canny edge detector

基本解釋

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.
新算法提出首先採用多尺度分水嶺變換獲取運(yùn)動物躰模型，消除了傳統(tǒng)基於分水嶺變換算法存在的缺陷；
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.
針對工件的主要特征是直線和圓形的特點，在利用Canny邊緣檢測算子進(jìn)行了邊緣檢測以提取工件的邊緣特征之後，根據(jù)Hough變換原理在邊緣空間中實現(xiàn)了工件的直線及圓特征的提取。
