A fast motion estimation algorithm having computational complexity independent of search range is presented for MPEG-2 video encoding. The algorithm is based on spatial and temporal correlation of motion vectors. The algorithm yields good tradeoff between motion estimation distortion and number of computations. The speed up achieved by the algorithm is in the order of 160-250 and the SAD increase is 8-15% compared to full search. The number of bits required to code motion vectors is less as the
