Subblock based motion vector predictor displacement vector reordering using template matching
摘要:
Aspects of the disclosure provide a method and an apparatus for video encoding/decoding. The apparatus includes processing circuitry for: receiving prediction information of a current coding block in a current picture from a coded video bitstream, the prediction information indicating that the current coding block is coded using a subblock-based temporal motion vector prediction (SbTMVP) mode; deriving multiple displacement vector (DV) candidates by applying multiple DV offset candidates to a fixed DV predictor of the current coding block; comparing a template of the current coding block with each of multiple templates, each template of the multiple templates being located at a position specified by a corresponding one of the multiple DV candidates; calculating a cost value associated with each one of the multiple DV offset candidates based on the comparing; and reordering DV offset indices of the multiple DV offset candidates based on their calculated cost values.
