ABSTRACT:
An adaptive lifting transform provides lossless image data compression on an improved edge prediction process. The adaptive predictor works on pixel-by-pixel basis that does not need bookkeeping overhead, especially for integer-to-integer wavelet transform for reducing the number of lifting steps for use in JPEG2000 image compression.
