Efficient mode decision scheme based on edge detection with Gaussian pulse for Intra-prediction in H.264/AVC

Alexandria Engineering Journal, 2022
Advanced Video Coding (H.264/AVC) is one of the most important video coding standards which was developed by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts Group (MPEG).

Fast Intra Prediction Mode Decision based on Rough Mode Decision and Most Probable Mode in HEVC [PDF]

Journal of Broadcast Engineering, 2014
High Efficiency Video Coding (HEVC), the latest video coding standard, has twice of the compression efficiency compared to AVC/H.264 under the same image quality condition. To obtain the improved efficiency, however, it was adopted for many methods which need complicated calculation, and the time complexity of HEVC was increased more than that of AVC/H.

Fast 3D-HEVC Depth Intra Coding Based on Boundary Continuity

IEEE Access, 2021
The encoding format of the 3D extension of high efficiency video coding (3D-HEVC) consists of a multiview color texture and an associated depth map. Because of the unique characteristics of the depth map, advanced coding techniques are designed for depth

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

A novel energy reduction technique for H.264 intra mode decision

, 2011
In this paper, we propose a novel energy reduction technique for H.264 intra mode decision. The proposed technique reduces the number of additions performed by Sum of Absolute Transformed Difference based 4×4, 16×16 and 8×8 intra mode decision algorithms

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...
