摘要： The invention relates to a method of correcting a digital mammogram of a breast containing an implant. According to the invention, brightnesses situated at and around the implant peak (PI) in the low frequency component of the image (XLP) are attenuated (ATT) as compared with a function (P1) that is applied to the other brightnesses, thereby attenuating the implant.The invention also provides a method of segmenting an implant in a radiographic image, the method being characterized by the following steps: smoothing the image by a noise-reducing lowpass filter, applying a non-directional spatial derivative filter, pixel thresholding, and selecting an outline to define the segmented portion of the image that corresponds to the implant.

摘要： A method and apparatus for calibrating an apparatus that acquires a sequence of radiographic images and correcting images of an object under observation. For each image of a sequence acquired by the apparatus and for a given frequency of acquisition of the sequence, the apparatus is calibrated by determining the value of the variation of a mean of gray levels in at least one zone of interest of the current image of at least one calibration device, the variation being determined relative to the mean gray level of the first image of the sequence in each zone of interest. The determination of the variation is reiterated for a series of images sequences acquired using calibration devices resulting in first images of mean gray levels different from one sequence to another. Each image of an image sequence of the object under observation is corrected, comprising zones of observation having different gray levels by subtracting from the current image the variation of one gray level relative to the first image of the object, the subtraction being a function of the gray level considered from each zone of observation.

摘要： Method of improved detection of elements of interest by means of a detection system in a digital radiographic image of an object, acquired on an acquisition chain, comprising a first calibration phase in which the performances of the detection system are established. For such purpose, a calibration curve with several dimensions is determined by means of a mathematical model of the acquisition chain and object, in order to express a false positive probability as a function of a set of parameters corresponding to the acquisition chain and object. In the course of a second phase of use, a false positive probability value is determined for each pixel of the image. One then selects among the pixels of the digital radiographic image acquired those whose probability value obtained satisfies a predetermined criterion.
