Abstract
This paper presents a new, simple, lossless image transform with high speed, high energy compaction and low power for digital image compression. The proposed transform follows the Haar Wavelet Transform (HWT) using the hierarchical structure, with low complexity, prediction based method of computation of the elements instead of the traditional waveforms used with Haar Transform. Energy compaction rate of this Predictive Wavelet Transform is 28% better than HWT after 75% reduction in computations.
