解码影像的方法;METHOD FOR DECODING IMAGE

摘要

提供一种经由移动向量预测来决定移动向量的移动向量决定方法及装置。;所述移动向量决定方法涉及：决定候选移动向量清单，其包括经参考以便预测当前区块的移动向量的多个候选区块的移动向量；当多个候选区块中的第一候选区块的参考影像不同于当前区块的参考影像时，基于所述当前区块的参考影像以及所述第一候选区块的参考影像中的每一者为短期参考影像还是长期参考影像，决定是否使用所述候选移动向量清单中的第一候选区块的移动向量；以及藉由使用选自所述候选移动向量清单中所包括的移动向量的候选移动向量来决定所述当前区块的移动向量。;The motion vector determining method involves determining a candidate motion vector list comprising motion vectors of a plurality of candidate blocks referred so as to predict a motion vector of a current block, when a reference image of a first candidate block from among the plurality of candidate blocks is different from a reference image of the current block, determining whether or not to use a motion vector of the first candidate block from the candidate motion vector list, based on whether each of the reference image of the current block and the reference image of the first candidate block is a short-term reference image or a long-term reference image, and determining the motion vector of the current block by using a candidate motion vector selected from among the motion vectors comprised in the candidate motion vector list.
