Processes and correction devices of a mammography implant and segmentation of an implant

The invention relates to a method for correcting a digital mammogram of a breast implant containing a. According to the invention, is applied to the low frequency image component (XLP), an attenuation (ATT) implant for the light intensities located in and around the peak (PI) of implant with respect to the function (P1) applied to the other lumineuses.L'invention intensities also relates to a method for segmenting an implant into a radiographic image, characterized by the steps of: smoothing the image with a lowpass filter noise reduction, app a non-directional spatial branching filter, thresholding of pixels, selecting a contour to define the segmented portion of the image corresponding to the implant.
