Two-Dimensional Wiener Filters for Error Resilient Time Domain Lapped Transform

Jie Liang, Xin Li, Guoqian Sun, T.D. Tran
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings  
This paper presents the design of two-dimensional Wiener filters for error resilient time domain lapped transform.  ...  Design examples and image coding experiments show that the adaptive 2-D Wiener filters provide significant improvement over the existing 1-D Wiener filtering method.  ...  CONCLUSIONS Two-dimensional Wiener filter for the error resilient lapped transform is developed.  ...
