    Abstract:

    In the paper,the ground nephogram edge detection based on the fusion technique between wavelet package transform and mathematical morphological method was introduced.In the proposed method,the detailed steps of wavelet package transform was presented firstly,the edge should be extracted using the wavelet package transform,and then applied the mathematical morphological method to get the image edge.Finally,the best edge of the image can be achieved by the proposed fusion technique using the edges obtained by the package transform and morphological method respectively.In order to test the performance of the proposed method,the experiment was conducted,some examples were tested and compared simulated by Matlab,it can be seen that the proposed method can get better results than the traditional methods.
