ABSTRACT
|
| Motion Estimation (ME) is an important part of the MPEG-4 encoder, since it could significantly affect the output quality of the encoded sequence. Unfortunately this feature requires a significant part of the encoding time especially when using the straightforward Full Search (FS) Algorithm. The Diamond Search (DS) was recently accepted as a fast motion estimation algorithm for the MPEG4 VM. In this report we verify the results extracted by the Advanced Diamond Zonal Search with Embedded Radar algorithm (ADZS-ER), proposed by Alexis M. Tourapis, Oscar C. Au, Ming L. Liou, and Guobin Shen (ISO/IEC JTC1/SC29/WG11, MPEG99/M4980). The experiments were carried out under the same conditions and the results verify the superiority of the proposed algorithm towards the DS algorithm, especially in the high bit rate cases, regarding the speed (in terms of number of checking points and total encoding time) and the quality (in terms of PSNR) of the output sequence.
