Abstract
In this paper, we construct a length-four parameterized tight wavelet frame with three passes based on the design of low pass filter using Sub-QMF. Comparing to the usual methods, it not only keeps some advantages of parameterized tight wavelet frame such as more freedom, good smoothness and symmetries, but also has the least passes. By applying it to the image fusion, we further discovery that it is more effective than Laplacian pyramid, Haar wavelet, and tight frame with four passes.Keywordsparameterized designtight wavelet frameSub-QMFimage fusion
