Edge Contour Processing的意思|示意

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。

The original gray level image was changed into the macroscopical drawing information by pre-processing, threshold selection, image bivalency, edge detection and contour extraction and segmentation.

对原始数字图像实施预处理、二值化、轮廓提取及细化等处理后，将图像信息转变成宏观图形信息。

Secondly, for the image edge detection, methods including the gradient method, the sharp-processing method, and the Hough transformation were used, and the contour tracing was also conducted.

边缘检测处理部分采用了梯度处理法、锐化处理法、哈夫变换处理法，并对图像作轮廓跟踪处理。
