Abstract
A method for image processing comprising filtration and conversion to a radiometric color image based on an original image. The method gives the processed image high spatial resolution combined with high dynamic resolution. The original image is made available in digital format. Contrast-increasing filtration is performed on the original digital image. The original digital image is converted into a radiometric pseudocolor image based on a chosen color range in which each color corresponds to an absolute measured, radiated or reflected quantity of energy within a certain wavelength band and where the images are represented in a format containing a luminance component. The filtered contrast-increased original image is scaled in terms of the luminance component in the radiometric color image. The luminance component in the radiometric color image is replaced with the scaled, filtered contrast-increased luminance component of the original image.
