V.V.Gohokar, V.N.Gohokar . Adaptive Selection of Motion Estimation Block Size for Rate-Distortion Optimization. International Journal of Computer Applications. 17, 4 ( March 2011), 44-48. DOI=10.5120/2205-2802
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 visually irrelevant areas. Improvement in R-D performance is obtained at reduced complexity.
