A new method for speeding up the integer reversible wavelet transforms constructed by the lifting scheme is proposed. The proposed method packs multiple pixels (wavelet coefficients) in a single word; therefore, it can make use of the 32-bit or 64-bit computational capability of modern computers to accomplish multiple addition/subtraction operations in one instruction cycle. As a result, the proposed method can save the decomposition/reconstruction time by up to 37 percent on 32-bit machines in comparison with the original wavelet transform algorithms. Furthermore, the packed integer wavelet transform requires much less working memory
