Binary Threshold - a greyscale threshold level determines an edge. This particular edge method requires dark objects on a light background. The other methods do not have this requirement.
Canny Edge Detector - a well documented method which results in a single pixel edge and is able to find edges of light objects as well as dark objects. The smoothing algorithm is not currently used in conjunction with this method.
Sobel Edge Detector - a template based edge detector which approximates the gradient of the pixel corresponding to the center of the template. Sobel uses two 3x3 matrices as a template.
Kirsch Edge Detecto r - a template based edge detector which approximates the gradient of the pixel corresponding to the center of the template. Kirsch uses six 3x3 matrices as a template.
Binary Threshold Smoothed Edges - The Binary Threshold images are smoothed automatically and then their edges are found. It provides the closest outlining of the greyscale dark on light images.
