Abstract:

In view of the traditional edge detection algorithm and the peripheral edge information incomplete point positioning inaccurate problem, put forward a kind of based on quadric surface fitting of sub pixel edge detection algorithm. Using the sub pixel figure obtained by fitting, its anti-jamming is strong, position accurately and on this basis, using the improved Canny operator accurate judgement of the image edge position. The experimental results show that the algorithm not only improves the image edge information ability, and the image edge smooth, edge point positioning precision, detail information completely.
