Abstract:
1. An object retrieval method comprising: a first step of selecting a plurality of objects from displayed objects; a second step of obtaining dispersions of the selected plurality of the objects with respect to a plurality of different types of feature quantities; a third step of obtaining dispersions of a plurality of objects in a range from which a plurality of objects are selected with respect to the plurality of different types of feature quantities; a fourth step of comparing the dispersions obtained in the second step with the dispersions obtained in the third step for each of the plurality of different types of feature quantities; a fifth step of weighting each of the plurality of the different types of feature quantities through a quantitative calculation using the dispersions obtained in the second step and the dispersions obtained in the third step so that, a weight given to a feature quantity which dispersion obtained in the second step is more converged than the corresponding dispersion obtained in the third step is larger than a weight given to a feature quantity which dispersion obtained in the second step is not more converged than the corresponding dispersion obtained in the third step; and a sixth step of retrieving objects in the range of object retrieval by using the plurality of the different types of features weighted in the fifth step.
