Abstract
The lifting transform reduces the number of lifting steps in lossless data compression while improving the overall rounding errors incurred in the real-to-integer conversion process at each of the lifting steps. The compression ratio increases when used for lossless image data compression. The lifting transform further saves memory space and decreases signal delay.
