Antichains: A New Algorithm for Checking Universality of Finite Automata
We propose and evaluate a new algorithm for checking the universality of nondeterministic finite automata. In contrast to the standard algorithm, which uses the subset construction...

A New Method of Image Denoise Using Contourlet Transform
—In all methods of image denoising, there is a problem always exists that is how to distinguish noise and edge. Now wavelet and contourlet are main tools in image denoising, but ...
