Detailed Description

Hit-or-miss Morphological Operations

In mathematical morphology, hit-or-miss transform is an operation that detects a given configuration (or pattern) in a binary image, using the morphological erosion operator and a pair of disjoint structuring elements (see CompStrElt and CompStrEltList). The result of the hit-or-miss transform is the set of positions where the first structuring element fits in the foreground of the input image, and the second structuring element misses it completely.

		const StrElt &	foreSE,
		const StrElt &	backSE,

thin() - Thinning transform

Thinnings consist in removing foreground image pixels matching a configuration given by a composite SE. In other words, the hit-or-miss transform of the image by this SE is subtracted from the original image.

Parameters

[in]	imIn	: input image
[in]	foreSE,backSE	: foreground an background structuring elements
[out]	imOut	: output image
