提出了一种用于图像方位分析的快速方向变换方法。在离散小波变换中引入有限冗余,可以产生八个方向子带,这些方向子带是二次采样的,并且是原始图像大小的一半。所提出的变换是使用提升格式实现的,并被应用于一些图像处理任务。给出了对人工图像和真实图像的实验结果,并讨论了这种变换的优点。
A fast directional transform for use in image orientation analysis is presented. Introduction of limited redundancy into the discrete wavelet transform enables the production of eight directional subbands that are subsampled and that are half the size of the original image. The proposed transform is implemented using a lifting scheme and is applied to some image processing tasks. Experimental results are given for both artificial and real images and the advantages of the transform are discussed.
