Description: 1. Cell Edge Detection (1) Principle: Soble edge detection operator--- Soble differential operator is an odd size (3 × 3) of the template under the omni-directional differential operator. Soble filter processing result, the visual impression that the only differential operator out the details mentioned in the outline of a number of relatively obvious. Laplacian operator Laplacian edge detection--- with second-order differential operator referred out more details on second-order operator as early as the image details have a strong sensitivity.
