Canny Edge Detection
Description
This component finds the edges in an image using the Canny edge detection algorithm.
The Canny algorithm uses hysteresis and the Thresh1 and Thresh2 inputs define the high and low boundaries for this. They are in the range
0-255.
The Aperture is another input into the calculation. There are three options specified by an Int index, 0=3, 1=5 and 2=7. The default is 0 i.e.
and aperture of 3.
