Abstract
An image processing apparatus is configured to perform noise reduction on an image obtained by radiography in a recursive way includes: an image input unit receiving frame-by-frame images obtained by the radiography; a motion detection image generating unit configured to generate a motion detection image comprising motion detection information for each pixel of a subtraction image obtained by a subtraction of a current frame image and a previous frame image; a motion probability image generating unit configured to generate a motion probability image based on the generated motion detection image and the motion detection image accumulated up to a previous frame; and an output image generating unit configured to generate an output image of a current frame by mixing the current frame image and the output image of the previous frame based on the motion probability image.
