Motion estimation%Inverse telescopic search%VLSI
This paper presents a modified multi-resolution telescopic search algorithm (MRTlcSA) for the blockmatching motion estimation. A novel inverse telescopic search is substituted for the conventional telescopic search, that reduces the on-chip memory size and memory bandwidth for VLSI implementation. In addition, strategies of motion track and adaptive search window are applied to reduce the computational complexity of motion estimation. Simulation results show that, compared with the MRTlcSA, the proposed algorithm reduces the computational load to only 30%while preserving almost the same image quality. Comparisons on hardware cost and power consumption of the VLSI implementations using the two algorithms are also presented in the paper.``
