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.
