IMAGE COMPRESSION BY USING WALSH AND FRAMELET TRANSFORM
Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ, 2019 In this paper, Framelet and Walsh transform are proposed for transformation, and then using arithmetic coding for compress an image. The goal is to achieve higher compression ratio by applying two levels Framelet transform (FLT), and then apply 2D Walsh ...

Multiallelic Walsh transforms [PDF]
, 2023 A closed formula multiallelic Walsh (or Hadamard) transform is introduced. Basic results are derived, and a statistical interpretation of some of the resulting linear forms is discussed.

Walsh functions: shape analysis and other applications [PDF]
, 1970 Due to their binary nature, the Walsh functions have considerable advantages over the traditional sinusoidal functions used in Fourier analysis when the computations are carried out by a general purpose binary digital computer.

British Educational Research Journal, EarlyView., 2023 Abstract Children's relationship with time in preschools is an under‐researched area. Young children rarely know how to measure time using a clock, but their experiences of time may contribute to understanding children's well‐being and debates about quality in preschools.

Comparison of Image Compressions: Analog Transformations
Proceedings, 2020 A comparison between the four most used transforms, the discrete Fourier transform (DFT), discrete cosine transform (DCT), the Walsh–Hadamard transform (WHT) and the Haar-wavelet transform (DWT), for the transmission of analog images, varying their ...

Arithmetic Correlations and Walsh Transforms [PDF]
IEEE Transactions on Information Theory, 2012 In this paper, the authors continue a program to find arithmetic, or “with-carry,” analogs of polynomial-based phenomena that appear in the design and analysis of cryptosystems and other branches of digital computation and communications. They construct arithmetic analogs of the Walsh-Hadamard transform and correlation functions of Boolean functions ...

Low computational complexity variable block size (VBS) partitioning for motion estimation using the Walsh Hadamard transform (WHT) [PDF]
, 2009 Variable Block Size (VBS) based motion estimation has been adapted in state of the art video coding, such as H.264/AVC, VC-1. However, a low complexity H.264/AVC encoder cannot take advantage of VBS due to its power consumption requirements.

New fast Walsh–Hadamard–Hartley transform algorithm [PDF]
, 2023 This paper presents an efficient fast Walsh–Hadamard–Hartley transform (FWHT) algorithm that incorporates the computation of the Walsh-Hadamard transform (WHT) with the discrete Hartley transform (DHT) into an orthogonal, unitary single fast transform ...
