摘要： A method for determining a contour of an object in a digital image includes determining a preliminary object center and determining contour candidate image points. The contour candidate image points are determined as image points on a plurality of paths leading away from a preliminary object center by detecting a change from a first section to a second section on a feature space based on the image point value range of the digital image or by detecting the exceeding of a predetermined strength of a feature change in the feature space, wherein the contour candidate image points have a distance to the preliminary or to an improved object center and are ordered according to a polar angle. Further, the method includes determining zones of neighboring contour candidate image points within which a change of the distance of the contour candidate image points lies above a threshold value and an elimination of contour candidate image points which lie between the zones of neighboring contour candidate image points. Finally, a determination of the contour is executed on the basis of the remaining contour candidate image points.

摘要： In a method for calibrating a stage-camera system, a travel distance of a stage is determined in a first coordinate system and an object displacement distance of at least one object is determined in a second coordinate system. A calibration measure for calibrating the coordinate systems is computed from the travel distance and the object displacement distance. The object displacement distance is determined by registering a calibration image with a reference image based on the at least one object. The method enables an automatic and accurate calibration of the stage-camera system.

摘要： Apparatus for segmenting microcalcifications in a mammographic image having a bandpass filter for bandpass filtering the mammographic image obtaining the filtered mammographic image, a marker and a processor for individual processing. The marker marks image points in the filtered mammographic image as potential regions of microcalcifications when a they exceed or fall below a predetermined threshold. The processor for individual processing processes one of the regions of adjacent marked image points for changing an extension of the one region for illustrating a segmentation of microcalcifications.
