Generalized Pareto Distributions - Application to Autofocus in Automated Microscopy.
IEEE Journal of Selected Topics in Signal Processing(2016)
摘要
Dihedral filters correspond to the Fourier transform of functions defined on square grids. For gray value images there are six pairs of dihedral edge-detector pairs on 5 ×5 windows. In low-level image statistics the Weibull- or the generalized extreme value distributions are often used as statistical distributions modeling such filter results. Since only points with high filter magnitudes are of i...
