Method for processing digital images captured by satellite, comprises application of fractal modelling to Fourier transforms of image pixels and similarity test to starting transforms

摘要

A Fourier transform (12) is applied to image pixels (10) and the resultant coefficients (14) and fractal coefficients (26,18) are used (16) by a fractal model (M) . A modelling (28) of the modulation function of the instrument (FTM) and associated noise (N) may be included.. The modelled Fourier coefficients (20) are compared for maximum similarity (22) to the original transforms to find key parameters (24,30) required for image enhancement
