| titleOfInvention | Multidimensional noisy image processing method and medical imaging apparatus using this method |
| abstract | The invention relates to an image processing method for preserving the edges of objects represented in an intensity image and for reducing noise, comprising steps of acquiring the intensity image in the form of a matrix. multidimensional of points (2-D, 3-D), for determining the intensity gradient at each point, defined by its direction ( p) and its modulus (∥ G p ∥), and passing at each point a recursive spatial filter with an anisotropic nucleus causing a greater degree of smoothing perpendicular to the direction of the gradient than in the direction of the intensity gradient. The nucleus is spherical on non-normal scanning lines with intensity gradient and this nucleus is a flattened sphere, the largest dimension of which is on normal lines with intensity gradient at a scanned point. The invention also relates to an X-ray medical imaging device implementing this method. |
