Detailed Description

OpenCV Canny Filter.

Implements Canny algorithm for edge detection.

Parameters:

	threshold1	The first threshold
	threshold2	The second threshold
	aperture_size	Aperture parameter for Sobel operator

The function cvCanny finds the edges on the input image image and marks them in the output image edges using the Canny algorithm. The smallest of threshold1 and threshold2 is used for edge linking, the largest is used to find initial segments of strong edges.
