In this paper, we propose a fast decision method scheme to reduce encoder complexity of high efficiency video coding. It is an early detection of SKIP mode in one CU-level based on the differential motion vector (DMV) and coded block flag (CBF). Experimental results show that the encoding complexity can be reduced by up to 34.55% in random access (RA) configuration and 36.48% in low delay (LD) configuration...
In this paper, we propose a fast intra mode decision for high efficiency video coding (HEVC) to reduce its encoding complexity. It proposes an early termination method under its hierarchical structure that uses the intra prediction mode (IPM) of corresponding previous-depth prediction unit (PU) and block size of current-depth transform unit (TU). To reduce even more complexity, the number of candidates...
In this paper, an interleaved motion vector coding is proposed which supports flexible coding order of motion vector components according to directional property of vertical and horizontal components in motion vector field. It requires no additional information for adaptively selecting the coding order.
In this paper, an improved deblocking filter for intra blocks is proposed. By applying different strength of deblocking filter adaptively to intra blocks based on intra prediction mode, the proposed method not only improves visual quality but also achieves coding performance.
In this paper, we propose a new motion vector coding scheme using decoder selectable predictive motion vector. To utilize more efficient PMV without any extra signaling data, the proposed encoder selects a predictive motion vector which can be autonomously selected by decoder among various candidate predictive motion vectors. To do so, the proposed encoder identifies decoder selectable predictive...
In this paper, we propose a new motion vector coding scheme using optimal predictor. To improve coding performance of motion vector data, the proposed encoder selects an optimal predictive motion vector that produces minimum bits for the given motion vector. The proposed decoder estimates the optimal predictive motion vector without additional information from encoder for indicating which predictor...
Intra coding has relatively low coding efficiency, however, it is an indispensable coding tool since it provides random access and low-complex encoding. A new intra prediction mode coding scheme is proposed in this paper to improve its coding efficiency. The proposed scheme can save bits used in representing intra prediction mode by selectively not transmitting intra prediction mode bits. If the proposed...
The H.264/AVC standard employs the predictive motion vector coding technique using the median predictor of spatially neighboring three motion vectors. Although the median is effective in reducing redundancy, it is not always optimal in minimizing bits. To solve the matter, a new motion vector coding scheme, known as, MV competition in which decoder is signaled on the selected optimal PMV, has been...
Currently, most Korean domestic 3G terminals use VT (video telephony) service. This service is based on circuit switching with video codec standard of H.263 or MPEG-4. There is a strong need for enhancing image qualities by VT terminal before transmitting, however, its limited processing capability does not allow for such processing. In this paper, we propose a low complexity video post-processing...
Recently proliferating heterogeneous video service environments should be able to deal with many different transmission speeds, image sizes, or qualities of video. However, not many existing video compression standards satisfy those necessities. To satisfy the functional requirements, the standardization of the H.264/AVC Scalable Video Coding (SVC) technique has been recently completed. It is an extension...
