Learning for Video Compression With Hierarchical Quality and Recurrent Enhancement
TL;DR: Wang et al. as discussed by the authors proposed a Hierarchical Learned Video Compression (HLVC) method with three hierarchical quality layers and a recurrent enhancement network, where the frames in the first layer are compressed by an image compression method with the highest quality.

Scalable Coding of Plenoptic Images by Using a Sparse Set and Disparities
TL;DR: This paper proposes a lossy coding scheme to efficiently represent plenoptic images that inherits a scalable structure with three layers and shows that plenOptic images are compressed efficiently with over 60 percent bit rate reduction compared with High Efficiency Video Coding intra coding, and with over 20 percent compared with an High efficiency block copying mode.

Fast Decision of Block Size, Prediction Mode, and Intra Block for H.264 Intra Prediction
TL;DR: This paper proposes a variance- based algorithm for block size decision, an improved filter-based algorithm for prediction mode decision using contextual information, and a selection algorithm for intra block decision that exploits the relation between the rate-distortion characteristic and the best coding type.

Fast mode decision and motion estimation for H.264 with a focus on MPEG-2/H.264 transcoding
TL;DR: Simulation results demonstrate that the H.264 standard can be achieved significant complexity reduction while maintaining the coding efficiency.

Video Coding on Multicore Graphics Processors
TL;DR: A GPU based fast motion estimation is discussed to illustrate some design considerations in using GPUs for video coding, and the tradeoff between speedup and rate-distortion performance is highlighted.
