Detailed Description

OpenCV Pyramids Segmentation.

Implements image segmentation by pyramids.

Parameters:

	level	Maximum level of the pyramid for the segmentation
	threshold1	Error threshold for establishing the links
	threshold2	Error threshold for for the segments clustering

The function implements image segmentation by pyramids. The pyramid builds up to the level . The links between any pixel a on level i and its candidate father pixel b on the adjacent level are established if . After the connected components are defined, they are joined into several clusters. Any two segments A and B belong to the same cluster, if . If the input image has only one channel, then . If the input image has three channels (red, green and blue), then

There may be more than one connected component per a cluster. The images src and dst should be 8-bit n-channel images or equal size.
