Detailed Description

Performs search in a given direction(normal) for a given distance(pixels) for a given 'site'. Gives the most likely site given the probability from an ME mask.

• Bug fix: rewrote application of masks to use the temporal information instead of applying both temporal masks to the same image. ie: spatial -> spatio/temporal
• Added new tracking function to choose the most similar edge amongst all edges found.
• sample step.

Parameters

[in]	I	: Input image.
[in]	me	: Pointer to the moving-edges settings.
[in]	test_contrast	: When true tracking is based on contrast. The retained moving-edge is the one with similar contrast. When false, the tracking is based on the likelihood. The retained moving-edge is the one with the maximum likelihood.

		std::vector< vpMeSite > &	outputHypotheses,
		const unsigned	numCandidates
	)

Similar to the track() function, but stores the best numCandidates hypotheses in outputHypotheses. The best matching hypotheses (if it is not suppressed) is assigned to this and is stored as the first element of outputHypotheses. The hypotheses are sorted from best to worst match in the vector. A match may be in the vector but mark as suppressed. If this is undesired, you should filter them afterwards.

Exceptions

If	numCandidates is superior to me.getRange() * 2 + 1.
