AIVC: Artificial Intelligence Based Video Codec
2022 IEEE International Conference on Image Processing (ICIP), 2022 This paper introduces AIVC, an end-to-end neural video codec. It is based on two conditional autoencoders MNet and CNet, for motion compensation and coding. AIVC learns to compress videos using any coding configurations through a single end-to-end rate-distortion optimization.

Impact of Constant Rate Factor on Objective Video Quality Assessment
Advances in Electrical and Electronic Engineering, 2017 This paper deals with the impact of constant rate factor value on the objective video quality assessment using PSNR and SSIM metrics. Compression efficiency of H.264 and H.265 codecs defined by different Constant rate factor (CRF) values was tested.

Side-Information Generation for Temporally and Spatially Scalable Wyner-Ziv Codecs
EURASIP Journal on Image and Video Processing, 2009 The distributed video coding paradigm enables video codecs to operate with reversed complexity, in which the complexity is shifted from the encoder toward the decoder. Its performance is heavily dependent on the quality of the side information generated
