Abstract
An image retrieval system includes an obtaining unit that obtains a query image, a specifying information extracting unit that extracts, from the query image, specifying information which specifies an image group as a retrieval target, a feature information extracting unit that extracts, from the query image, feature information to be used in image retrieval processing, and a retrieval unit that performs the image retrieval processing on retrieval target images specified by the specifying information, using the feature information.
Claims11
An image retrieval system comprising:
- at least one processor configured to execute computer executable instructions, the computer executable instructions causing the at least one processor to implement:
- an obtaining unit configured to obtain a query image;
- a specifying information extracting unit configured to extract, from the query image, specifying information comprising a watermark which specifies retrieval target images;
- a feature information extracting unit configured to extract, from the query image, feature information to be used in image retrieval processing;
- and
- a retrieval unit configured to perform the image retrieval processing on retrieval target images specified by the specifying information, using the feature information.
An information processing apparatus for use in an image retrieval system, wherein the image retrieval system includes an obtaining unit that obtains a query image, a specifying information extracting unit that extracts, from the query image, specifying information comprising a watermark which specifies retrieval target images, a feature information extracting unit that extracts, from the query image, feature information to be used in image retrieval processing, and a retrieval unit that performs the image retrieval processing on retrieval target images specified by the specifying information, using the feature information, the information processing apparatus comprising:
- the specifying information extracting unit.
An image retrieval method comprising:
- obtaining a query image;
- extracting, from the query image, specifying information comprising a watermark which specifies retrieval target images;
- extracting, from the query image, feature information to be used in image retrieval processing;
- and
- performing the image retrieval processing on retrieval target images specified by the specifying information, using the feature information.
A non-transitory computer readable medium storing a program causing a computer serving as an information processing apparatus in an image retrieval system to function as a specifying information extracting unit, the program causing the computer to perform:
- obtaining a query image;
- extracting, from the query image, specifying information comprising a watermark which specifies retrieval target images;
- extracting, from the query image, feature information to be used in image retrieval processing;
- and
- performing the image retrieval processing on retrieval target images specified by the specifying information, using the feature information.
