Realistic Talking Face Synthesis With Geometry-Aware Feature Transformation

Recent studies have shown remarkable success in synthesizing realistic talking faces by exploiting generative adversarial networks. However, existing methods are mostly target specific that cannot generate images of previously unseen people, and they …

Deep Video Inverse Tone Mapping

Inverse tone mapping is an important topic in High Dynamic Range technology. Recent years, deep learning based image inverse tone mapping methods have been extensively studied and perform better than classical inverse tone mapping methods. However, …

Rate control model for high dynamic range video

This paper describes a luminance based rate control (RC) model for high dynamic range (HDR) video. A novel mathematical relationship between luminance and bit allocation of a coding tree unit (CTU) is presented. By adjusting the existing RC algorithm …

Machine learning based VP9-to-HEVC video transcoding

As more and more coding standards are developed for videos with higher resolution and higher frame rates, the conversion between them is in demand. This paper focuses on the development of fast VP9-to-HEVC transcoding algorithm. Since the …

Optimized nested protection for video Region of Interest with Raptor codes

Due to the best effort feature of many existing transmission channels, video streams often suffer from inevitable transmission errors. In this paper, we propose a scheme of robust video transmission based on the state-of-the-art Raptor codes, whose …

Analysis and comparison of FEC and FEC-ARQ protection schemes based on RS and Raptor code

Four protection schemes based on RS and Raptor code as well as FEC and hybrid FEC-ARQ are analyzed and compared for erasure channels in this paper. RS code is a classic block channel code while Raptor code is a new kind of rateless code, which can …
