FFRT: A Fast Finite Ridgelet Transform for Radiative Transport
Multiscale Modeling & Simulation, 2015This paper introduces an FFT-based implementation of a fast finite ridgelet transform which we call FFRT. Inspired by recent work where it was shown that ridgelet discretizations of linear transport equations can be easily preconditioned by diagonal preconditioning, we use the FFRT for the numerical solution of such equations. Combining this FFRT-based

A vlsi architecture for finite ridgelet transform
2003 46th Midwest Symposium on Circuits and Systems, 2006This paper presents a VLSI architecture for the finite ridgelet transform (FRIT). The proposed architecture has been partitioned into two stages. First stage computes the finite Radon transform (FRAT) coefficients and the second stage computes 1-D discrete wavelet transform (DWT) coefficients.

Robust Watermarking Scheme in Finite Ridgelet Transform Domain
2008 IEEE Pacific-Asia Workshop on Computational Intelligence and Industrial Application, 2008How to select the finite ridgelet transform (FRIT) coefficients which were suitable to embed watermark data was an interesting problem. Digital watermarking algorithms in FRIT domain were accomplished by modulating the transform coefficients, which represented the most energetic direction of an image.

Efficient Blind Image Separation Using Finite Ridgelet Transform
2013 23rd International Conference on Computer Theory and Applications (ICCTA), 2013This paper deals with the problem of blind separation of digital images from noisy mixtures. It proposes the application of a blind separation algorithm on Ridgelet Transform (RT) of the mixed images, instead of performing the separation on the mixtures in the time domain.
