Quantization as Histogram Segmentation: Optimal Scalar Quantizer Design in Network Systems
Abstract--An algorithm for scalar quantizer design on discrete-alphabet sources is proposed. The proposed algorithm can be used to design fixed-rate and entropy-constrained convent...

Fast Index Assignment for Balanced N-Description Scalar Quantization
In this paper, we address the design of any number of balanced descriptions using multiple description scalar quantization(MDSQ), based on fast index assignment. The proposed sche...
