1．细胞边缘检测

（1）　　原理：

Soble算子边缘检测---Soble微分算子是一种奇数大小（3×3）的模板下的全方向微分算子。Soble滤波器进行处理的结果，在视觉上只能感觉到该微分算子所提取

出的细节轮廓相对明显一些。

Laplacian算子边缘检测---用Laplacian二阶微分算子所提取出的细节多，说明二阶算子早对图像细节有很强的敏感性。

-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.
