An Algorithm for Color Image Region Segmentation Based on Contour Tracing in Anticlockwise Order
Man Chen · Journal of Nanjing Polytechnic College · 2002
In this work, we put forward an algorithm for color image segmentation based on contour tracing in anticlockwise order. In the process of contour tracing, contour lines are gained by tracing in anticlockwise order and a method a backdate search which ensures the correctness of the algorithm is use for contour tracing at those pixels where other contour pixels can not be traced continuously. By analysis of the neighbouring pixels, we avoid judging those pixels that need not be compared again. Region segmentation proceeds by recursion method based on contour tracing. The extraction of contours with a certain color value directly, as one of the strongpoints of this algorithm, is very practical.
