| Abstract: | In this paper,the edge detecting ability of anti symmetrical biorthogonal wavelets is theoretically analyzed.Then a multiscale edge detection algorithm,which integrates edge information of different resolution levels,is proposed to obtain the highly accurate one pixel width image edges.By applying the algorithm to real world images,the effectiveness of our method is tested,which provides a fundamental basis for employing edge information to support image indexing in wavelet based compressed domain. |
