Abstract
A method and apparatus for reduction of noise in an image of a sequence of fluoroscopic images of an object in motion having a differentiation of the pixels of the image between pixels in motion and fixed pixels, and a processing wherein a time filtering operation of the fixed pixels. For each pixel of the image, the differentiation between a pixel in motion and a fixed pixel is performed as a function of the result of a detection of motion during which, in a zone of the image covering a set of pixels in the vicinity of the pixel, the existence or respectively the absence of motion of the object relative to a preceding image is detected.
