A method and apparatus for determining motion vector for inter prediction

Abstract

The present disclosure relates to a method and an apparatus for determining a motion vector for inter prediction, the method comprising: when motion estimation is performed on a current block, based on a prediction distortion degree, an encoding bit number, and a decoding complexity brought about by performing inter prediction on the current block using the motion vector of the current block, the cost of each motion vector candidate of the current block is calculated, the prediction distortion degree represents the distortion degree between the original value and the prediction value of the current block, the coding bit number represents the bit number needing to be distributed for coding the current block, and the decoding complexity represents the decoding complexity of the coded current block; and the calculated motion vector candidate is determined with the lowest cost as the motion vector of the current block.

Description

technical field [0001] The present disclosure relates to the field of audio technology, and more particularly, to a method and device for determining a motion vector for inter-frame prediction. Background technique [0002] The HEVC / H265 codec standard has emerged as the demand for a video codec for efficiently encoding or decoding high-resolution or high-quality video content has increased. However, although the HEVC / H265 codec standard can save about 50% of the code rate compared with the AVC / H264 standard at the same quality, the decoding complexity of HEVC is also significantly increased. Considering that there are still a large number of devices that do not support HEVC hardware For decoding, in large-scale application scenarios, the power consumption caused by decoding complexity is a real problem that seriously affects the user experience. Contents of the invention [0003] The present disclosure provides a method and an apparatus for determining a motion vector fo...
