摘要
介绍了二值图像的轮廓跟踪算法.在轮廓跟踪过程中,首先用行扫描得到轮廓起点,然后采用链码跟踪技术,跟踪其轮廓,得到一个封闭的轮廓信息,接着转向下一个轮廓,一直到所有的轮廓跟踪完毕为止.它能够实现一次扫描,得到所有的轮廓信息,且最终轮廓信息以链码序列来存储.在以后的拟合过程中,能更方便地对链码序列进行处理,得到理想的轮廓信息.
A contour tracing algorithm on binary images is introduced. In the process of contour tracing, using the line on line scanning technique the contours starting points is obtained, which is represented by the coordinate value. Using the chain code tracing technique and tracing the contour, a closed contours information is obtained, and the contour's information in the chain code lists is saved finally. Its convenience in the following smoothing process is also introduced. This algorithm could conveniently smooth the getting contours according to the getting chain code lists, and get the ideal contours information.
