ABSTRACT:
The invention in one embodiment is an apparatus for compressing multi-view video data from a first view and a second view. The apparatus comprises a first encoder receiving a first set of video data from the first view, encoding the first set of video data and transmitting the encoded first set of video data. The apparatus further comprises a second encoder that includes an estimator and a codec. The estimator receives the encoded first set of video data from the first encoder, receives a second set of video data from the second view, generates a pixel-based disparity vector field from the received first and second sets of video data, and transmits the disparity vector field. The codec receives the vector disparity field from the estimator, encodes the received vector disparity vector field with motion compensated disparity, and transmits the encoded disparity vector field.
