Lifting dual tree complex wavelets transform

Abstract: We describe the lifting dual tree complex wavelet transform (LDTCWT), a type of lifting wavelets remodeling that produce complex coefficients by employing a dual tree of lifting wavelets filters to get its real part and imaginary part. Permits the remodel to produce approximate shift invariance, directionally selective filters and reduces the computation time (properties lacking within the classical wavelets transform). We describe a way to estimate the accuracy of this approximation and style appropriate filt… Show more

“…The initial signal is not decimated by UWT. Instead of down sampling the signal after applying low pass or high pass filters, it modifies the filters at each level by padding with zeros [21]. When compared to classical wavelets, the UWT sub signals from the analysis have the same size as the original signal.…”
