Does anybody has a simple example of how to perform a 2d separable convolution with an nxn filter.
I do not understand welll how IPP works.
Is it better to add the border to the image and then to use FilterRow and FilterColumnone after the other with the entire image as ROI, or calculate the border on fly using ippiFilterRowBorderPipeline? In the last case how can I deal with the top and bottom border since ippiFilterColumnPipeline does not include the on fly calculation of the borders.
I thinck I miss something, I have studied the example at the end of the section in the documentation, but that one is limitated by using a 3x3 kernel.
