Is it possible to run filter2D at just one point in an image?
I am currently running filter2D
:
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?
