mathematical morphology Mathematical morphology (MM) is a theory and technique for the analysis and processing of geometrical structures, based on set theory, lattice theory, topology, and random functions. MM is most commonly applied to digital images, but it can be emp ...

, 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

f

lower or equal to a given threshold are suppressed. The height ''f'' of the remaining maxima is decreased by

h

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

f

from

f-h

\operatorname_h(f)=R_f^\delta(f-h)
