BUILT-IN MATHEMATICA SYMBOL

MaxDetect

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

MaxDetect[image, h]
finds extended maxima where the range of values is not greater than h.

MaxDetect[data, ...]
applies maxima detection to an array of data.

Details and Options Details and Options

MaxDetect[image] finds regional maxima.
An extended maximum is a connected set of pixels with values greater than their surroundings.
MaxDetect[image, h] effectively chops maxima of height h or less and returns all remaining constant regional maxima.
MaxDetect[image] is equivalent to MaxDetect[image, 0].
MaxDetect by default treats all pixels surrounding a given pixel as adjacent. A given pixel has eight adjacent pixels in 2D and 26 adjacent pixels in 3D.
The option setting CornerNeighbors->False treats only the pixels in the coordinate directions as adjacent, which would include four pixels in 2D and six pixels in 3D.
MaxDetect works with binary, grayscale, and other images.
MaxDetect works with 3D as well as 2D images, and also with data arrays of any rank.
MaxDetect takes a Padding option. The default setting is Padding->0, corresponding to a black background.
