<P>PROBLEM TO BE SOLVED: To perform image processing based on appropriate image processing conditions by eliminating influences, when the recognition of a structure inside an image has failed or its boundary is not clear. <P>SOLUTION: There is described an image-processing apparatus for applying an image processing to radiographic image data, representing a radiographic image acquired by projecting radial rays penetrated through a subject, so as to obtain an image suitable for diagnosing purpose. The image-processing apparatus includes an edge detecting section to detect an edge of a structural image contained in the radiographic image; a geometrical shape measuring section to measure the degree of a geometrical shape contoured by the edge detected by the edge detecting section; a weight-determining section to determine the weight of the structural image, based on the degree of the geometrical shape measured by the geometrical shape measuring section; and an image-processing section to apply the image processing to the radiographic image data, based on a parameter corresponding to the weight determined by the weight-determining section. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
