摘要： A method and apparatus for deriving MV/MVP (motion vector or motion vector predictor) or DV/DVP (disparity vector or disparity vector predictor) associated Skip mode, Merge mode or Inter mode for a block of a current picture in three-dimensional (3D) video coding are disclosed. The 3D video coding may use temporal prediction and inter-view prediction to exploit temporal and inter-view correlation. MV/DV prediction is applied to reduce bitrate associated with MV/DV coding. The MV/MVP or DV/DVP for a block is derived from spatial candidates, temporal candidates and inter-view candidates. For the inter-view candidate, the position of the inter-view co-located block can be located using a global disparity vector (GDV) or warping the current block onto the co-located picture according to the depth information. The candidate can also be derived as the vector corresponding to warping the current block onto the co-located picture according to the depth information.

摘要： The present invention utilizes depth images captured by a depth camera to detect foreground/background. In one embodiment, the method comprises establishing a single background distribution model, updating the background distribution model if a new depth value for the pixel can be represented by the background distribution model, skipping update of the background distribution model if the pixel is before the background, and replacing the background distribution model if the pixel is behind the background. In case that the background distribution model does not exist initially, a new background distribution model is created. In one embodiment of the present invention, the non-meaningful pixels are handled. In another embodiment, fluctuation of the depth value due to noise is handled by using a candidate background distribution model. In yet another embodiment, the noise for pixels around object edges is handled by using a mixture of two background distribution models.

摘要： An apparatus and method for motion vector prediction for a current block in a picture are disclosed. In video coding systems, the spatial and temporal redundancy is exploited using spatial and temporal prediction to reduce the information to be transmitted. Motion Vector Prediction (MVP) has been used to further conserve the bitrate associated with motion vector. In conventional temporal MVP, the predictor is often based on a single candidate such as the co-located motion vector in the previous frame/picture. If the co-located motion vector in the previous frame/picture does not exist, the predictor for the current block is not available. A technique for improved MVP is disclosed where the MVP utilized multiple candidates based on co-located motion vectors from future and/or past reference pictures. The candidates are arranged according to priority order to provide better availability of MVP and also to provide more accurate prediction. Furthermore, the MVP technique disclosed can be operated in a closed-loop fashion so that no additional side information or minimum additional side information is required.

摘要： One of the embodiments of the invention provides an input-output calibration method performed by a processing unit connected to an output device and an input device. The output device and the input device correspond to an output device coordinate system and an input device coordinate system, respectively. The processing unit first derives M calibration points' coordinates in the input device coordinate system by using the input device to sense a viewer specifying the M calibration points' positions, wherein M is a positive integer. Then, the processing unit uses the M calibration points' coordinates in the output device coordinate system and coordinates in the input device coordinate system to derive the relationship between the output device coordinate system and the input device coordinate system.

摘要： The invention provides a motion prediction method. First, a plurality of motion vector predictors is obtained to be included in a candidate set for motion prediction of a current unit of a current frame. Whether the current frame is a non-reference frame which is not referred to by other frames for motion prediction is then determined. When the current frame is not the non-reference frame, any motion vector predictor corresponding to a previously coded frame is removed from the candidate set, and a motion vector of the current unit is predicted according to the motion vector predictors of the candidate set.
