IMAGE EXTRACTION SYSTEM, IMAGE EXTRACTION METHOD, IMAGE EXTRACTION PROGRAM, AND RECORDING MEDIUM STORING PROGRAM

摘要

There are provided an image extraction system, an image extraction method, and an image extraction program for extracting images valuable to a user and a recording medium storing the program. An image set including three or more images is classified into a plurality of clusters, and an annotation indicating a subject or a scene of each image is acquired from a plurality of images included in each cluster. Image co-occurrence probabilities in a plurality of images are calculated from the acquired annotations, and an image with an image co-occurrence probability equal to or less than a threshold value is extracted.

主权项

1. An image extraction system, comprising:
an annotation acquisition unit that acquires annotations, which are information specifying at least one of a subject present in each image or a scene of each image, from a plurality of images; an image co-occurrence probability calculation unit that calculates an image co-occurrence probability, which indicates a frequency of occurrence of at least one of a subject or a scene in each of the plurality of images, from the annotations of the images acquired by the annotation acquisition unit; and a first image extraction unit that extracts an image, the image co-occurrence probability of which is equal to or less than a threshold value, from the plurality of images.
