An efficient depth map estimation technique using complex wavelets
A new focus measure system is proposed based on complex wavelet transform and quadrature pair of steerable filters. In shape from focus (SFF), noise, illumination variation and or...

Image reconstruction from a complete set of similarity invariants extracted from complex moments
Various types of moments have been used to recognize image patterns in a number of applications. However, only few works have paid attention to the completeness property of the in...

The impact of higher-order state and control effects on local relational reasoning
Reasoning about program equivalence is one of the oldest problems in semantics. In recent years, useful techniques have been developed, based on bisimulations and logical relation...
