Abstract:
1. An image search system, comprising: a first calculation module 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 module 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 module that supplies the input image to the first calculation module or the second score calculation module, to which of the first calculation module or the second score calculation module is determined based on the amount of text in the input image, and extracts one or more candidate registered images on the basis of the resulting first similarity score or the second similarity score of each registered image; a third calculation module that calculates a third similarity score of each candidate registered image on the basis of projection waveforms of the input image and the candidate registered image; and a search module 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.
