摘要
采用一种基于小波包分解和数学形态学融合的边缘提取方法用于地基云图的边缘检测.首先对图像进行基于小波包分解的边缘提取,然后对图像进行数学形态学的边缘检测,最后利用图像融合技术对两幅图像进行融合得出最优边缘图像.通过Matlab软件验证和比较,表明该方法实际使用效果较好.
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.
