Distributed video coding (DVC) is considered as one promising video coding scheme for Wireless Video Sensor Network (WVSN) due to its high compression efficiency and error resilience functionalities, as well as the low encoding complexity. In this paper, an improved DVC scheme based on checkerboard pattern splitting for Wyner-Ziv (WZ) frame is presented. In specific, the modified three-dimensional...
The side information (SI) generation is a key function in the Wyner-Ziv (WZ) video coding, which plays an important role in determining the performance of the codec. This paper proposes an improved SI generation scheme for wavelet transform based WZ video codec. In specific, we adopt the motion estimation with Kalman filter, by which an optimal estimation of motion vector can be achieved. Simulation...
