Rate-Distortion Optimization for VBR Environments Using a Motion Compensated Wavelet Coder
نویسنده
چکیده
This paper presents a motion-compensated wavelet video coder applicable to VBR transmission where constant distortion coding at minimal rate is desired. The R-D optimization is achieved by jointly optimizing the coding parameters in both the variable block size motion estimation and the region-based embedded wavelet coding of the residual. Experiments are performed by matching PSNR prooles from TM5 and by constant distortion coding using the average PSNR from TM5. Results show that visual quality is maintained at a rate reduction of 22%-29%.

This paper proposes a frame rate-control scheme with a MINMAX distortion criterion in the framework of a rate-distortion optimized motion compensated embedded wavelet coder. The MINMAX criterion aims to minimize the maximum distortion in a group of pictures (GOP) for a given bit rate. The proposed frame level bit allocation scheme combined with R-D optimized within frame allocation allows preci...

| Model-based video synthesis is combined with block-based motion-compensated video coding for rate-distortion eecient transmission of head-and-shoulder sequences. Two frames are utilized for block-based motion-compensated prediction of the current video frame where one frame is the previously reconstructed one and the other frame is provided by a model-based coder. The model-based coder uses a...
متن کاملVideo coding using embedded wavelet packet transform and motion compensation
In this paper, we propose a hybrid video coder using the wavelet packet transform and motion compensation. To reduce the computational complexity of the wavelet packet decomposition, a novel criterion based on the rate-distortion function is proposed. After the wavelet packet transform, the successive quantization scheme and the adaptive arithmetic coder are applied for lossy wavelet coe cient ...
