Motion estimation (ME) is a key operation for video compression. In fact, it contributes heavily to the compression efficiency by removing temporal redundancies. This process is the most critical part in a video encoder and can consume itself more than 50% of coding complexity or computational coding time. To reduce the computational time, many fast ME(More)
High-efficiency video coding is the latest standardization effort of the International Organization for Standardization and the International Telecommunication Union. This new standard adopts an exhaustive algorithm of decision based on a recursive quad-tree structured coding unit, prediction unit, and transform unit. Consequently, an important coding(More)
In this paper, a fast Coding Unit (CU) partitioning algorithm is proposed to reduce encoding time of HEVC test model (HM). HEVC is the new generation video codec which improves the coding efficiency significantly and provides more than 50% bit rate reduction while maintaining the same image quality compared to its predecessor H.264/AVC. Different sizes of(More)
High Efficiency Video Coding (HEVC) standard represents the newest video coding standard generation for both ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The new standard reduces bitrates by 50% compared to the existing standards using Advanced Video Coding (AVC) for equal video quality. This paper provides an overview of(More)
High Efficiency Video Coding is the latest video standard aiming to replace H264/AVC standard by improving significantly the coding efficiency and the compression performance which allows HEVC to be mostly suitable for high-definition videos for multimedia applications. However, the encoding process requires a high computational complexity that needs to be(More)
The latest High Efficiency Video Coding was aggregated in order to enhance the previous H264.AVC by a rate compression decrease of 50% with the same image quality. The HEVC intra prediction procedure requires a high computational complexity that needs to be alleviated. To this end, the paper proposes a new approach of intra prediction process without the(More)
HEVC is planned to provide better coding efficiency. However, this efficiency comes with an important computational complexity. Many works are undergoing to decrease the complexity of the encoder. Nevertheless, the analysis of the encoder' decision is necessary to have an idea about partitioning mode of the CUs in terms of size and type. This paper presents(More)
