In this work we introduce a new frequency warping operator for non-smooth warping function allowing perfect reconstruction. The transformation is based on a previously introduced aliasing compensated frequency warping operator having a residual error because of finite output dimension. By adding some redundancy, the effect of an infinite output dimension can be taken into account in a compressed way, based on an analytical factorization. In the reconstruction process, the additional redundant samples are expanded, making the inverse transform differ from the direct one, but guaranteeing perfect reconstruction. |
