METHOD FOR PREDICTING DISPARITY VECTOR BASED ON BLOCKS FOR APPARATUS AND METHOD FOR INTER-LAYER ENCODING AND DECODING VIDEO

摘要

An inter-layer video decoding method includes searching for a neighboring block candidate which neighbors a current block and has a motion vector in an inter-layer direction, from among spatial and temporal neighboring block candidates; when the neighboring block candidate having the motion vector in the inter-layer direction is found, setting the motion vector in the inter-layer direction of the found neighboring block candidate as a disparity vector of the current block; when the neighboring block candidate having the motion vector in the inter-layer direction is not found, searching for a neighboring block candidate having disparity vector information from among the spatial and temporal neighboring block candidates; and when the neighboring block candidate having the disparity vector information is found, predicting a disparity vector of the current block based on the disparity vector information of the found candidate.

1. An inter-layer video decoding method comprising:
searching for a neighboring block candidate which neighbors a current block and has a motion vector in an inter-layer direction from among a spatial neighboring block candidate located at a left side of the current block, a spatial neighboring block candidate located at a top of the current block, and temporal neighboring block candidates at co-located locations of the current block; when the neighboring block candidate having the motion vector in the inter-layer direction is found, setting the motion vector in the inter-layer direction of the found neighboring block candidate as a disparity vector of the current block; when the neighboring block candidate having the motion vector in the inter-layer direction is not found, searching for a neighboring block candidate which neighbors the current block and has disparity vector information from among the spatial neighboring block candidate located at the left side of the current block, the spatial neighboring block candidate located at the top of the current block, and the temporal neighboring block candidates at the co-located locations of the current block; and when the neighboring block candidate having the disparity vector information is found, predicting a disparity vector of the current block based on the disparity vector information of the found neighboring block candidate.
