Description: 1。 Gauss is fuzzy。This step is very simple, similar to the LoG operator (Laplacian of Gaussian) for Gaussian blur, the main purpose is to remove noise。Because noise is also concentrated in high frequency signals, it is easy to be identified as pseudo edgescanny边缘检测 c语言。 Gauss blurring is used to remove noise and reduce false edge recognition。 But because the image edge information is also a high frequency signal, Gaussian blur radius selection is very important, too large radius is easy to make some weak edges can not be detected2。

calculate gradient amplitude and direction。The edges of an image can point in different directions, so the classical Canny algorithm uses four gradient operators to calculate the gradients in horizontal, vertical and diagonal directions respectively。 But usually four gradients are not used to calculate four directions respectively。Commonly used edge difference operators (such as Rober, Prewitt, Sobel) calculate the horizontal and vertical difference Gx and Gycanny边缘检测 c语言。
