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.

Enhancing Medical Images Security and Efficiency With Adaptive Compressed Sensing and SHA‐3 in Telemedicine

International Journal of Biomedical Imaging, Volume 2025, Issue 1, 2025.
Security issues of telemedicine‐based secure transmission of medical images find a very thin line drawn between diagnostic acceptability and cybersecurity. Partial but imperfect solutions emerge. JPEG2000 and HEVC concentrate only on compression, failing to provide any security consideration.

Improved intra mode signaling for HEVC [PDF]

2011 IEEE International Conference on Multimedia and Expo, 2011
In the current development of HEVC, compression performance improved significantly compared to H.264/AVC for both inter pictures and intra pictures. With intra compression, the main reason for this improvement is the large increase in intra prediction directions (up to 34).

Analysis of the Compressed Video with HEVC under Optical Link Transmission

Applied Computer Systems
We study the feasibility of video transmission over optical fibre to optimise bandwidth with the implementation of HEVC codec features. We use simulation (Matlab and the OptiSystem software). Different values of the CRF are used to evaluate its impact on
