High-order statistics of 2D distributions of the Stokes parameters of biological tissue images

摘要

Polarization structure of the speckle-images of connective tissues histological sections in the terms of two-dimensional distributions of the Stokes vectors parameters is analyzed. Statistical moments of the Stokes vector parameters of the first-fours orders and autocorrelation functions of the speckle-images of physiologically normal and pathologically changed connective tissue are analytically and theoretically investigated. The totality of statistical (mean value, dispersion, skewness and kurtosis) parameters of two-dimensional distributions of the Stokes vector parameters and their autocorrelation functions and the dispersion of power spectrum are found. The latter can be used during the early diagnostics of connective tissues pre-cancer states.
