clone
Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.
clone(): this;The this result.
computeBinaryMap
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.
