Abstract

We propose a novel image denoising strategy based on an enhanced sparse representation in transform domain. The enhancement of the sparsity is achieved by grouping similar 2-D image fragments (e.g., blocks) into 3-D data arrays which we call groups. Collaborative filtering is a special procedure developed to deal with these 3-D groups. We realize it using the three successive steps: 3-D transformation of a group, shrinkage of the transform spectrum, and inverse 3-D transformation. The result is a 3-D estimate that co ....etc

A PIPELINE FAST FOURIER TRANSFORM FOR DIGITAL SPECTRUM ANALYSIS

Abstract:- This paper describes a novel structure for a hardwired fast Fourier transform (FFT) signal processor that promises to permit digital spectrum analysis to achieve throughput rates consistent with extremely wide-band radars. The technique is based on the use of serial storage for data and intermediate results and multiple arithmetic units each of which carries out a sparse Fourier transform. Details of the system are described for data sample sizes that are binary multi ....etc

wavelet based contourlet transform and its application to image coding ppt

In this paper, we first propose a new family of geometrical image transforms that decompose images both radially and angularly. Our construction comprises two stages of filter banks that are non-redundant and perfect reconstruction and therefore lead to an overall non-redundant and perfect reconstruction transform. Using the wavelet transform as the first stage, we apply directional filter banks to the wavelet coefficients in such a way to maintain the anisotropy scali ....etc

Hi, My name is Gugulethu Mabuza a student in South Africa, I need help with understanding how to use contourlet transform to normalize an iris image.
I have installed the toolbox but it is failing to run the demos, therefore I do not really know how it works. I am still downloading the compilers needed to make this toolbox functional. I was however wondering if I can get a matlab code for contourlet transform to try in the mean time.

Thanking you in advance ....etc

Deblocking of Block Transform Compressed Images Using Weighted Sums of Symmetrically Aligned Pixels (Java)
IEE Transactions on Image Processing, Vol. 14,

Abstract:
A new class of related algorithms for deblocking block-transform compressed images and video sequences is proposed in this paper. The algorithms apply weighted sums on pixel quartets, which are symmetrically aligned with respect to block boundaries. The basic weights, which are aimed at very low bit-rate images, are obtained from a two-dimensional function which obeys pr ....etc

texture segmentation with wavelet transform in matlab

Abstract

The present work deals with image segmentation which results in the subdivision of an image into its constituent regions or objects. The result of image segmentation is a set of segments that collectively cover the entire image or a set of contours extracted from the image. Each of the pixels in a region are similar with respect to some characteristic or computed property, such as color, intensity or texture. Specifically this project deals with texture segmentation of an image to ....etc
