Shannon Wavelet Analysis [PDF]
, 2007 In this paper the differentiable structure of the Shannon wavelets is defined and the projection of a linear differential operators is given for any order. As application, the wavelet solution of a heat propagation problem is computed and the contribution of the different scale components is explicitly shown.

Fringe pattern analysis using a one-dimensional modified Morlet continuous wavelet transform [PDF]
, 2008 This paper proposes the use of a modified Morlet wavelet in order to demodulate fringe patterns in conjunction with the one-dimensional continuous wavelet transform (1D-CWT). Our investigations demonstrate that the modified Morlet wavelet produces better
