A Fast and Low-complexity Motion Estimation for UHD HEVC
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...
متن کاملMotion Estimation and Inter Prediction Mode Selection in HEVC
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...
متن کاملMotion Estimation Algorithm for HEVC Suitable for Hardware Implementation
HEVC being developed in the video coding standard(The video coding standard of HEVC being developped ) is a new generation of video coding standards for HD resolution video encoding. It is difficult to implement HEVC real time coding in current hardware for the algorithm’s complextivity, so the algorithm optimization and hardware acceleration of HEVC become research hot spots. The motion estima...
متن کاملEfficient Pu Mode Decision and Motion Estimation for H.264/avc to Hevc Transcoder
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...
متن کاملImplementation of Motion Estimation Algorithm for H.265/HEVC
The most essential part of almost all video coding standards such as H.262/MPEG-2, H.264/MPEG-4 and newly emerged High Efficiency Video Coding (H.265/HEVC) is Motion Estimation. HEVC provides better performance in compression and efficiency in coding for Beyond HD and UHD videos. The main drawback is its computationcomplexity. The complexity is mainly due to Motion Estimation (ME), as it consum...
