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 ...

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 ...

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 ...
