نویسندگان
چکیده
A new efficient type I architecture for motion estimation in video sequences based on the Full-Search Block-Matching (FSBM) algorithm is proposed in this paper. This architecture presents minimum latency, maximum throughput and full utilization of the hardware resources, combining both pipelining and parallel processing techniques. The implementation of an array processor for motion estimation in a single-chip using 0.25 m CMOS technology is presented. Experimental results show that this processor is able to estimate motion vectors in 4CIF video sequences at a rate of 16 frames/s.

Variable block size motion estimation (VBS-ME) is one of the contributors to H.264/AVC’s excellent coding efficiency. Due to its high computational complexity, however, VBS-ME needs acceleration for real-time high-resolution applications.

متن کاملAdaptive search area for fast motion estimation
In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...
