Title: | Updating mixture of principal components for error concealment | Authors: | Chen T.P.-C. Chen T. |
Issue Date: | 2002 | Citation: | Chen T.P.-C., Chen T. (2002). Updating mixture of principal components for error concealment. IEEE International Conference on Image Processing 2 : II/697-II/700. ScholarBank@NUS Repository. | Abstract: | In this paper, we present a new statistical modeling technique called "updating mixture of principal components" (UMPC). UMPC specifically captures the non-stationary as well as the multi-modal characteristics of the data. Real-world data such as video data typically have these two characteristics. The video content changes over time and has a multi-modal probability distribution. We apply UMPC to perform error concealment for video data transmitted over networks with losses, and show that UMPC outperforms conventional error concealment methods. | Source Title: | IEEE International Conference on Image Processing | URI: | http://scholarbank.nus.edu.sg/handle/10635/146368 |
