摘要 在图像信息提取中,为实现任意方向、任意尺度对图像进行小波分解,在各向异性小波变换中增加了衰减因子和旋转因子的新算法,运用Matlab编程实现该算法,可准确地提取图像任意方向的趋势和细节特征,是一种高效的图像特征提取算法. During the image information extraction,in order to realize the wavelet decomposed in any direction and any size,anisotropic wavelet transform is a new theory adding rotation factor and shape ratio factor based on continuous wavelet transform. It can be realized conveniently through Matlab program. Anisotropic wavelet transform can extract the trend feature and detail feature in any direction. It is a effective algorithm to extract the feature of image.
