Image search system, image search method, and storage medium
First Claim
1. An image search system, comprising:
- a first calculation section that calculates a first similarity score of each registered image with respect to an input image on the basis of image features of the registered image and the input image;
a second calculation section that calculates a second similarity score of each registered image with respect to the input image on the basis of text features of the registered image and the input image;
a candidate extraction section that extracts one or more candidate registered images on the basis of the first and the second similarity scores of each registered image;
a third calculation section that calculates a third similarity score of each candidate registered image on the basis of a comparison of projection waveforms of the input image and the candidate registered image; and
a search section that determines one or more registered images similar to the input image on the basis of the third similarity score of each of registered image.
