Comparative and performance analysis of HEVC and H.264 Intra frame coding and JPEG2000

Analysis of Frame Partitioning in HEVC

The paper presents analysis of frame partitioning in the next generation video coding standard HEVC. Complex study on frequency of the particular coding unit, prediction unit and transform unit sizes selection made by the encoder compliant with HEVC technology is included. General conclusions based on extensive experiments for HD video sequences are presented. Such knowledge may be the first st...

Reference frame selection in a hardware-based HEVC encoder

The multiple-reference-frame motion estimation (ME) is one of the features to improve the compression efficiency. However, the computational complexity for prediction increases in proportion to the number of reference frames. This paper proposes the reference frame selection algorithm for a hardware-based HEVC encoder. The integer-ME explores multiple reference frames to find the best one and t...

Improved Prediction Estimation Based H.264 to HEVC Intra Transcoding

HEVC achieves significant coding efficiency improvement which is the best choice of 3D content but at a cost of much higher computation complexity. We propose a prediction estimation based H.264 to HEVC intra transcoder which can reach the high speed up for CU splitting with minor loss of coding efficiency for Intra picture. Our proposed method uses not only the intra prediction mode, predictio...

The Algorithm of Fast Intra Angular Mode Selection for HEVC

In this paper, we propose an algorithm of angular mode selection for high-performance HEVC intra prediction. HEVC intra prediction is used to remove the spatial redundancy. Intra prediction has a total of 35 modes and block size of 64x64 to 4x4. Intra prediction has a high amount of calculation and operational time due to performing all 35 modes for each block size for the best cost. The angula...
