Homogeneity-based fast CU partitioning algorithm for HEVC intra coding

Engineering Science and Technology, an International Journal, 2019
High Efficiency Video Coding (HEVC) is a new video coding standard released as a successor for H.264/AVC. It expected to reduce by 50% the bitrate for the same perceptual quality.

Machine Learning-Based Early Skip Decision for Intra Subpartition Prediction in VVC

IEEE Access, 2022
The recently published video coding standard, Versatile Video Coding (VVC/H.266), has the intra subpartition (ISP) coding mode, which divides an intra-predicted block into smaller blocks called subpartitions, each of which can be predicted using the ...

HEVC Intra Frame Coding Based on Convolutional Neural Network

IEEE Access, 2018
The HEVC standard offers high performance with a lower bitrate for intra frame coding, but still requires many bits. An alternative intra frame coding framework based on convolutional neural network (CNN) is proposed in this paper.

HEVC/H.265 Intra Coding Based on the Human Visual System

IEEE Access, 2019
High efficiency video coding (HEVC) is standard in the video compression field and performs well not only in video compression coding, but also in image compression. Regions of interest (ROIs) and just noticeable difference (JND), two human visual models,

A Genetic Approach-Based Intra Coding Algorithm for H.266/VVC

Информатика и автоматизация
This paper presents a genetic approach for optimizing intra coding in H.266/VVC. The proposed algorithm efficiently selects coding tools and Multi-Type Tree (MTT) partitions to achieve a balance between encoding time and video quality.

Attention-Based Adaptive Intra Refresh Method for Robust Video Coding

Tsinghua Science and Technology, 2012
Intra refresh is an efficient and simple technique for suppressing temporal error propagation in video transmission over error-prone networks. However, most existing intra refresh algorithms do not make good use of the visual perceptual mechanism of the ...

An Efficient LiDAR Point Cloud Map Coding Scheme Based on Segmentation and Frame-Inserting Network

Sensors, 2022
In this article, we present an efficient coding scheme for LiDAR point cloud maps. As a point cloud map consists of numerous single scans spliced together, by recording the time stamp and quaternion matrix of each scan during map building, we cast the ...

Clinical, Histopathological, and Molecular Characterization of Pediatric MN1::ZNF341‐Associated Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and

A Low Complexity Algorithm for 3D-HEVC Depth Map Intra Coding Based on MAD and ResNet

IEEE Access
As an extension of HEVC, 3D-HEVC retains the quadtree structure inherent to HEVC and is currently recognized as the most widely adopted international standard for stereoscopic video coding. In intra coding, quadtree partitioning is determined recursively
