Fast half-pel searching method on the basis of SAD values according to integer-pel search and random variable corresponding to each macro block |
摘要 |
The present invention relates to a half-pel motion estimation method. The calculation object half-pel, which is in the block of the previous or next reference frame, is not estimated additionally for each block of the current frame divided into blocks of a predetermined size. The present invention suggests an algorithm that can perform half-pel search only with a SAD value used in integer-pel search and a random variable for correcting errors. Since the present invention does not have to generate half-pel for motion estimation, the calculation amount is amazingly reduced and the calculation time is reduced.
