摘要： A decoding apparatus partitions a video coding block based on coding information into two or more segments including a first segment and a second segment. The coding information comprises a first segment motion vector associated with the first segment and a second segment motion vector associated with the second segment. A co-located first segment in a first reference frame is determined based on the first segment motion vector and a co-located second segment in a second reference frame is determined based on the second segment motion vector. A predicted video coding block is generated based on the co-located first segment and the co-located second segment. A divergence measure is determined based on the first segment motion vector and the second segment motion vector and a first or second filter is applied depending on the divergence measure to the predicted video coding block.

摘要： The present invention provides an encoder for encoding a frame of a video sequence and a corresponding decoder. The encoder comprises a partitioner and an entropy coder. The partitioner is configured to receive a current block of the frame and obtain a list of candidate geometric partitioning (GP) lines. Each of the candidate GP lines is generated based on information of one or more candidate neighbor blocks of the current block. The partitioner is further configured to determine a final GP line that partitions the current block into two segments, select a GP line from the list of GP lines to obtain a selected GP line, and generate a GP parameter for the current block. The GP parameter includes offset information indicating an offset between the final GP line and the selected GP line. The entropy coder is configured to encode the GP parameter.
