Methodology for numerical assessments of the quality of cloud fields images used in time mutability method

The methodology described below supports the time mutability method for estimating cloud drift velocity. A technique for determination numerical values of the contrast and impulse noise level in images of cloud fields is presented. The contrast for the entire image and the level of the impulse noise for the entire image and in addition -in angular directions have been calculated in accordance with the method for drift velocity estimation. The evaluations have been realized by special developed software modules.
