Abstract: The method for correction of a digital image acquired with the use of electromagnetic radiation including X-rays, converted into electric signal and sent to digital imaging device, is provided, comprising pyramidal decomposition of a digital image into detailed and approximation images, removal of scattered radiation in approximation part of the images, contrast enhancement in detailed part of the images, merging of processed detailed and approximation images, the following reconstruction and generation of the final image. The results of the embodiment of this method comprise removal (reduction) of the scattered radiation component, noise reduction, correction of the dynamic range of the output image in accordance with the dynamic range of the output device, and scaling of the dynamic range of the output image in accordance with the dynamic range of the original image.

Abstract: The invention relates to the field of digital image processing and can find use in suppression of noise in digital images, formed by high-energy radiation, including X-ray radiation. Specifically, the invention relates to a method for suppression of noise in digital x-ray images. The objective of the invention is to provide a method for noise suppression in digital X-ray images that has extended functionality, specifically, a method that makes it possible to reduce residual noise level and amount of artifacts in the form of discontinuities, directed along local orientation of object borders in textured image areas, to reduce residual LF noise level, and to eliminate over-smoothing (excessive filtering) of fine details. The technical innovation achieved is the improvement of digital image processing quality.
