摘要： The stereotaxic images being digitized, a target pixel in a target region of interest is selected, a target window of chosen dimensional characteristics and containing the said target region of interest is generated around the selected target pixel, a set of pixels is determined in a second image, according to a predetermined selection criterion, a second window, of the same dimensional characteristics as the said target window, is generated around each selected pixel, a correlation processing between the grey-scale levels of the pixels of each second window and the grey-scale levels of the pixels of the target window is carried out so as to obtain a correlation value for each second window, and the region of interest homologous to the target region of interest is identified on the basis of the analysis of the set of correlation values thus obtained, so as to minimize the risks of matching error between the homologous regions of interest. The element of interest is then located on the basis of the positions of the two homologous regions.

摘要： A process is disclosed which involves automatic position-finding for a point of interest of an object that exhibits high contrast as compared with surrounding tissues, the process being carried out by means of a stereotactic photographic device that includes a digital image acquisition system. The process includes a number of steps for each image belonging to the pair of stereotactic images. An initial analysis of a histogram of the image pixels are made, and a subsequent determination is made of a threshold corresponding to the difference between the high contrast objects and the surrounding tissues. A subsequent determination is made of the threshold of the image, in order to obtain a binary image incorporating two gray levels. This is followed by the filtering of the threshold determined image in the preceding step, based on morphological criteria of the object in which the point of interest is located. This operation is designed to obtain a segmented projection of the object of interest. This is followed by the localization of the point of interest in the image reference mark. Utilization of the process is for stereotactic examinations performed during mammography.

摘要： In order to analyze an image, a search is made, for all the minima of the image, for the dynamic of these minima. When the dynamic of these minima is small it corresponds finally to noise. If this measured dynamic is large, the minimum is regarded as being representative of a sufficiently significant irregularity in the image signal.

摘要： To carry out an automatic processing operation on radiographic images in mammography, it is shown that it is possible to correct the harmful effects of the linearity defect of the characteristic curve of sensitivity of the radiographic film used for this radiograph by making a statistical study of the noise in this image. It is shown that this statistical study enables the correction elements to be deduced directly using a top hat transformation. The processing is then independent of any prior knowledge that might be had of the sensitivity of the film or of the conditions in which the examined radiographs were acquired as well as subsequently developed.
