MaxDetect

MaxDetect[image]
gives a binary image in which white pixels correspond to constant extended maxima in image.

finds extended maxima where the range of values is not greater than h.

An extended maximum is a connected set of pixels with values greater than their surroundings.

MaxDetect effectively chops maxima of height h or less and returns all remaining constant regional maxima.

MaxDetect by default treats all eight pixels surrounding a given pixel as adjacent.

The option setting CornerNeighbors->False treats only the four pixels in the coordinate directions as adjacent.

MaxDetect takes a Padding option. The default setting is Padding, corresponding to a black background.
