Detailed Description

SoCannyEdgeProcessing

This engine models the Canny edge detection workflow which is composed of the following steps: 1) Gaussian filtering
2) Gradient computation
3) Non maximum suppression in the gradient direction

The algorithm also provides estimated parameters for applying an hysteresis thresholding on the output image which represents the gradient local maxima.
