| titleOfInvention | Noisy images sequence processing system and medical examination apparatus including this system |
| abstract | The invention relates to a system for processing a noisy image in a sequence of noisy images, including means for extracting a noisy temporal sample at a given location in the noisy image and for providing a corresponding sample temporally recursively filtered to construct a filtered image of the noise. This system comprises recursive temporal filtering means having means for summing a corresponding sample (Y t-1 ) of a previously filtered previous image of the sequence with a corresponding sample [Δ t (x, y)] an image of the differences (S t -Y t1 ) between the noisy image and the previous filtered image, and weighted by a recursion factor (K t ); two-dimensional spatial filtering means (F 2D ) applied to said image of the differences, in order to enhance spatially coherent samples and provide a measure of probability of movement (β t ) linked to said spatially coherent samples; and means for applying a scalar function (f 1 ) to generate said recursion factor (K t ) depending on said measure of probability of movement (β t ).n n n The invention also relates to an X-ray examination apparatus including such a system. Application : Medical imaging devices |
