Blind separation of noisy images using finite Ridgelet Transform and wavelet de-noising

2013 Second International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC), 2013
This 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. Soft Wavelet thresholding denoising of the noisy mixtures is recommended in this

A new digital image watermarking based on Finite Ridgelet Transform and extraction using ICA

2011 International Conference on Emerging Trends in Electrical and Computer Technology, 2011
This paper presents a new digital image watermarking based on Ridgelet Transform (RT) and extraction using Independent Component Analysis (ICA). Ridgelet transform is a new directional multi-resolution transform and is more suitable for describing the signals with high dimensional singularities. Finite Ridgelet Transform (FRIT) is a discrete version of

Speech Watermarking Technique Using the Finite Ridgelet Transform, Discrete Wavelet Transform, and Singular Value Decomposition

2017
In this chapter, existing watermarking techniques for the speech signal and its various features are described. A new watermarking technique is composed of the finite ridgelet transform (FRT), discrete wavelet transform (DWT), and singular value decomposition (SVD).
