trace contour

基本解释

Besides, the algorithms of edge detection, contour extraction and contour trace have been adopted in CT imaging processing.
此外，运用边缘检测、轮廓提取和轮廓跟踪等算法将CT图像进行边缘以及轮廓的处理。
Firstly, using the contour tracing algorithm to trace the manipulated contour BMP, it has attained the contour point chain recorded by Chain Code.
首先，运用轮廓追踪算法追踪经过图象处理后的轮廓位图，形成链符法记录的轮廓点列数据。
After the key parameters of edge effect were obtained, the warping edge effect of CCOS combined with the residual error trace contour path planning was corrected.
在获得影响边缘效应的关键参数后，结合残余误差等高线的路径规划，对CCOS产生的边缘效应产生的翘边现象进行修正；
