| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose a new method to control signal redundancy by frame expansion for multiple description coding. A conventional method is to partition coefficients of Discrete Wavelet Transform (DWT) using Lattice in the frequency domain. Redundancy is introduced by distance of the wavelet coefficients based on spatial redundancy in the transform domain of the signal. Proposed method introduces redundancy to wavelet coefficients by frame expansion. Experimental results show that proposed method enhances the error resilience of image transmission under packet loss when compared to the conventional method. | |
