The Improved Algorithm of Edge Detection Based on Canny Operator

Abstract:

The traditional Canny algorithm can only seek the finite difference from horizontal and vertical directions. For the problem which exists in it, we improved the algorithm to seek the finite difference from horizontal direction, vertical direction, 45 degree direction and 135 degree direction. So the edge detection has got improvement in the effect that detail keeps, edge articulation and edge continuity, and it wiped off some false edge. The experiment has verified the validity and correctness of the improved algorithm.
