Detailed Description

grey reconstruction of an image 2d

This algorithm is an equivalent of Binary Reconstruction 2d applied on grey scale images case.

Grey scale values of input marker image InGreyMarkImg3d are locally dilated with respect to input image InImg3d local extrema.

Extrema search type is controlled by InLocalExtremumType parameter.

The behavior of this algorithm is illustrated in case of a 1d signal by the following figures :

maxima case
minima case

Note: this algorithm is mainly used during processing of Dilate Local Extrema 2d algorithm.
