Regional maxima from python
Hello, Is it possible to compute the regional maxima of a grey scaled image (8bits or more) ?
thank you

You'd have to do it by hand. You make a 2D filter which you slide across the image so that each pixel becomes 0 if it is not the maximum in the neighborhood and retains its value otherwise.

there's minMaxLoc, but that's global (for the whole img or roi you apply it on)
what do you mean by 'regional' ?
There a definition in Castleman, K : http://bit.ly/13VyHL7
If you think of an image as a landscape, regional maxima yields the local tops. This not the max value of the image. I have browsing again the documentation but that morphological operator doesn't seem to be implemented.
thanks for clarifying.
and i'd think so, too - no such thing in the library
