Research on image matting technology based on image edge detection

摘要

Traditional method of image edge detection is greatly developed, but there are still many problems, especially the problem of coordination between edge detection precision and antinoise performance. The author of this paper performed research on the image matting technology, and put forward a kind of image matting technology algorithm based on image edge detection. From the angle of image processing, this algorithm adopts Canny operator edge detection method of image matting technology based on image edge detection, so as to perform the extracting of role picture in image. It is shown by experiment result that this algorithm can effectively realize extracting of foreground target under complicated background.
