A signal-dependent wavelet transform based on the lifting scheme is proposed. The transform can be made reversible (i.e. an integer-to-integer transform). The reversible transform, followed by arithmetic coding, is applied to lossless image compression. Simulation results indicate that the proposed method is superior to the S+P method
