5.3.1.1.1JVT-Z029 ( Prop 2.2/3.1) [G. Zhu, X. Xu, P. Yang, Y. He (Tsinghua U.), J. Zheng, X. Zheng (Hisilicon)] MVC inter-view skip mode using depth information
This contribution proposed an inter-view skip mode using depth information. A motion vector (disparity vector) of this mode is derived from the corresponding camera parameters and depth map. Experiments on the one sequence with depth ("Breakdancers") reportedly showed an average benefit of 0.288 dB / 11.37% for the P frame portion of the bitsteam.
No temporal prediction used at all in this test.
Question: What would be the percentage savings of the total bitstream?
Remark: Similar prior investigations have been done.
Remark: Perhaps depth bit rate should be accounted for.
Only tested on P slices. Only applies if (high quality) depth map is available.
Investigation of this feature is reported to only be preliminary.
Contribution noted. This may be a useful area for investigation toward some future project that may include depth map support, but does not seem to be within the scope of the current JVT MVC project.
This contribution was provided to verify the results reported in JVT-Z029. Encoding and decoding results were reportedly verified.
The authors of JVT-Z029 provided their modified source code to the contributor. The encoder and the decoder were compiled to get the results of the proposed scheme of JVT-Z029. And the encoder of anchor was run to get the results of anchor.
The results were reported to be exactly the same as those listed in Table I of JVT-Z029.
5.3.1.1.3JVT-Z048-QV (Late Verif) [H. Yang (Xidian Univ.)] Verif JVT-Z029
This document was provided to verify the results reported in JVT-Z029 from Tsinghua Univ. The software was provided to the contributor for verification, and was reportedly confirmed to match the method described in the proposal. An executable file was generated by compiling the provided software, and was used to decode the provided bitstream. The provided bitstreams were reported to have been successfully decoded, and all results reportedly matched. JVT-Z029 was thus reported to have been verified.
