INFORMATION PROCESSING DEVICE, PROCESSING METHOD AND COMPUTER-READABLE STORAGE MEDIUM Russian patent published in 2013 - IPC G06F17/00 

FIELD: information technology.

SUBSTANCE: information processing device has a spatial filtering means for performing spatial filtering in a frequency range based on a spatial frequency of an object for image data of a current frame; and a recursive filtering means for performing recursive filtering by obtaining image data, which have been processed prior to the current frame, from a memory device, multiplying the obtained image data by a coefficient α (α < 1), adding the image data multiplied by the coefficient α to the image data of the current frame after the spatial filtering, and storing the image data after addition in the memory device.

EFFECT: broader functional capabilities of image processing by ensuring noise reduction, thereby suppressing the effect of radiation on the object.
