Abstract This paper analyzes the limitation of traditional edge detection methods in the use of multispectral images, and proposes an edge detection technique based on spectral space analysis of local area whose average radius can be calculated. This method expands the previous concept of edge detection of the single image and, because of the transformation from the gray value to the gray vector and the consideration of multi-scale combination, can acquire satisfying results.
