Concerning the issue of illegal access and malicious destruction of video data during transmission and storage, a review on encryption techniques under the high efficiency video coding (HEVC) standard was conducted, starting with the HEVC standard an

Abstract The lossless coding framework of High Efficiency Video Coding (HEVC) comprises prediction and entropy coding, while omitting the transform process. However, residuals derived from prediction continue to demonstrate significant spatial redund

Recently, learning-based lossless compression methods for volumetric medical images have attracted much attention. They can achieve higher compression ratios than traditional methods, albeit at the cost of slower compression speed. Although using fie

In this paper, we propose deep video compression with hyperprior-based entropy coding, named HDVC. The proposed method is based on the deep video compression (DVC) framework that replaces traditional block-based video compression with end-to-end vide
