Latitude‐Guided Adaptive Inter‐Frame CU Partitioning for Fast Panoramic Video Encoding

Electronics Letters, Volume 61, Issue 1, January/December 2025.
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 ...

Design of Efficient Perspective Affine Motion Estimation/Compensation for Versatile Video Coding (VVC) Standard [PDF]

Electronics, 2019
The fundamental motion model of the conventional block-based motion compensation in High Efficiency Video Coding (HEVC) is a translational motion model. However, in the real world, the motion of an object exists in the form of combining many kinds of motions.

Image Compression Model Based on Dynamic Convolution and Vision Mamba

IET Image Processing, Volume 19, Issue 1, January/December 2025.
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

IET Image Processing, Volume 19, Issue 1, January/December 2025.
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 ...
