摘要：A method for image processing comprising filtration and conversion to aradiometric color image based on an original image. The method gives the processedimage high spatial resolution combined with high dynamic resolution. The original image

is made available in digital format. Contrast-increasing filtration is performed on theoriginal 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 anabsolute measured, radiated or reflected quantity of energy within a certain wavelengthband and where the images are represented in a format containing a luminancecomponent. The filtered contrast-increased original image is scaled in terms of theluminance component in the radiometric color image. The luminance component in theradiometric color image is replaced with the scaled, filtered contrast-increased luminancecomponent of the original image.
