Abstract :
This paper addresses progressive wavelet image coding within the trellis-coded space-frequency quantization (TCSFQ) framework (Xiong and Wu 1999). A method similar to that in Bilgin et al. (1999) is used to approximately invert TCSFQ when decoding at rates lower than the encoding rate. Our experiments show that the loss incurred for progressive coding is within one dB in PSNR and that the progressive coding performance of TCSFQ is competitive with that of the celebrated SPIHT coder (Said and Pearlman 1996) at all rates
