What are various masks to detect edges in an image?
Here are some of the masks for edge detection. Prewitt Operator • Sobel Operator • Robinson Compass Masks • Kirsch Compass Masks • Laplacian Operator.
What is mask in edge detection?
Kirsch Compass Mask is also a derivative mask which is used for finding edges. Kirsch mask is also used for calculating edges in all the directions.
How does a mask work in image processing?
A mask is a binary image consisting of zero- and non-zero values. If a mask is applied to another binary or to a grayscale image of the same size, all pixels which are zero in the mask are set to zero in the output image. All others remain unchanged.
