H-maxima transform

From Wikipedia, the free encyclopedia
(Redirected from Draft:H-maxima transform)

In mathematical morphology, the h-maxima transform is a morphological operation used to filter local maxima of an image based on local contrast information. First, all local maxima are defined as connected pixels in a given neighborhood with intensity level greater than pixels outside the neighborhood. Second, all local maxima that have height lower or equal to a given threshold are suppressed. The height f of the remaining maxima is decreased by .

The h-maxima transform is defined as the reconstruction by dilation of from :
