Definitions

  • the invention relates generally to the Three-Dimensional (3D) video processing.
  • the present invention relates to methods for inter-view residual prediction in 3D video coding.
  • 3D video coding is developed for encoding or decoding video data of multiple views simultaneously captured by several cameras. Since all cameras capture the same scene from different viewpoints, multi-view video data contains a large amount of inter-view redundancy. To share the previously encoded residual information of reference views, an additional tool called inter-view residual prediction has been integrated to the current HEVC based 3D video coding.
  • the inter-view residual prediction is based on a disparity vector derivation for the current block.
  • a disparity vector is firstly derived for a current prediction unit (PU) and then the residual block in a reference view that is referenced by the disparity vector is used for predicting the residual of the current PU.
  • the residual block in the reference view can be the actual coded residual data in the reference view as in current HTM5.0, or can be generated by applying the motion of current block to the corresponding block in the reference view as done in JCT3V- B0051.
  • FIG. 2 A more detailed illustration of the concept for deriving a reference block location inside the reference view is given in Figure 2.
  • a disparity vector is firstly determined for the current PU.
  • the disparity vector is added to the location of the top-left sample of the current PU yielding the location of the top-left sample of the reference block.
  • the block of residual samples in a reference view that is located at the derived reference location is subtracted from the current residual and only the resulting difference signal is transform coded.
  • the reference residual block is generated by applying the motion of current block to the corresponding block in the reference view as done in JCT3V-B0051, then the computational complexity will be very high since the interpolation during the motion compensation in both reference view and current view.
  • the simplified interpolation will be used for motion compensation when the reference residual block is generated by applying the motion of current block to the corresponding block in the reference view as done in JCT3V-B0051.
  • Fig. 1 is a diagram illustrating the basic concept for inter- view residual prediction
  • Fig. 2 is a diagram illustrating the derivation of the location of reference residual block.
  • the motion information will be inherited from the reference spatial neighbouring block to the current block. It is proposed that the IVRP information is also inherited as the motion information. That is to say, if the reference spatial neighbouring block uses IVRP, then current PU will also use the IVRP and the DV (disparity vector) used for IVRP will be the same as that of the reference spatial neighbouring block.
  • IVRP information is also inherited. That is to say, if the reference co-located texture block uses IVRP, then current PU (depth block) also uses the IVRP and the DV used for IVRP will be the same as that of the reference co-located texture block.
  • the motion vectors of this PU are rounded to the nearest integer positions first and then these rounded motion vectors are applied to the corresponding block in the reference view to generate the reference residual block to avoid the interpolation during motion compensation.
  • an embodiment of the present invention can be a circuit integrated into a video compression chip or program codes integrated into video compression software to perform the processing described herein.
  • An embodiment of the present invention may also be program codes to be executed on a Digital Signal Processor (DSP) to perform the processing described herein.
  • DSP Digital Signal Processor
  • the invention may also involve a number of functions to be performed by a computer processor, a digital signal processor, a microprocessor, or field programmable gate array (FPGA).
  • processors can be configured to perform particular tasks according to the invention, by executing machine- readable software code or firmware code that defines the particular methods embodied by the invention.
  • the software code or firmware codes may be developed in different programming languages and different format or style.
  • the software code may also be compiled for different target platform.
  • different code formats, styles and languages of software codes and other means of configuring code to perform the tasks in accordance with the invention will not depart from the spirit and scope of the invention.
