Minimum-energy wavelet frame on the interval with arbitrary integer dilation factor

摘要

In this paper, we study minimum-energy frame Ψ={ψ1,ψ2,…,ψM} on the interval with arbitrary factor d for L2[0,1], Ψ corresponding to some refinable functions with compact support. We give the constructive proof as well as the necessary and sufficient conditions of minimum-energy frames for L2[0,1], present the decomposition and reconstruction formulas of minimum-energy frame on the interval [0,1], and some examples. The experimental results show that the proposed minimum-energy frame on the interval improves the performance in the application of image denoising significantly.
