In this paper, an improved Laplacian pyramid is proposed. We introduced additional adaptive lifted steps in the Laplacian pyramid. Our pyramid is able to control efficiently the entropy of detail image. Hence, it provides improved coding performance when compared to the standard Laplacian pyramid. Simulation results show that coding gains of up to 1 dB for images when compared to the standard Laplaican pyramid, and the adaptive lifted Laplacian pyramid have significantly lower entropy values.
