方向可调小波图像边缘检测，该算法的主要功能是通过小波变换将图像的边缘检测出来。图像的边缘，按像素点来看应该是灰度值突变的地方，方向可调小波边缘检测正式应用这一特性将图像的边缘提取出来-The steerable wavelet image edge detection, the main function of the algorithm is the edge of the image detected by the wavelet transform. The edge of the image, according to the pixel point of view should be gray value mutations steerable wavelet edge detection formal application of this feature extracted from the edge of the image
