摘要

To meet the requirements of resource-limited video sensors, low-complexity video encoding technique is highly desired. In this paper, a low-complexity multi-view distributed video encoding scheme by using the correlations among video frames from adjacent video sensor nodes (VSNs) via robust media hashing at encoder and the global motion parameters estimated and fed back from the decoder is proposed. The frames from adjacent VSNs are warped into the same view-direction based on the global motion parameters. Then, the significant differences between the warped key frame and the non-key frame from adjacent VSNs are efficiently extracted based on robust media hashing for non-key frame compression. The key is that few data (hash information) exchanges among adjacent VSNs are allowed to efficiently exploit the correlations among VSNs. The coding performance and energy consumption of the proposed encoder have been verified through simulations and comparisons with existing low-complexity video encoders.
