| Abstract(in English) | This paper proposes an accurate error concealment technique using a Kalman filter. In order to realize the error concealment, the proposed technique regards the intensities in each frames as elements of the state variable of the Kalman filter and designs the following state transition and observation models. First, the state transition model is designed by using motion vectors and represents the video decoding process. Further, the observation model is designed as a new degradation model and enables the Kalman gain to be calculated for the error concealment. Then, the compensation of the estimation results by the state transition becomes feasible. Consequently, by utilizing these new state transition and observation models, the accurate error concealment based on the rule of least squares can be realized. Experimental results show that the proposed technique has better performance than that of the traditional techniques. |
