Revision history [back]

I am currently running this:

cv::filter2D(source, 
                  dest, 
                  CV_64F, 
                  kernal, 
                  cv::Point(-1,-1), 
                  0, 
                  cv::BORDER_CONSTANT);

However, I am not interested in convoluting the whole image with a kernel, I just want to run the convolution at a given point.

Is this possible?
