Description: As the noise points (points, a big difference with the surrounding gray points) on the edge detection to a certain extent, the effects are therefore a better edge detector is the Laplace Gaussian (LOG) operator. It is our described in Chapter 3 of the Gaussian smoothing filter and Laplacian sharpening filter combines first smooth out the noise, and then to edge detection, it would be more effective.
