The lifting scheme offers a refined approach to implementing the Discrete Wavelet Transform (DWT) by decomposing traditional convolution-based filtering into a succession of simple, in-place ...

Abstract: The filter bank implementation of standard Discrete Wavelet Transform (DWT) suffers from coefficient expansion problem. In this paper a methodology is proposed to address the coefficient ...

📌 Overview This project implements a chaos-based encryption technique combined with the Discrete Haar Wavelet Transform (DHWT) to securely encrypt an image and overlay it with another image. The ...

The Discrete Wavelet Transform (DWT) has gained the reputation of being a very effective signal analysis tool for many practical applications. This paper presents an approach towards VLSI ...

Abstract: Single image super-resolution generation is a computer vision task that aims to enhance the detail and quality of a low-resolution image, generating a higher-resolution version. To date, ...

We present a method of data reduction using a wavelet transform in discriminant analysis when the number of variables is much greater than the number of observations. The method is illustrated with a ...

This repository contains an implementation of an image denoising technique using Multi-level Wavelet Convolutional Neural Networks (MWCNN). The goal is to improve the quality of noisy images by ...

This paper is an expository survey of results on integral representations and discrete sum expansions of functions in L 2 (R) in terms of coherent states. Two types of coherent states are considered: ...
