In the last decade, the research on iris biometric has received increasing attention. Most of this research targets the iris recognition scenarios in constrained or controlled conditions, where considering the unconstrained environments is still needs more research work. In unconstrained environments, the sources of noise in eye regions are signifi...

The Slantlet transform (SLT) is a set of parallel filters, which are originally an orthogonal discrete wavelet transform (DWT). The SLT is recently a method to improve some properties of DWT, such as time localization. In this paper, a complexity reduction of SLT is proposed by reducing the mathematical computations of SLT filters based on the meth...
