I need to find the regional maxima of an image to obtain foreground markers for watershed segmentation. I see in matlab use the function imregionalmax(). As I don't have the matlab software, I use the function scipy.ndimage.filters.maximum_filter() instead. However, the results from imregionalmax() and scipy.ndimage.filters.maximum_filter() are different.

Please help me how to find out the regional maxima of an image. Thanks very much for your help.

It appears as if scipy's maximum_filter returns the actual local max values, while Matlab's imregionalmax returns a mask with the locations of the local maxima.
I would expect

 lm = scipy.ndimage.filters.maximum_filter( img, ... )msk = (img == lm) #// convert local max values to binary mask

should give you similar results to Matlab's.
