Successively refinable trellis coded quantization

Abstract

We propose successively refinable trellis coded quantizers which are suitable for progressive transmission. A new trellis structure which is scalable is used in the design of our trellis coded quantizers. A hierarchical set partitioning is used to preserve successive refillability. Two algorithms for designing trellis coded quantizers which provide embedded bit streams are provided. The computational complexity of the proposed schemes is compared with that of trellis coded quantization. Simulation results show good performance for memoryless sources.
