A new quantum multi-image compression and encryption algorithm combining quantum discrete cosine transform with 4D hyper-chaotic Henon map is proposed. The four original images are firstly transformed ...
Abstract: Previous speech enhancement methods focus on estimating the short-time spectrum of speech signals due to its short-term stability. However, these methods often only estimate the clean ...
This repository contains the MATLAB code that can fast compute Discrete Cosine Transform (DCT) I-IV under matrix factorization. We consider the orthogonal DCT I-IV in ...
Abstract: This paper analyzes three signal transforms in analog domain (i) Discrete Cosine Transform (DCT), (ii) Discrete Hadamard Transform (DHT), and (iii) Haar Transform for their effectiveness in ...
This Node module is an implementation of the two-dimensional Discrete Cosine Transform (2D-DCT), and its inverse, from its very definition. It is intended for educational and research purposes. You ...
