hadamard transform in digital image processing in matlab

The Hadamard transform and the Haar transform, to be considered in the next section, share a significant computational advantage over the previously considered DFT, DCT, and DST transforms. Their unitary matrices consist of and the transforms are computed via additions and subtractions only, with no multiplications being involved. Hence, for processors for which multiplication is a time-consuming operation a sustained saving is obtained.

The Hadamard unitary matrix of order n is the ma ....etc

Abstract

Recently, Cand es and Donoho (1999) introduced the curvelet transform, a new multiscale representation suited for objects which are smooth away from discontinuities across curves. Their proposal was intended for functions f defined on the continuum plane R2. In this paper, we consider the problem of realizing this transform for digital data.We describe a strategy for computing a digital curvelet transform, we describe a software environment, Curvelet256, implementing this strategy in the case of 256 256 images, and we describe some e ....etc

FAST HADAMARD TRANSFORMS

Abstract:- The Hadamard transform (also known as the Walsh-Hadamard transform, Hadamard-Rademacher-Walsh transform, Walsh transform, or Walsh-Fourier transform) is an example of a generalized class of Fourier transforms. The Hadamard transform can be regarded as being built out of size-2 discrete Fourier transforms (DFTs), and is in fact equivalent to a multidimensional DFT of size. It decomposes an arbitrary input vector into a superposition of Walsh functions. ....etc

False color (or false colour) refers to a group of color rendering methods used to display images in color which were recorded in the visible or non-visible parts of the electromagnetic spectrum. A false-color image is an image that depicts an object in colors that differ from those a photograph (a true-color image) would show.In addition, variants of false color such as pseudocolor (see discussion), density slicing (see discussion), and choropleths (see discussion) are used for information visualization of either data gathered by a single gr ....etc
