I have created an application in LabVIEW with IMAQ that utilizes the perimeter of blob objects. To do this I used the IMAQ vi �IMAQ Mask to ROI�. This worked fine and was capable of extracting perimeters of blobs in excess of 30,000 points. Now we are attempting to do the same thing with IMAQ for Measurement Studio in an application written in C++. The catch is that the �imaqMaskToROI� appears to only support 2500 points. Is this the case? Is there a solution or work around?
