This paper presents a novel matching algorithm for fast motion estimation. The algorithm, called the Edge-matching First Block-matching Last Algorithm (EFBLA), first employs the edge-matching procedure to determine candidate motion vectors and then performs the conventional block matching with the SAD criteria on the candidates. The edge-matching procedure features low computation load and high degree of data reusability; therefore, it requires fewer operations and lower memory size compared with the full search algorithm. As the result of benchmarking and comparing to the full search algorithm, EFBLA may significantly save the computation load by 93.9% while the degradation of PSNR is very little.
