Research output: Chapter in Book/Report/Conference proceedingConference contribution


A finite implementation of the ridgelet transform is presented. The transform is invertible, non-redundant and achieved via fast algorithms. Furthermore we show that this transform is orthogonal hence it allows one to use non-linear approximations for the representations of images. Numerical results on different test images are shown. Those results conform with the theory of the ridgelet transform in the continuous domain - the obtained representation can represent efficiently images with linear singularities. Thus it indicates the potential of the proposed system as a new transform for coding of images.
