METHOD OF AND APPARATUS FOR ESTIMATING MOTION VECTOR BASED ON SIZES OF NEIGHBORING PARTITIONS, ENCODER, DECODER, AND DECODING METHOD

摘要

Provided are a method of and apparatus for estimating a motion vector using the sizes of neighboring partitions, an encoder, a decoder, and a decoding method. The method includes comparing the size of a first neighboring partition located to the left of the current block with the size of a second neighboring partition located above the current block and, if the size of the first neighboring partition and the size of the second neighboring partition are different from each other, estimating a motion vector of the larger one of the first neighboring partition and the second neighboring partition as the motion vector of the current block.
