Abstract: Discussed is an image processing method and device. An image processing method according to an embodiment can include obtaining an X-ray image, converting the obtained X-ray image into a frequency domain, detecting peak shape information from the converted X-ray image in the frequency domain, selecting a peak candidate region based on detected the peak shape information, determining whether each selected peak candidate region is a grid peak and generating a peak map, filtering the converted X-ray image based on the generated peak map, converting the filtered X-ray image in the frequency domain into a spatial domain, and providing a domain converted X-ray image in the spatial domain.

Abstract: An X-ray image processing device can include an image analyzer configured to analyze a received original X-ray image; a converter configured to convert the original X-ray image into a multi-scale transformed X-ray image based on analysis results and separate the converted X-ray image into a plurality of layers in frequency units; a noise predictor configured to generate a noise prediction map by enhancing and combining specific frequency portions of the plurality of layers; an edge map processor configured to generate an edge map based on the generated noise prediction map; a contrast processor configured to enhance a contrast of the converted X-ray image based on the generated edge map; an inverse converter configured to perform a flattening process and an edge correction process on the contrast-enhanced X-ray image and perform an inverse conversion to the contrast-enhanced X-ray image; and a controller configured to perform a tone-mapping operation.
