Context-adaptive Entropy Model for End-to-end Optimized Image Compression
TL;DR: In this article, a context-adaptive entropy model is proposed for image compression, which exploits two types of contexts, bit-consuming contexts and bit-free contexts, distinguished based upon whether additional bit allocation is required.

An End-to-End Joint Learning Scheme of Image Compression and Quality Enhancement with Improved Entropy Minimization
TL;DR: This paper proposes a novel joint learning scheme of image compression and quality enhancement, called JointIQ-Net, which achieves a remarkable performance improvement in coding efficiency in terms of both PSNR and MS-SSIM, compared to the previous learned image compression methods and the conventional codecs.

Context-adaptive Entropy Model for End-to-end Optimized Image Compression
TL;DR: The proposed context-adaptive entropy model exploits two types of contexts, bit-consuming contexts and bit-free contexts, distinguished based upon whether additional bit allocation is required, which allows the model to more accurately estimate the distribution of each latent representation with a more generalized form of the approximation models, which accordingly leads to an enhanced compression performance.

TL;DR: In this article, a remote forensics system based on a network is provided to allow for accessing a forensics analysis center from a remote area to perform forensic analysis, which includes one or more remote terminals performing forensic analysis on an evidence device, through a virtual forensic tool when the evidence device is connected to the remote terminals via a wide area network.
