In this paper, we propose a novel fast and low-complexity Motion Estimation (ME) algorithm for Ultra High Definition (UHD) High Efficiency Video Coding (HEVC). Motion estimation occupies 77~81% of the amount of computation in HEVC. After all, the main key of video codec implementation is to find a fast and low-complexity motion estimation algorithm and architecture. We analyze the previous moti...

H.265 or High Efficiency Video Coding (HEVC) has been developed with a goal to achieve significant compression relative to existing standards in the range of 50% bit rate reduction for the same perceptual video quality [1]. HEVC has been designed to address nearly all existing applications of H.264/AVC and additionally to focus on two key issues: (a) increased video resolution and (b) increased...

This paper presents a modified deblocking filter for depth video coding in the 3D video coding extension of High Efficiency Video Coding (3D-HEVC). The conventional 3D video coding extension of HEVC (3D-HEVC) employs a deblocking filter and sample adaptive offset (SAO) in the loop filter in which both tools are applied to color video coding only. Nevertheless, the deblocking filter can smooth o...

This paper presents several optimization algorithms for a High Efficiency Video Coding (HEVC) encoder based on single instruction multiple data (SIMD) operations and data-level parallelism. Based on the analysis of the computational complexity of HEVC encoder, we found that interpolation filter, cost function, and transform take around 68% of the total computation, on average. In this paper, se...

H.264/AVC has been widely applied to various applications. However, a new video compression standard, High Efficient Video Coding (HEVC), had been finalized in 2013. In this work, a fast transcoder from H.264/AVC to HEVC is proposed. The proposed algorithm includes the fast prediction unit (PU) decision and the fast motion estimation. With the strong relation between H.264/AVC and HEVC, the mod...

With the emergence of the High Efficiency Video Coding (HEVC) standard, significant additional video compression improvements have recently been provided, notably around 50% increased compression performance regarding the previously available standard video coding solutions. Moreover, the same requirements which demanded some years ago for a scalable extension of the H.264/AVC standard, named S...

In this paper, we first introduce a spatio-temporal Just Noticeable Difference (JND) model based perceptual video coding (PVC) scheme which is completely compliant with HEVC. We incorporate into HEVC quantization process a JND model that takes into account both the temporal JND characteristics of temporal masking effects and the spatial JND characteristics of the luminance adaptation and contra...

The high efficiency video coding (HEVC) standard has significantly improved compression performance for many applications, including remote desktop and desktop sharing. Screen content video coding is widely used in applications with a high demand for real-time performance. HEVC usually introduces great computational complexity, which makes fast algorithms necessary to offset the limited computi...

High Efficiency Video Coding (HEVC) is a new video coding standard following H.264/AVC. By introducing a flexible coding unit (CU), which can be recursively divided from 64 64  to 8 8 blocks in a Quadtree-Structure, HEVC achieves significantly higher coding efficiency than the previous standards. With the flexible CU structure, HEVC can effectively adapt to complicated contents with a smaller...
