A low-cost center-biased motion estimation algorithm for VLSI implementation
Zhaoyang Zhang · Journal of Optoelectronics·laser · 2010
Most VLSI implementations of video coding adopt full search motion estimation approach,and there is no high efficient center-biased method.A candidates selected search algorithm is proposed which can decrease the resource cost of search.A Center-biased method which is used to predict the high probability area is also proposed.The experiments show that the algorithm owns a good rate-distortion performance.And the algorithm has been implemented on FPGA platform.The synthesis result shows that the cost is decreased by 64%.The algorithm can be used in SDTV and HDTV encoder.
