Abstract: On the analysis of the multi-scale and multi-direction mathematical morphology gradient algorithm for the image edge detection,using a kind of image fusion based on the cluster analysis of self-organizing feature map neural networks,an improved vchicle image edge detection method based on the morphology gradient is given in this paper.Experiment results are obtained by applying the edge detector on a truck image,which proves to have better effect than other existing morphogy edge detectors.
