HEVC and VP9 are the current state-of-the-art in video compression, thus, it is expected that in the near future these new codecs will replace their predecessors. However, the process of converting video contents compressed with one standard to those using another standard is highly computationally expensive, since a priori the video contents must be ...

High Efficiency Video Coding(HEVC)
2013HEVC the latest standard is presented. Comparison with H.264/AVC ( Chap. 4) is cited. The focus is on overview of HEVC rather than a detailed description of tools and techniques that constitute the encoder. A plethora of projects listed at the end challenges the implementation and futher research related to HEVC.

Spatially Scalable Video Coding For HEVC
IEEE Transactions on Circuits and Systems for Video Technology, 2012Spatially scalable video coding (SSVC) provides an efficient way to transmit one video at different resolutions. Based on the emerging High Efficiency Video Coding (HEVC), we propose an SSVC scheme to support both single-loop (SL) and multiloop (ML) solutions by enabling different interlayer prediction mechanisms. Specifically, we employ two interlayer

Quadtree Degeneration for HEVC
IEEE Transactions on Multimedia, 2016The quadtree is one of the most advanced techniques contributing to the excellent compression performance of high efficiency video coding (HEVC). However, the computational complexity increases because the quadtree examines all coding unit (CU) sizes to obtain the optimal CU partitioning.

State of HEVC Bitrates in 2014: Comparing HEVC, H.264, and MPEG-2
SMPTE Motion Imaging Journal, 2014This paper presents the results of empirical testing of high-efficiency video coding (HEVC) for standard-definition (SD), high-definition (HD), and ultra-high-definition (UHD), including data from hundreds of encoding tests across a variety of bitrates.

Fast Motion Estimation Algorithm for HEVC
2012 IEEE Second International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 2012Motion Estimation is an essential process in many video coding standards like MPEG-2, H.264/AVC and HEVC. Despite Motion Estimation has been used at the encoder, it is expected to be used in future consumer devices in the distributed video coding architectures. But the Motion Estimation itself consumes more than 50% coding complexity or time to encode.

HEVC Transform and Quantization
2014This chapter provides an overview of the transform and quantization design in HEVC. HEVC specifies two-dimensional transforms of various sizes from 4 × 4 to 32 × 32 that are finite precision approximations to the discrete cosine transform (DCT). In addition, HEVC also specifies an alternate 4 × 4 integer transform based on the discrete sine transform ...

An HEVC bitstream consists of a sequence of data units called network abstraction layer (NAL) units. Some NAL units contain parameter sets that carry high-level information regarding the entire coded video sequence or a subset of the pictures within it.

Saliency based perceptual HEVC
2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW), 2014Saliency represents the probability of human attention over the image therefore is important in understanding the importance of different areas in the image. In this paper, we consider how to utilize the saliency information in HEVC video coding. The graph-based visual saliency is incorporated with the quantization control in HEVC to reduce the bit ...

Multi-Intensity Illuminated Infrared video compression using MV-HEVC and 3D-HEVC
2017 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2017Multi-Intensity Illuminated Infrared (MIIR) video is a new type of infrared video which solves the problem of improper illumination conditions for ordinary infrared cameras for nighttime surveillance. However, its time-varying intensity makes it hard to be compressed with traditional video coding methods.
