On reducing granular distortion in multiple description quantization
Vinay A. Vaishampayan, A.R. Calderbank, J.-C. Batllo · 2002
There is a gap of 3.07 dB between the distortion product of a multiple description quantizer and the multiple description rate distortion bound. In this paper we seek to close this gap through the design of a quantizer with smaller granular distortion.
