Adaptive Parallelization Based on Frame‐Level and Tile‐Level Parallelisms for VVC Encoding
ABSTRACT To meet the growing demand for high‐efficiency video compression standards, Versatile Video Coding (VVC) has been developed as a successor to High Efficiency Video Coding (HEVC). VVC offers approximately a 50% reduction in bitrate compared to HEVC while maintaining comparable visual quality.

Object Detection-Based Video Compression
Video compression is designed to provide good subjective image quality, even at a high-compression ratio. In addition, video quality metrics have been used to show the results can maintain a high Peak Signal-to-Noise Ratio (PSNR), even at high ...

ABSTRACT Nonlinear transforms have significantly advanced learned image compression (LIC), particularly using residual blocks. This transform enhances the nonlinear expression ability and obtain compact feature representation by enlarging the receptive field, which indicates how the convolution process extracts features in a high dimensional feature ...

Latitude‐Guided Adaptive Inter‐Frame CU Partitioning for Fast Panoramic Video Encoding
This letter proposes a multi‐feature attentive convolutional neural network (MFA‐CNN)‐based fast coding unit (CU) partitioning algorithm for panoramic video inter‐coding in versatile video coding (VVC). To address coding efficiency in panoramic videos, the algorithm employs latitude‐guided adaptive partitioning threshold and dynamic quantisation ...

Image Compression Model Based on Dynamic Convolution and Vision Mamba
An end‐to‐end image compression model integrates Vision Mamba and omni‐dimensional dynamic convolution. Enhancements to the variational autoencoder‐based framework improved its global information modelling. Two models, lightweight and heavyweight, are designed to compete with the methods of recent years.

Storage‐and‐Memory‐Efficient Learned Image Compression With Quality‐Aware Hyperprior Pruning
We propose a quality‐aware hyperprior pruning method that efficiently reduces the storage and memory cost of the hyperprior module. It consists of two parts. The first part is a hyperprior pruning method, called enhanced ResRep on hyper path, which expands a channel pruning method to fundamental components in the hyperprior module of recent learned ...
