  • Abstract
    The distribution of edge values for an image of a general scene often has a sharp peak with a long tail. This property, which can be well described by a Lorentzian probability function, has been used to introduce a correction term that reduces the ringing artifacts that are associated with the Poisson MAP superresolution methods.<>
