canny edge detector

常见例句

In the algorithm, firstly Canny edge detector was adopted for the image boundary generation, and multi-scale watershed transform was used to initialize contour of the objects.
新算法提出首先采用多尺度分水岭变换获取运动物体模型，消除了传统基于分水岭变换算法存在的缺陷；
Because the characters of workpiece are mainly linear and circinal , Hough transform is adopted to gain the line and circle of workpiece in edge space which is detected by Canny edge detector.
针对工件的主要特征是直线和圆形的特点，在利用Canny边缘检测算子进行了边缘检测以提取工件的边缘特征之后，根据Hough变换原理在边缘空间中实现了工件的直线及圆特征的提取。
