An Approach of Color Image Edge Detection Based on Triangle Similarity

For human´s vision, the edge forms where the value of color of an image changes rapidly. And the changes are so abstract that it is very difficult to quantize. In this paper, a method detecting color image edges based on triangle similarity is presented, which turn the color changes into the changes of a trianglepsilas form. It makes the abstract problem become not only quantization but also a problem shift to us that developed more perfect field. The experiment results show that the method exploits the color feature fully, raising the accuracy of edge detection and making sure the continuous of edges.
