WebPySptools is a python module that implements spectral and hyperspectral algorithms. Specializations of the library are the endmembers extraction, unmixing process, supervised classification, target detection, noise reduction, convex hull removal and features extraction at spectrum level. The library is designed to be easy to use and almost all ... WebThe Minimum Noise Fraction (MNF) transform (Green et al, 1988) is an algorithm consisting of two consecutive data reduction operations. The first is based on an estimation of noise in the data as represented by a correlation matrix. This transformation decorrelates and rescales the noise in the data, by variance.
