Progressive image coding using trellis-coded space-frequency quantization
Pierre Seigneurbieux, Zixiang Xiong · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2001
This paper addresses progressive wavelet image coding within the trellis-coded space-frequency quantization (TCSFQ) framework. A method similar to that in [2] is used to approximately invert TCSFQ when decoding at rates lower than the encoding rate. Our experiments show that the loss incurred for progressive transmission is within one dB in PSNR and that the progressive coding performance of TCSFQ is competitive with that of the celebrated SPIHT coder at all rates.
