MEMORY CONSTRAINED WAVELET-BASED IMAGE-CODING

We present a method for ordering the wavelet coefficient information i n a compressed bitstream that allows an image to be sequentially decod ed, with lower memory requirements than conventional wavelet decompres sion schemes. We also introduce a hybrid filtering scheme that uses di fferent horizontal and vertical filters, each with different depths of wavelet decomposition. This reduces decoder memory requirements by re ducing the instantaneous number of wavelet coefficients needed fbr inv erse filtering.
