Hardware architecture for lossless image compression based on context-based modeling and arithmetic coding [PDF]

open access: yes, 2007
In this paper we present a novel hardware architecture for context-based statistical lossless image compression, as part of a dynamically reconfigurable architecture for universal lossless compression.

Backward adaptive pixel-based fast predictive motion estimation [PDF]

open access: yes, 2009
This letter presents a novel backward adaptive pixel-based fast predictive motion estimation (BAPME) scheme for lossless video compression. Unlike the widely used block-matching motion estimation techniques, this method predicts the motion on a pixel-by ...

Reversible Integer-to-Integer Wavelet Filter Design for Lossless Image Compression

open access: yesIEEE Access, 2020
In this paper, factors that influence the lossless compression efficiency of reversible integer-tointeger (ITI) wavelet filters are presented. It is observed that there is a converged region for the bitrate of the compressed subbands.

JPEG2000 Compatible Lossless Coding of Floating-Point Data

open access: yesEURASIP Journal on Image and Video Processing, 2007
Many scientific applications require that image data be stored in floating-point format due to the large dynamic range of the data. These applications pose a problem if the data needs to be compressed since modern image compression standards, such as ...

A New Perspective on Improving the Lossless Compression Efficiency for Initially Acquired Images

open access: yesIEEE Access, 2019
A new lossless compression scheme of compressing the initially-acquired continuous-intensity images with a lossy compression algorithm to obtain higher compression efficiency is proposed. Even if a lossy algorithm is employed, for decoded original images,

Accuracy analysis of lossless and lossy disparity map compression

open access: yesAin Shams Engineering Journal, 2022
In this paper, we analysed lossless and lossy compression of disparity (depth) images with low range resolution. For that goal, the well-known publicly available Middlebury dataset is used with stereo image pairs, their disparity ground truths and ...

A comparative analysis of the state-of-the-art lossless image compression techniques [PDF]

open access: yesSHS Web of Conferences, 2022
Lossless data reduction is essential for data transmission over the Internet and the storage of data in a digital device when data loss is not permitted. The application of image compression is essential for image storing, image classification, and image

Lossless Compression of Hexahedral Meshes [PDF]

open access: yesData Compression Conference (dcc 2008), 2008
Many science and engineering applications use high-resolution unstructured hexahedral meshes to model solid 3D shapes for finite element simulations. These simulations frequently dump the mesh and associated fields to disk for subsequent analysis, which involves the transfer of huge volumes of data.

Lossless Compression Schemes for ECG Signals Using Neural Network Predictors

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
This paper presents lossless compression schemes for ECG signals based on neural network predictors and entropy encoders. Decorrelation is achieved by nonlinear prediction in the first stage and encoding of the residues is done by using lossless entropy ...

On Predictive-Based Lossless Compression of Images with Higher Bit Depths [PDF]

open access: yesTelfor Journal, 2012
Due to the rapidly increasing requirements for data transmission and storage, applications for fast and efficient compression of data have a very important role. Lossless compression must be applied when data acquisition is expensive.
