A Novel Rate Estimation Model for Mode Decision of H.264/AVC
Rate Estimation Model Mode Decision H.264/AVC
2009/12/31
To acquire the optimal coding mode of each macroblock, the H.264/AVC encoder exhaustively calculates the ratedistortion cost for all available modes and chooses the minimum one as the best mode. There...
Effective algorithms for fast transcoding of AVS to H.264/AVC in the spatial
AVS H.264/AVC Transcoding Mode mapping
2007/12/31
This paper proposes a transcoding scheme from AVS to H.264/AVC. As highcompression
video coding standards, H.264/AVC jointly developed by MPEG and ITU and
AVS developed by the Audio Video Coding Sta...
A context-based adaptive fast Intra_4x4 prediction mode decision algorithm for H.264/AVC video coding
context-based fast Intra_4x4 prediction mode decision algorithm H.264/AVC video coding
2007/12/31
In this paper, we propose a context-based adaptive fast Intra_4x4 prediction mode decision algorithm for H.264/AVC. Firstly, a 3-order Markov random field model is introduced to describe the spatial d...
A Novel Two-Pass VBR Coding Algorithm for the H.264/AVC Video Coder Based on a New Analytical R-D Model
Two-Pass VBR Coding Algorithm the H.264/AVC Video Coder Analytical R-D Model
2007/12/31
In this paper, the generalized Gaussian distribution is employed first to model the 16(4*4) integer transform coefficients of the residue image in H.264 videos. Then the distortion-rate function of ge...
Adaptive Block-Size Transform Based on Extended Integer 8x8/4x4 Transforms for H.264/AVC
Block-Size Transform Extended Integer 8x8/4x4 Transforms H.264/AVC
2006/12/31
In this paper, a low-complexity Adaptive Block-size Transform (ABT) scheme is proposed for the H.264/AVC.The integer 8x8/4x4 discrete cosine transforms with an extended relation are applied to the pro...
Reducing Spatial Resolution for MPEG-2 to H.264/AVC Transcoding
Reducing Spatial Resolution MPEG-2 to H.264/AVC Transcoding
2005/12/31
Transcoding is an important technique for reducing the bit rate or spatial resolution to meet the constrained transmission bandwidths and terminal capabilities. In this paper, we propose a spatial dow...
Mode Mapping Method for H.264/AVC Spatial Downscaling Transcoding
Mode Mapping Method H.264/AVC Spatial Downscaling Transcoding
2004/12/31
Transcoding is a very effective method for universal media adaptation. Spatial resolution downscaling is one of the most popular transcoding applications. Although a number of transcoding methods have...
