Description: 给定一个归一化的指纹图像，算法的主要步骤如下：
**
** 1 - 将G分成大小为 w x w - (15 x 15) 的块；
**
** 2 - 计算每个象素 (i,j)的梯度 dx(i,j) 和 dy(i,j) ,
** 根据计算的需求，梯度算子可以从简单的Sobel算子到复杂的Marr-Hildreth 算子。
**
** 3 - 估算优势方向(i,j)-Given a normalized fingerprint image, the algorithm' s main steps are as follows:**** 1- The size of G into wxw- (15 x 15) blocks **** 2- calculated for each pixel (i , j) of the gradient dx (i, j) and dy (i, j),** according to the needs of computing the gradient operator can be from simple to complex Sobel operator Marr-Hildreth operator.**** 3- estimated dominant directions (i, j)

Description: This paper presents a fuzzy topology-based method to facilitate the use of larger gradient kernels. The new method effectively limits the response area around the edge and prevents neighboring objects to affect each other. Synthetic images are used to show the superior noise suppression properties and response characteristics to both step and ramp edges. Natural images are also used to assess the performance of the newly proposed topological gradient estimation qualitatively. One of the fastest methods of localizing edges in images is based on small gradient kernels, such as Sobel, Prewitt, and Roberts. Although small gradient kernels provide a fast way
