Extended Multi WLS Method for Lossless Image Coding [PDF]

open access: yesEntropy, 2020
In this paper, the most efficient (from data compaction point of view) and current image lossless coding method is presented. Being computationally complex, the algorithm is still more time efficient than its main competitors.

Analysis of power–accuracy trade‐off in digital signal processing applications using low‐power approximate adders

open access: yesIET Computers & Digital Techniques, 2021
In recent years, approximate circuit design targeting the error‐tolerant applications has gained significance. In this study, the authors propose a metric that ranks a stand‐alone approximate adder in terms of power savings obtained for a given mean ...

Generalized PCM Coding of Images [PDF]

open access: yesIEEE Transactions on Image Processing, 2012
Pulse-code modulation (PCM) with embedded quantization allows the rate of the PCM bitstream to be reduced by simply removing a fixed number of least significant bits from each codeword. Although this source coding technique is extremely simple, it has a poor coding efficiency. In this paper, we present a generalized PCM (GPCM) algorithm for images that

Hyperspectral Pansharpening Based on Homomorphic Filtering and Weighted Tensor Matrix

open access: yesRemote Sensing, 2019
Hyperspectral pansharpening is an effective technique to obtain a high spatial resolution hyperspectral (HS) image. In this paper, a new hyperspectral pansharpening algorithm based on homomorphic filtering and weighted tensor matrix (HFWT) is proposed ...

Tree coding of bilevel images [PDF]

open access: yesIEEE Transactions on Image Processing, 1998
Presently, sequential tree coders are the best general purpose bilevel image coders and the best coders of halftoned images. The current ISO standard, Joint Bilevel Image Experts Group (JBIG), is a good example. A sequential tree coder encodes the data by feeding estimates of conditional probabilities to an arithmetic coder.

Structure Tensor-Based Algorithm for Hyperspectral and Panchromatic Images Fusion

open access: yesRemote Sensing, 2018
Restricted by technical and budget constraints, hyperspectral (HS) image which contains abundant spectral information generally has low spatial resolution. Fusion of hyperspectral and panchromatic (PAN) images can merge spectral information of the former

Time-sequential Pipelined Imaging with Wavefront Coding and Super Resolution [PDF]

open access: yes, 2017
Wavefront coding has long offered the prospect of mitigating optical aberrations and extended depth of field, but image quality and noise performance are inevitably reduced. We report on progress in the use of agile encoding and pipelined fusion of image
