We present a biorthogonal wavelet construction for Loop subdivision, based on the lifting scheme. Our wavelet transform uses scaling functions that are recursively defined by Loop...

In this work, kinds of Marr-type wavelets Ψn(t) are obtained and an explicit expression for the wavelets is derived. Time–frequency analysis shows that, regarded as window func...

In this paper, we present preliminary results comparing the nature of the errors introduced by the mixture of principal components (MPC) model with a wavelet transform and the Karh...
