چکیده

Motion estimation is one of the most computationally challenging parts of any video encoder. An estimated 50% to 70% encoder complexity is due to motion estimation. Recent video coding standards like H.264/MPEG-4(AVC) and HEVC include a sophisticated motion estimation algorithm called Test Zone Search. This paper examines the algorithms designed to perform Coding Unit type and size selection in HEVC and the proposed improvements to the Test Zone Search algorithm with respect to HEVC while also suggesting further improvements. Key-Words: Inter prediction, coding unit, depth, motion estimation, test zone search, H.264/MPEG-4(AVC), HEVC.

Fast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard

three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...

Context-adaptive based CU processing for 3D-HEVC

The 3D High Efficiency Video Coding (3D-HEVC) standard aims to code 3D videos that usually contain multi-view texture videos and its corresponding depth information. It inherits the same quadtree prediction structure of HEVC to code both texture videos and depth maps. Each coding unit (CU) allows recursively splitting into four equal sub-CUs. At each CU depth level, it enables 10 types of inter...

A Fast Pu Mode Decision Algorithm for H.264/avc to Hevc Transcoding

H.264/AVC has been widely applied to various applications. However, a new video compression standard, High Efficient Video Coding (HEVC), had been finalized recently. 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 mo...

Pixel Decimation of RD-Cost Functions in the HEVC Encoder

We present and analyse schemes for the improvement of computational complexity in the current HEVC (High Efficiency Video Coding) standard, by a subsampling of the block-matching distortion cost functions used in the encoding process. HEVC improves on prior standards considerably in coding (compression) efficiency, with a large set-back in time complexity for inter and intra prediction processe...
