- W2349888219 abstract "The available image edge detection algorithm based on the spatial-domain can capture only limited directional edge in image.An improved algorithm for the image edge detection based on the directions of each directional sub-band and its gradient is proposed to overcome the disadvantages.By the algorithm,firstly,multi-scale decomposition of the image is performed with Contourlet transform.Then the edge detection of low-frequency sub-image and high-frequency sub-image are obtained.Finally,this edge diction method combines the advantages of both methods together to fuse the two edge information obtained by different methods according to certain rule.Experimental results show that the new edge detection method is effective to suppression of noise,and has advantages of high precision image edge detection." @default.
