摘要
文章分析了sobel算子的小波性质,借助于cascade算法的应用,将小波多尺度分辨特性与sobel算子相结合,利用尺度滤波,提出了在含噪图像中进行多尺度边缘快速提取算法,并通过实验验证了该方法的可行性。
In this paper, we analysis sobel operator in wavelet pointer. Then we got a new muhiscale edge detection way that based on the sobel operator according to the cascade algorithms. In this way, we can obtain a edge erection image from image with noise. Experimental results are given to verify the reliability of the proposed method.
