논문 초록 (Abstract)
This paper presents a novel Wyner-Ziv video coding system which is applicable for low-power video surveillance systems in an interactive way. In order to improve the performance of the conventional DVC (Distributed Video Coding) systems for these applications, first, the proposed system evaluates the quality of previously reconstructed Wyner-Ziv frame in a block unit and then, estimates the unreliable blocks of the current Wyner-Ziv frame by exploiting temporal correlation between the previously reconstructed Wyner-Ziv frame and the generated side information. The block location information of the unreliable blocks is provided to the encoder side and thus it enables the encoder to selectively encode the unreliable blocks of the Wyner-Ziv frame. Through several simulations, it is shown that the coding efficiency of the proposed scheme is greatly improved, compared to the conventional DVC scheme.
