%X Motion estimation refers to estimating 2D motion vector field of the scene or object according to temporal information redundancy in a clipped video.It plays a key role in the super resolution image restoration technique,which maps pixels of all low resolution observations onto corresponding pixels in the reference frame.So its accuracy is highly required.Block-based motion estimation is widely used in super resolution image restoration.This paper introduces the model of block-based motion estimation,summarizes four categories of fast motion estimation methods,describes in detail the search process of several influential algorithms belonging to the first category,and then compares several fast block-matching algorithms.
