Paper Abstract

Statistical image processing methods are widely used for analyzing various random processes. One of these methods is the correlation method, which is applicable in the remote sensing for measuring the transport velocity of aerosol fields and determination of their statistical characteristics such as averaged lifetime, size, orientation, etc. In this work, an image data processing technique based on the temporary instabilities method is described, enabling velocity measurements of statistically homogeneous objects. The ability of the proposed technique for accomplishing simultaneous velocity measurements of different inhomogeneities is demonstrated experimentally. The main drift velocity vector is set by the position of the global correlation maximum, wich is obtained for different couples of recorded images.
