Abstract: The disclosure relates to an apparatus for coding a bit stream representing a three-dimensional video comprising a sequence of views, wherein a depth map is associated to each view, the depth map comprising depth information of the view with respect to a position to the camera capturing the view, the apparatus comprising: a partitioner for partitioning the depth map into coding units; a determiner for determining a type of model function for each coding unit based on the depth information of the coding unit; a reducer for reducing the coding unit to a single residual value for each segment generated by model function; and a signaler for signaling the model function used and the residual value into the bitstream.

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: 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.
