    Abstract: 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.

    Abstract: A depth image filtering method, and a filtering threshold obtaining method and apparatus are provided. The method in the embodiments of the present invention includes: determining, for each pixel in an adjacent area of a pixel of a to-be-filtered depth image, whether the pixel meets a preset condition; determining a set of pixels meeting the preset condition; and determining a pixel value of the pixel of the to-be-filtered depth image according to pixel values of the pixels in the set. According to the embodiments of the present invention, a ringing effect at an edge of a depth image is effectively removed, and discontinuity of the depth image is reduced, thereby improving quality of a video image.

    Abstract: A method, an apparatus and a system for a rapid motion search applied in template matching are disclosed. The method includes: selecting motion vectors of blocks related to a current block as candidate motion vectors of the current block; after the uniqueness of a series of the candidate motion vectors of the current block is maintained, calculating the cost function of the candidate motion vectors in a corresponding template area of a reference frame, and obtaining the motion vector of the best matching template from the candidate motion vectors of the current block. In the embodiments of the present invention, there is no need to determine a large search range and no need to determine the corresponding search path template, and it is only necessary to perform a search in a smaller range.

    Abstract: 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.
