HEVC: The New Gold Standard for Video Compression: How Does HEVC Compare with H.264/AVC?
TLDR
In this paper, the Joint Collaborative Team on Video Coding (JCT-VC) was established with the objective to develop a new high-performance video coding standard for mobile applications.Abstract:
Digital video has become ubiquitous in our everyday lives; everywhere we look, there are devices that can display, capture, and transmit video. The recent advances in technology have made it possible to capture and display video material with ultrahigh definition (UHD) resolution. Now is the time when the current Internet and broadcasting networks do not even have sufficient capacity to transmit large amounts of HD content-Let alone UHD. The need for an improved transmission system is more pronounced in the mobile sector because of the introduction of lightweight HD resolutions (such as 720 pixel) for mobile applications. The limitations of current technologies prompted the International Standards Organization/International Electrotechnical Commission Moving Picture Experts Group (MPEG) and International Telecommunication Union-Telecommunication Standardization Sector Video Coding Experts Group (VCEG) to establish the Joint Collaborative Team on Video Coding (JCT-VC), with the objective to develop a new high-performance video coding standard.read more

Selective intra prediction in HEVC planar and angular modes for efficient near-lossless video compression
Abhilash Antony,G. Sreelekha +1 more
TL;DR: This work proposes two selective intra prediction strategies (SIP) which select the best prediction mode from the block-based and sample-based predictions at the pixel level and provides significant improvements in coding gain and run time for the proposed near-lossless SIP algorithms.

Small-Size Algorithms for the Type-I Discrete Cosine Transform with Reduced Complexity
TL;DR: Several algorithmic solutions for implementing type-I DCTs for small lengths N=2,3,4,5,6,7,8 is presented and the effectiveness is due to the possibility of fortunate factorization of the small-size DCT-I matrices, which reduces the complexity of implementing transformations of this type.

Towards jointly optimal spatial prediction and adaptive transform in video/image coding
TL;DR: This paper proposes a new approach to combined spatial (Intra) prediction and adaptive transform coding in block-based video and image compression, which is implemented within the H.264/AVC intra mode, and is shown in experiments to significantly outperform the standard intra modes, and achieve significant reduction of the blocking effect.
