?

    As long as your film is not resized as long as the position property is on whole pixel values there is nothing about the size of a composition that will change the sampling of pixels void (sharpness) of the sequence.

    If your film is an odd number of pixels high or wide, it will be softer in After Effects, it's in Photoshop because that AE will be zero the anchor point in the middle of the sequence and half a pixel off forcing sub pixel resampling. There is no way to avoid this except to manually reset the anchor point to a whole pixel value.

    If your film is vector art and this isn't an even number of pixels high or wide, you will have exactly the same problem that you have with rastor images, unless you set the continuously rasterize images. If set to continuous raster and vector art was created in Illustrator with nod to the set of pixels, then a line of 1 pixel (a point) in your vector image, even with the collapse of the transformations on will be rasterized in AE in a width of two pixels line because the line is not aligned with the composition pixel grid. That's a lot of difference if your work has thin horizontal or vertical lines. It's always a good idea to keep all illustrations an even number of pixels high and wide.

    If footage only looks sweet when rendering you are facing the same void pixel sampling problem when your publication is an odd number of pixels high or wide. All MPEG (including FLA) films must be an even number of pixels high and wide. This is how the compression. This is how the codec. If make you something to 295 X 333 pixels for a MPEG codec then rendering will be converted to an even number of pixels high and wide. This will soften the rendering. If it's H.264 (movies more flash are returned to the h.264 format) then you're stuck with a frame size requirements even tighter game.

    Check the anchor point of your film. If it isn't a whole pixel value, change it. Make sure it is positioned on a whole pixel value.

    Now change the size of the model at any number of pair of pixels high and wide, and the images will display exactly the same as long as your model and your film is square pixels. If your film or your composition is set to any other format of pixels then the image will soften. Can't do anything else.

  • Change the size of the resolution and the image does not change the result on the screen?


    I use Photoshop CS3. I'm changing the resolution of several images that will be printed in a newspaper. So the current images are 72 dpi and really huge - for example 36 x 27 inches (size of the document), and when I change it to 300 dpi, the size of the image to reduce to about 8 x 6 inches, as I hope. But the image I see on the screen does not change. Thus, for example, when I open the image originally, it's 33% and the entire image is visible. After I change the resolution and the size of the image has changed accordingly, the image appears to be always the same and it remains at 33%. The image should not shrink on the screen because its size has been reduced? Or if she stays the same on the screen, the percentage should not change? I mean if the size of the document is now 8 x 6, it should be able to display at 100% and not to fill my whole screen... I'm so confused. Thank you...

    Gradded,

    The "Size of the Document" of the dialog box size of the Image is just to specify the size (in inches) that your document will be printed. The ppi adjustment has nothing to do with what is displayed on your monitor. Your monitor does not care something about PPI. The monitor contains a number of pixels and after you change this setting, ppp, the monitor will always be the same number of pixels.

    As long as you leave the box "Resampling" disabled, will not change the size of your image (pixel Dimensions). You won't see any change on your monitor. If you check "Resample", then the size (in pixels) of your image will change.

    I hope this helps.

  • The screen resolution has changed.

    After that I have updated to the latest version of Muse, my screen is enlarged. It looks like the screen resolution has changed. How can I change the resolution of the screen on Muse?

    On Windows, 2014.3 Muse now supports 100%, 150% or 200% resolution, according to the scale factor you set in Control Panel. My guess is that you have your control panel set at about 125 per cent and Muse chose the scale factor supported 'closer', which is 150%. We've heard a few users that they would prefer Muse to continue functioning at 100% in this case.

    This sounds like the situation you're in?

    Now, you need to set the scale factor to your screen to 100% having muse running at 100%, but we are working on a solution in the short term to say the Muse to operate at 100% without changing your scale factor of Panel controls.

  • After that Ms last update the task manager has changed

    After that the last MS updated, the task manager has changed. I used for the right click at the bottom of the screen, select Task Manager & get 3 or 4? options to select.

    Those I used gave me a chart of the use of Internet + speed info; now, I only get the list of processes, no option & the only way out is to TAP (DO NOT TOUCH!) the ESC key.

    Is this another feature of MS or make me a form of bribery? JV

    Sorry, but I don't really know what the problem is here. In any case, try to roll back OS to an earlier time using System Restore tool. Choose the time prior to installation of update from Ms. Everything should be as it was before.
