The image is not large enough for operation

Hi,
           I've got a problem is the same as the other people. But I'm a beginner for LabVIEW, don't be mind. Smiley Tongue Actually my program is to create a new template for tracking object. Firstly we must have a template for the object. And then the camera is moving forward the image size is changed. Here my point is to capture the object with ROI and create another template which is inside the ROI. The following attached file is the half way of my program.

Dear Michaelmexes,

Muks is talking about the IMAQ ExtractSingleColorPlane right after the IMAQ USB Snap (the one you circled in purple). Also, if you need additional help, could you also attach the pattern matching VI that you are using?

I am still not quite clear as to what your specific problem is with the VI. Are you getting errors? If not, what specific part of the code are you having problems with?

Let me know, I'll try to help!

Hi nate,
             Let me explain what i understand. If you can note from his diagram,He has given the ouptut of extract single color plane to imaq mask vi.Please note that the mask has been created from vision assistant.The mask will not have any imaq dst.My guess was since he has not properly directed the imaq dst there might be a problem.

The error he is getting is "Image not large enough for the operation" Which is a typical error which we used to get if we use mask,extract image,extract plane without properly defining the buffer.

Also i noted that he is giving +/- 45 degree search angle.I dont know why.
