Abstract:
In the image edge detection,the bounds of step-structure and dirac-structure are distinguished by using modular-angle-separated wavelet transform,or combining with scale-independent algorithm,thus obtaining the bounds of the step-structure.In order to filtrate the smaller point of the wavelet coefficient needs to chose threshold value of peak value used former algorithm,However,the singularity of the edge in a image is not uniform,the faintness edge will be filtered with the non-uniform of gray-scale and no...
