Morphological Edge Detection Method of Multi-structure and Multi-scale Based on Image Fusion in Wavelet Domain

To extract the edge information from images in a better way, a new morphological edge detection method of multi-structure and multi-scale based on image fusion in wavelet domain has been proposed. The new method merges the edge detected by multi-structuring elements and multi-scale elements in wavelet domain via wavelet transformation to these detected edge images. Experimental results have shown that more detail edges and texture information could be detected by the proposed method, comparing with results from most recently proposed similar edge detection algorithm.
