Adaptive Selection of Motion Estimation Block Size for Rate-Distortion Optimization
The employment of the Variable Block size motion estimation technique introduces a new optimization issue for the motion compensated transform coding. An increase in bit rate allocation is necessary to accommodate VBS motion vectors. An algorithm for adaptive selection of motion estimation block size is proposed for R-D optimal motion estimation. It avoids reduction in the block size in visuall...
متن کاملRate-distortion optimization between the hierarchical variable block size motion estimation and motion sequence coding
Recently, a variable block size(VBS) motion estimation technique has been employed to improve the performance of the motion compensated transform coding(MCTC). This technique allows larger blocks to be used when smaller blocks provide little gain, saving the bit rates, especially for areas containing more complex motion. However, the employment of the VBS motion estimation technique addresses a...
متن کاملAn adaptive partial distortion search for block motion estimation
Fast search algorithms for block motion estimation reduce the set of possible displacements for locating the motion vector. All algorithms produce some quality degradation of the predicted image. To reduce the computational complexity of the full search algorithm without introducing any loss in the predicted image, we propose a Hilbert-grouped partial distortion search algorithm (HGPDS) by grou...

The conventional search algorithms for block motion estimation reduce the set of possible displacements for locating the motion vector. All of these algorithms produce some quality degradation of the predicted image.

متن کاملMotion and disparity field estimation using rate-distortion optimization
A rate-distortion framework is used to de ne a displacement vectoreld estimation technique for use in video coding. This technique achieves maximum reconstructed image quality under the constraint of a target bitrate for the coding of the vector sequence. The technique may be adapted so as to limit its smoothing e ect to homogeneous areas and avoid highly textured areas and edges. Use of this t...
