Hi guys,

I have a simple program that does stitching and the code I've used mainly comes from here. When complied on it's own, the program runs fine but when I embed it into a Windows Form and run the same code in a background worker, I get the following error:


Edit: This is another error that accompanies it. Also caused by the line highlighted below Error 2

I have slowly worked through the code and it seems that the error is triggered when it reaches the following line:

            cv::Mat homography = cv::findHomography(framePoints, stitchedPoints, CV_RANSAC);


std::vector <cv::Point2f> stitchedPoints, framePoints; where data is from goodMatches

for (size_t i = 0; i < goodMatches.size(); i++)
            //-- Get the keypoints from the good matches

I thank you guys in advance for taking the time to read my post and in assisting me with this.

Same error with Chamfer matching sample. Has anyone made any progress?
