ABSTRACT:
TCQ has been shown to be an effective method for quantization in image
compression algorithms.  To support emerging image communication applications
such as digital libraries, teleconferencing and remote sensing, the ability to
progressively decode compressed imagery is desirable.  In this paper, we
describe an entropy coder that enables progressive decoding -- by pixel
resolution or by pixel accuracy -- of wavelet transformed and trellis coded
quantized imagery.   The progressive decoding capabilities are provided with
no loss in coding efficiency.
