This paper presents a fast algorithm implement the variable block size motion estimation for H.264 system. The fast algorithm is proposed based on hardware-oriented concept for regular VLSI design. We present a fast algorithm with 9-point block (9PB) concept to reduce the computational complexity. The vector is estimated with the continuous search to reduce the bandwidth of I/O memory. Also, variable...
Fractional motion estimation (FME) is widely used in video compression standards. In H.264/AVC, the precision of motion vector is down to quarter pixels to improve the coding efficiency. However, FME occupies over 45% of the computation complexity in an H.264 encoder and this high complexity limits the processing capability. In this paper, a single-iteration full search FME is proposed. By the algorithm...
In this paper, a hardware efficient coarse-to-fine fast algorithm for H.264 motion estimation is proposed. We present hardware friendly two-step searching flow to obtain the 41 MVs of the variable block size motion estimation (VBSME) efficiently. At the first step, the candidate block down-sampling technique and the multi-level successive elimination algorithm (MSEA) with fixed 16 times 16 block-matching...
