Claim One:
1. A method of correcting a digital image obtained using electromagnetic radiation, including X-rays, converted into an electric signal, and transmitted to a digital imaging device, comprising: pyramidal decomposition of the digital image into detailed images and approximation images; removal of scattered radiation in the approximation images to produce processed to approximation images; contrast enhancement of the detailed images to produce processed detailed images; combining the processed detailed images and the processed approximation images; and reconstruction and generation of a final image; and further comprising: before the decomposition, determining a dynamic range of the digital image and correcting amplitude characteristics of the digital image; after the decomposition, determining a signal-to-noise ratio, noise reduction in the detailed images, correcting the detailed images using a frequency characteristic correction coefficient determined by a dynamic range of an output device, a modulation transfer function of a digital imaging device forming the digital image, a set degree of correction of the detailed images, and the signal-to-noise ratio; correcting the detailed images using a correction coefficient and using a brightness of approximation images, and correcting edge artifacts in the detailed images; and after the reconstruction, scaling a dynamic range of the final image using the dynamic range of the digital image, and transmitting the final image to the output device.
