An adaptive block size phase correlation motion estimation using smart multireference frames selection in frequency domain

The multiple reference frame motion compensation (MRMC) supported by H.264 makes use of redundaney between multiple IVanics to enhanee the coding efficiency over ihc techniques which use a single reference frame-motion compensation. However, searching the motion vectors in multiple frames is computationally expensive. This paper proposes a smart MR VIC selection technique, which has a lower search complexity without sacrificing video quality. To reduce the complexity of the motion estimation process, adaptive block size phase correlation motion estimation (ABS-PC-ME) technique using several prediction techniques is used. The proposed scheme has lower complexity compared with the conventional schemes. © 2007 IEEE.
