摘要： An object of the present invention is to provide the technology capable of appropriately balancing the preciseness of contour extraction and calculation cost. In order to achieve this object, an energy function setting section sets an energy function that is expressed by a weighted linear sum of a plurality of kinds of energy terms defined correspondingly to a state of an active curve and is formulated so as to have a smaller value as approaching a shape of the contour to be extracted, and an iterative computation processing section minimizes the energy function by an iterative computation. An end instruction section sets an auxiliary function formulated so as to monotonously increase in accordance with the number of iteration times of iterative computation and sets a judging function expressed by a linear sum of the auxiliary function and the energy function. Then, a point of time when a local minimum appears in the judging function in the course of the iterative computation is judged as the end timing of iterative computing.

摘要： A virtual plane of projection on which a virtual three-dimensional object constructed by a set of specific structures oriented in predetermined directions is projected is set. First, while generating a basic image by projecting one specific structure oriented in a predetermined direction onto the virtual plane of projection, a reference image position corresponding to a reference position of the one specific structure in the basic image is recognized. At the time of projecting a virtual three-dimensional object onto the virtual plane of projection, each of reference projection positions in which the reference positions of specific structures constructing the virtual three-dimensional object are projected is detected. Further, by combining adjusted basic images generated by adjusting the positions of the basic images relative to the virtual plane of projection in accordance with the reference projection positions, a display image is generated.

摘要： The present invention proposes a technique capable of accurately grasping position and angle of a radiation generator at the time of image capturing. At the time of obtaining a plurality of transmission images by detecting radiation emitted from a emitting generator and passing through a specimen via a predetermined member (for example, a diaphragm) by a detector for a plurality of times while changing a relative position relation and a relative angle relation of the emitting generator to the detector, an outer-edge shape of a radiation area irradiated with the radiation on a detection surface of the detector from the emitting generator is recognized. On the basis of the outer-edge shape of the radiation area and an inner-edge shape of a predetermined member, the relative position relation and the relative angle relation of the emitting generator to the detector are obtained.

摘要： A corresponding point candidate determiner (108) determines whether plural correlation peaks appear, based on a correlation value calculated by a corresponding point determiner (107). In the case where the corresponding point candidate determiner (108) determines that plural correlation peaks appear, the corresponding point determiner (107) calculates a ratio between the correlation values as represented by the correlation peaks, determines one or more corresponding points, based on the calculated ratio, and notifies the determination result to an initial position setter (106). In the case where the corresponding point determiner (107) searches plural corresponding points, the initial position setter (106) sets an initial search position with respect to each of the corresponding points in a reference image of a layer immediately higher than a target layer.
