3d video coding including depth based disparity vector calibration

A computer-implemented method for video coding, comprising:

• calibrating two or more disparity vectors associated with a prediction unit based at least in part on a depth map, wherein the prediction unit corresponds to a portion of a video picture that is associated with the depth map;
• performing disparity compensated inter-picture prediction on the prediction unit based at least in part on the calibrated disparity vectors;
• and
• coding the prediction unit based at least in part on the disparity compensated inter-picture prediction.

A system for video coding on a computer, comprising:

• a display device configured to present video data;
• one or more processors communicatively coupled to the display device;
• one or more memory stores communicatively coupled to the one or more processors;
• a calibration logic module communicatively coupled to the one or more processors and configured to calibrate two or more disparity vectors associated with a prediction unit based at least in part on a depth map, wherein the prediction unit corresponds to a portion of a video picture that is associated with the depth map;
• a disparity compensation logic module communicatively coupled to the calibration logic module and configured to perform disparity compensated inter-picture prediction on the prediction unit based at least in part on the calibrated disparity vectors;
• and
• a coder communicatively coupled to the disparity compensation logic module and configured to code the prediction unit based at least in part on the disparity compensated inter-picture prediction for presentation on display device.
