摘要： Systems and methods of signaling different filter structures for each pixel or sub-pixel position in motion compensation prediction video coding are provided. An encoder signals to a decoder one filter structure among a plurality of pre-defined candidates that is used for a respective pixel or sub-pixel position. In accordance with one embodiment, filter structures signaled to the decoder from the encoder “switch” between directional filter and radial filter structures during interpolation at the sub-pixel level. In accordance with another embodiment, filter structures that are signaled may switch between a directional filter structure and a separable filter structure at the sub-pixel level. Thus, not only can an encoder switch between different filter structures during interpolation, but a filter structure pair is provided that the encoder can utilize to interpolate a wide range of signals without increasing tap-length.

摘要： A system and method for implementing an adaptive interpolation filter structure that achieves high coding efficiency with significantly less complexity than more conventional systems. In various embodiments, a set-of integer pixels are defined that are used in the interpolation process to obtain each sub-pixel sample at different locations. Samples at each sub-pixel positions are generated with independent pixel-aligned one-dimensional (1D) adaptive interpolation filters. The filter coefficients are be transmitted to a decoder or stored into a bit stream. At the decoder end, the received filtered coefficients may be used in an interpolation process to create a motion-compensated prediction.

摘要： In digital video image encoding and decoding, a filter type is selected based on symmetrical properties of the images and coefficient values of an interpolation filter are calculated based on the selected filter type. Coefficient values, filter tap-length and selected filter-type are provided in the encoded video data. Coefficient values are also calculated based on a prediction signal representative of the different between a video frame and a reference image. The prediction signal is calculated from the reference image based on a predefined base filter and motion estimation performed on the video frame. The predefined base filter has fixed coefficient values. Coefficient values are selected from interpolation of pixel values in a selected image segment in the video frame. Symmetry properties of images can be a vertical symmetry, a horizontal symmetry and a combination thereof, so that only a portion of the filter coefficients are coded.

摘要： The invention relates to coding of depth information for multi-view video coding. Different parameters and/or any features from picture encoding or the encoded and reconstructed pictures may be used in the coding of the depth information, especially in filtering the depth picture using e.g. a loop filter in the depth coding loop. The same principle may be applied in decoding, that is, the decoded (texture) pictures and parameters may be used to control the decoding of the depth data, e.g. to control the filtering of the depth data in a loop filter. Parameters and data that may be used as such control may comprise features extracted from the reconstructed pictures, the encoded video data and parameters, the motion estimation data and others.
