摘要： A surgical operation navigation apparatus comprises a medical image storage section that stores three-dimensional information of a subject measured by a medical image diagnosis unit. A modification information storage section modifies and stores the three-dimensional information of the subject based on predicted modification of the subject. A morphological shape measuring instrument measures a three-dimensional morphological shape of the subject. A morphological shape information storage section compares a three-dimensional morphological shape of a subject with three-dimensional information, and selects and outputs three-dimensional information of the subject that is the most analogous to the morphological shape of the subject. A data image generating section generates data image from the selected, outputted three-dimensional information of the subject. An image superimposing section superimposes a data image from the data image generation section and an image of the subject from the surgical operation utensil, and outputs the superimposed image to an image display device.

摘要： A three-dimensional model search method includes a step of producing a plurality of two-dimensional images obtained by observing a three-dimensional model as an object of search from points of view different from one another. In a first value extraction step, the respective feature values of the two-dimensional images are extracted from the plurality of two-dimensional images. In a search key input step, a two-dimensional image as a search key is inputted. In a second extraction step, the feature value is extracted from the two-dimensional image as the search key. In a similarity search step, the feature values extracted in the first and second extraction steps are used to carry out similarity search, and a three-dimensional model which is similar to the search key is outputted.

摘要： An inputting/designating section inputs a multimedia object or designates a multimedia object previously stored in a database. A feature-value-determining section determines the feature value of the input or designated multimedia object. A weighting-factor-determining section determines the determined feature-value weighting factor of the multimedia object. A similarity-retrieval section retrieves the similarity of the multimedia object previously stored in the database by using the determined feature value and the determined feature-value weighting factor. A displaying section displays a multimedia object similar to the multimedia object designated by the inputting/designating section in accordance with the result of similarity retrieval. A similarity-ranking-changing section changes similarity rankings of the displayed multimedia object. A similarity-recalculating section recalculates the feature-value weighting factor of the multimedia object in accordance with the changed similarity ranking and recalculates a similarity by using the feature-value weighting factor.

摘要： An object retrieval method used is characterized as follows. When a user selects objects, the dispersion between the objects is found with respect to each of a plurality of feature quantities. Within a retrieval range of objects, the dispersion between the objects is found with respect to each of a plurality of feature quantities. Both dispersions are compared for each feature quantity. As a result of the comparison, there may be a feature quantity which causes more converged dispersion in the selected objects. This feature quantity is provided with a weight larger than any other feature quantities to weight each feature quantity. An object is retrieved from the retrieval range based on the weighted feature quantities.
