computeBinaryMap()

bool OpenCVForUnity.SaliencyModule.StaticSaliency.computeBinaryMap	(	Mat	_saliencyMap,
		Mat	_binaryMap )

This function perform a binary map of given saliency map. This is obtained in this way:

In a first step, to improve the definition of interest areas and facilitate identification of targets, a segmentation by clustering is performed, using K-means algorithm. Then, to gain a binary representation of clustered saliency map, since values of the map can vary according to the characteristics of frame under analysis, it is not convenient to use a fixed threshold. So, Otsu's algorithm* is used, which assumes that the image to be thresholded contains two classes of pixels or bi-modal histograms (e.g. foreground and back-ground pixels); later on, the algorithm calculates the optimal threshold separating those two classes, so that their intra-class variance is minimal.

Parameters

_saliencyMap	the saliency map obtained through one of the specialized algorithms
_binaryMap	the binary map

Dispose()
