• IMAQ CREATE, image type setting

  Hello

  I'll put my f031b Pro Guppy camera pixel format.

  It seems too long I put attributes with property nodes: pixelformat as Mono 16, no matter what I put in the "IMAQ create"--->"image type", I still get output 16-bit gray scale.

  Is this correct?  What can control when I change the image type to "IMAQ Create"?

  best,

  Wen

  If the image is passed directly to the Image to get VI of IMAQdx, the type is unimportant since it is converted by the driver when it fills with data. Only the border size is relevant.

• IMAQ Cast Image error

  Hi guys!

  So I installed a program using a camera and an analysis of the image. It works fine on another computer, but during the installation of this second system, I get:

  

  The research I found: http://forums.ni.com/t5/LabVIEW/imaq-cast-image-error/m-p/3217035/highlight/true#M934230

  This suggests that it is a matter of licensing. However, I have activated the license on this computer.

  What should do?

  /Y

  Thus, it is fixed.

  It seems that I needed two NI Vision Acquisition Module AND NI Vision Development software and then enable them both to get the program running.

  Both can be installed under license with the license of the develop module.

• working with color images

  Hello

  I am stuck on this program, I can't seem to understand.

  can someone guide me in the right direction please.

  I did this program, and it is properly take a reference image and other images rotated and attract crosshair while the images are shot.

  It works.

  but when I put a COLOR image instead of the image in grayscale. It does not work. It gives me the error.

  can someone help me with this please

  I have to build the vision of this script Wizard

  

  It seems to work with grayscale images and not the COLOR PHOTOS.

  What can I do to make this work?

  I need to work with images like this and I have to call reticle around the BLACK POINT on the left corner.

  

  I also have a sample VI created vision Assistant?

• Colorization of bitmap not shown in color images

  In CS6, colorization of a bitmap image showed the color image on the screen, that the CC version will not. It is by default only show the black image. Create a PDF or print the document translated by the image of the appropriate color specified.  Has anyone else had this problem or found a fix for this?  I use a MacPro cylinder with 32 GB of memory, so I think it's a matter of GUI.  Scroll through the document or change the size of the screen sometimes briefly the appropriate color, but he quickly returns to black. Display performance setting has no effect.

  Any solution to this would be greatly appreciated.

  Bug known, discussed several times here on the forum. It has no effect on production and until the solution is in place, you can see the correct color by opting for the overprint preview.

• B & W converstion and keep the original color image?

  What is the best way to convert an original, a color in b & W image and keep the color image?

  Your original color image is never changed... Lightroom never changes the portion of the image of your original photos. So you can always go back to the color version if you want.

  One way to do is to create a virtual copy of the color image (select the image, then ctrl + apostrophe), and then convert the virtual copy to B & W, although you can also use a snapshot, or even to convert to B & W theoriginal, knowing that you can always go back to the color image.

• IMAQ FFT of a color image

  In LABVIEW 2011 is it possible to do an IMAQ FFT on a color picture? The only thing that seems to work is on the grey scale images. When I try to use a RGB color (U32), the vi-error "Invalid ImageType" FFT image.

  Any suggestions?

  Thanks in advance.

• How to create a color image optimized vectors R, G and B IMAQ?

  Hello everyone, I have the R, G and B elements of an image RGB contained in three different vectors.

  I currently use the program as an attachment to get the color in IMAQ image.

  This program works perfectly, but I want a faster program without two nested loops.

  Is there a better solution in IMAQ?

  Best regards

  Max

  

  Perhaps you prefer to run 3 x IMAQ Replace Color Plane.

  I prefer - you have the layers of color in their native table 2D U8 form - using the LabVIEW join (because of the speed and wiring less) and write the resulting 2D table of the 32 in the image.  Performance is excellent - especially when the highlighting of the execution.

  If anyone has a better implementation: I'm interested in it.

• The color of threshold IMAQ blank image

  I'm doing a base color threshold program, but the result I get is an empty image, but only when I create the display in the Panel before me. When I copy the color Thresold.vi example screen output, it can display the output of the binary image.

  What is the difference between the output of two screen? How can I make this possible without having to copy from anywhere else?

  

  Looks like you have to select the binary Palette to the display image control that you create:

  

• IMAQ flatten image for the 64-bit version of string

  Hello

  I noticed customer odd based on vision "flatten image chain" on labview 64-bit edition. In my program I use flatten image to the string (with compression to JPEG and kind of flatten Image) to compress and send data to another application. I noticed on the compressed image color missmatch. I say red (255,0,0) 32-bit RGB image and I flattened for string and then save this string as a binary JPEG using Write to vi. When I open the file of the picture is blue (0,0,255). It doesen't matter how data is written (big endian, little endian or native) the result is always the same. 32-bit edition Labview, the code worked correctly.

  I reported a bug in the NC and I'm still waiting for a solution to this problem.

  LabVIEW: labview professional development system 2010 32/64 bits (with vision development module) completely v10.0f2 lie

  Systems: labview 64 bit on windows 7 64 bit-> flatten image to string-> false color

  LabVIEW 32-bit on windows 7 64 bit-> flatten image to String-> colors OK

  LabVIEW 32-bit on windows 7 32 bit-> flatten image to String-> colors OK

  A picture of the block diagram that I used to test the conversion is attached.

  See you soon

  Hi 3DVision.

  I think I see the problem... you code looks like he expects that out of "flattening the image of the chain" will actually be a JPG file as a string, because you have chosen to use the JPG compression options. However, this is not the way that VI is intended to be used. It is simply a way to convert an image type of Vision in a string representation which can be easier to haul around (for example via the network, the user file format, etc.). It is a parallel to normal 'flatten' that can be used on any type of data from LabVIEW. The format of this string is the owner and has provisions for storing information that is specific to the Vision images that cannot be represented in the file formats normal image (overlay information, benchmarking, custom, etc. data info). If you are save the string flattened in a file and expects to open as a normal JPG file, it is unlikely to work properly. The only way that it would be guaranteed to work is if you switch to the corresponding VI "unflatten chain. I don't know why it works in 32-bit mode, but it sounds like a lucky fluke.

  For your use case, you probably want to use the VI "IMAQ write the string. This does not give a result string that is identical to the specified file format.

• in labview how can vision 2013 I extract image from plane red color color image in fromRGB?

  ...

  Okay, now I have what I consider to be an "acceptable" solution showing the R, G and B had an Image color.  He doesn't require a "pixel-by-pixel" approach that I posted yesterday, but works directly with color plans you get the RGB image splitting in his 3 grey U8 images.

  I enclose a demo project that I saved in LabVIEW 2012.  It is quite rudimentary - you provide a picture (I used the Microsoft sample pictures folder Desert.jpg) and it shows you the Image and the red, green and blue color had.  A switch allows you to view the plans of color and the scales of gray U8 (very easy), but also allows you to consider the R, G and B channels of color (a little harder to do).  In the latter case, the Image is, indeed, not the original Image, but the Image resulting from recombination R + G + B.

  For this image to 1024 x 768 pixels, decomposition and display three color plans updated to (I estimate here) 100 times per second.  When using the gray scales, it was about 20 times faster (note that color requires make first of all the gray scale, as well as each resulting image R, G and B requires 4 bytes instead of 1 byte per pixel).

  Here is the front - note that the blue channel has almost nothing except 'sky', while the reddish rocks are particularly acute in the red channel.

• ImageToArray for color image?

  I'm using Labview 8.2 and NO vision

  There is an example OR called imagetoarray that uses the ImagtoArray.vi function; in the example, the source image is a monochrome bmp image, and the only value resulting for each pixel, I suppose, must be the intensity/brightness of each pixel, huh?  but when I insert a bmp/jpg colorful in this example, I expect a message saying 'wrong type error image', but it passes through and show a unique value for each pixel too. then, which here means this value in pixels? the Intergalactic unsigned 32-bit? what each individual color?

  My second question is related to the GetColorPixelValue.vi function. I'm trying to use this function to retrieve the color value of a pixel of coordinates fixed the coordiate is pre-tuned. When I use this function to analyze the jpg image I used above, it gives an error message 'type image worng', then I tried a bmp image, it shows as "type of image worng. What is the problem with my operation? would it not capable of managing a bmp/jpg image? Anyone have a suggestion?

  Kind regards

  x

  I hope that you are facing this problem because of 'Type of Image' you create when executing "IMAQ Create".

  The example of NOR that you referred to create an 8-bit image.

  The GetColorPixelValue requires a RGB or STL image, see the help topic for this VI.

• IMAQ Vision: image not valid type

  I use the evaluation version of LabView Pro and Vision Builder to process a video taken from a Webcam from Microsoft. I try to apply a part of the function as a filter of treatment or look at a histogram as graph below but LabView always returns invalid image type.  I assume that these functions cannot process the image directly from webcam (using Vision acquisition) and may need to be converted before their transformation. However, I'm unable to do it. Please give me any suggestions or provide that I have to use the function

  

  In most cases, WebCam will deliver Image RGB (color). Even if you have turned on the WebCam in grayscale mode (then RGB components are equal). IMAQ polygon can handle the U16 only U8 I have 16 or types of SGL.

  What you can do:

  (A) use IMAQ ColorHistograph instead of the polygon IMAQ.

  or

  (B) convert your color to grayscale image (good way is to take ExtractSingleColorPlane IMAQ and set the type of intensity. Destination image must have type Grayscale U8). You will then be able to use IMAQ polygon.

• A few color images are more saturated, creating almost a neon effect. Show the same images in IE

  When you view JPEGs on a web page, I often notice that images appear too saturated, creating almost a neon effect. These images seem normal in the photo shop, and they appear normal in Internet Explorer.

  It seems to happen more with darker images.

  This may be due to a problem with the profile for your monitor screen colors or color profiles embedded in images.
