A Novel Rate-Control for Predictive Image Coding With Constant Quality

open access: yesIEEE Access, 2019
Predictive image coding systems yield a high-compression performance at low computational complexity, and are therefore popular in standards and prominent coding techniques for both lossless and near-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 ...

2-D Bi-Level Block Coding for Color Image Compression and Transmission With Bit-Error Awareness

open access: yesIEEE Access, 2020
In this paper, we develop a new color image lossless compression algorithm with bit-error awareness based on a general bi-level block coding method. The proposed method contains three stages.

A Reversible Data Hiding Method in Encrypted Images for Controlling Trade-Off between Hiding Capacity and Compression Efficiency

open access: yesJournal of Imaging, 2021
In this paper, we propose a new framework for reversible data hiding in encrypted images, where both the hiding capacity and lossless compression efficiency are flexibly controlled.

A Stochastic Model for Block Segmentation of Images Based on the Quadtree and the Bayes Code for It

open access: yesEntropy, 2021
In information theory, lossless compression of general data is based on an explicit assumption of a stochastic generative model on target data. However, in lossless image compression, researchers have mainly focused on the coding procedure that outputs ...

Improved Median Edge Detection (iMED) for Lossless Image Compression

open access: yesImage Analysis and Stereology, 2023
A wide variety of applications are used in lossless image compression models, especially in medical, space, and aerial imaging domains. Predictive coding improves the performance of lossless image compression, which highly relies on entropy error.
