This paper presents a new spatio-temporal motion estimation algorithm for video coding. The algorithm is based on optimization theory and consists of the strategies including 3D spatio-temporal motion vector prediction, modified one-at-a-time search scheme, and multiple update paths. The simulation results indicate our algorithm is better than other recently proposed ones under the same computational budget and is very close to full search. The low-cost feature and regular demand of computational resource make our algorithm suitable for VLSI implementation. The algorithm also makes single chip solution for high-definition coding feasible
