I am new to image processing and related areas. I am trying to figure out how to chose structuring element (strel) for Morphological operations? For eg: I want to dilate a binary image in Matlab but I am not sure which strel to chose. That's proving to be really difficult since which is used when isn't clear to me. I am basically procssing large number of video frames and the algorithm demands dilation of each after binarization.
I advise you using SE = strel('disk', R, N); R depends on your image size and your purpose and N is the neighbourhood, usually 4 or 8. But experimenting with different strel elements is not difficult, you can try all and decide the best for yourself
