Lenslet Image Coding With SAIs Synthesis via 3D CNNs-Based Reinforcement Learning With a Rate Reward
IEEE Access, 2023 The deep learning-based coding schemes for lenslet images combine coding standards and view synthesis through Deep Learning (DL) models, where the compression efficiency is heavily influenced by the coding structure and quality of synthesized views.

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.

Chebyshev and Conjugate Gradient Filters for Graph Image Denoising
, 2015 In 3D image/video acquisition, different views are often captured with varying noise levels across the views. In this paper, we propose a graph-based image enhancement technique that uses a higher quality view to enhance a degraded view.

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.

Subjective assessment of visual fidelity: Comparison of forced‐choice methods
Journal of the Society for Information Display, Volume 32, Issue 10, Page 726-740, October 2024.We compared two subjective test paradigms (ISO/IEC 29170‐2 flicker, single frame non‐flicker) for evaluation of visually lossless compression in 3D images and video. Overall, the flicker paradigm was more sensitive than non‐flicker methods, but it may overestimate artifact visibility in natural conditions. The increased sensitivity of flicker detection
