pixel scan meaning in English

图素扫描
像素扫瞄
象素扫描

The principle of this approach is : during the second alphabetically pixel scanning of the labeling algorithm , the first pixel of each connected components is found , and a start - point table used for contour following is set up based on certain principles , thus the operation of search start points of the contour in the image is avoided , the execution of the standard contour following algorithm is accelerated
算法的基本原理是：利用标记过程寻找连通区域中第一个像素出现的位置，在此基础上根据一定原则确定轮廓起点，省略了在图像中逐像素搜索轮廓起点的过程，达到加速算法执行的目的。
