针对壁虎脑切片显微图像的边缘检测需要,分析几种常用算子基本原理及算法实现,用VC^++6.0工具编程实现各种算子对一幅大壁虎脑组织切片显微图像进行边缘检测。对实验结果进行分析得出结论,Canny算子检测出的边缘比一般微分算子更精确、虚假边缘少,但也可能平滑掉一些有用的边缘和细节,综合考虑比较适合该类图像的边缘检测。
In order to detect the edge of micrograph of Geckoes brain tissue slice. Basic operators which are frequently used and studied,a micrograph of Geckoes brain tissue slice edge processing by VC^++ 6.0, and the characteristics of these methods on the image edge detection are compared. The result tells that Canny operator gets more accurate edge, but at the same time,it may slip some edge and detail. Considering synthesis,Canny operator is good for this kind of picture.
