摘要： The present invention relates to inter-view residual prediction and is characterized by obtaining residual data of a first reference block by using a motion vector of a neighboring block, obtaining residual data of a second reference block by using a reference view motion vector or a disparity vector, obtaining a residual data prediction value by using the residual data of the first reference block and the residual data of the second reference block, and coding a current texture block by using the residual data prediction value. The present invention can perform inter-view residual prediction by using a prediction value obtained using coded data of another view point belonging to the same time band to increase the accuracy of video data prediction by using a correlation between view points and reduce the amount of residual data to be transmitted, thereby improving the coding efficiency. In addition, the complexity in a coding process may be reduced by adding a condition for applying the inter-view residual prediction.

摘要： A method and apparatus for inter-layer prediction for scalable video coding are disclosed. Embodiments according to the present invention apply inter-layer adaptive filtering to the video data derived from the reconstructed BL video data to generate inter-layer adaptive filtered data. The inter-layer adaptive filtered data is then included as prediction data to encode or decode the EL video data. The video data derived from the reconstructed BL video data is up-sampled before applying inter-layer adaptive filtering. The up-sampling may also be included in the inter-layer adaptive filtering. In another embodiment, the inter-layer adaptive filtering comprises adaptive up-sampling. For up-sampled BL video data at locations not collocated with the EL video data, the up-sampled BL video data is divided into location types according to locations of the up-sampled BL video data. Each location type may have an individual filter for up-sampling video data in the group.

摘要： This disclosure described techniques for coding layer dependencies for a block of video data. According to these techniques, a video encoder generates layer dependencies associated with a given layer. The video encoder also generates a type of prediction associated with one or more of the layer dependencies. In some examples, the video encoder generates a first syntax element to signal layer dependencies and a second syntax element to signal a type of prediction associated with one or more of the layer dependencies. A video decoder may obtain the layer dependencies associated with a given layer and the type of prediction associated with one or more of the layer dependencies.

摘要： View synthesis is performed based on obtained texture data and a depth map. The resolution of the depth map is lower than that of the texture data by a ratio dw in the x direction and by a ratio dh in the y direction. Texture pixel positions x, y are transformed into non-integer depth map pixel positions by performing divisions x/dw and y/dh and these non-integer depth map pixel positions are rounded to integer depth map pixel positions, and a view is synthesized based at least on the obtained texture data and depth map values at the integer depth map pixel positions and/or adjacent positions.
