Canny Edge Detector — OpenCV 2.4.9.0.

Edge detection is the name for a set of mathematical methods which aim at identifying points in a digital image at which the image brightness changes sharply or, more
The direction is rounded to one of four possible angles (namely 0, 45, 90 or 135) Non-maximum suppression is applied. This removes pixels that are not considered to
Here is an example of more transformations, doing a pyramidal downsample of an image, and performing Canny edge detection. There are a few new things in this example.
