Classification: CPC G | IPC G

Claim 0:
1. A search system comprising:
a server comprising a learner that calculates a feature quantity of a first image that is input and outputs a score of the first image and box information of the first image based on the feature quantity, the score indicating probability that is output by the leamer and the box information indicating a position of a bounding box in the first image; and
at least one processor configured to:
store a feature quantity of the first image to be searched, which has been input in the learner, in a database,
input a second image in the learner; and
search for the first image that is similar to the second image in the feature quantity based on the database;

wherein
the learner includes an intermediate layer, a first output layer, and a second output layer,
the intermediate layer is disposed before the learner branches into the first output layer and the second output layer and calculates the feature quantity,
the first output layer outputs the score based on the feature quantity calculated by the intermediate layer before branching, and
the second output layer outputs the box information based on the feature quantity calculated by the intermediate layer before branching;

wherein the at least one processor searches for the first image that is similar to the second image in the score, and, among a plurality of retrieved first images, searches for the first image that is similar to the second image in the feature quantity; and
the at least one processor searches for the first image that is similar to the second image in the box information among the first image that is similar to the second image in the score, and, among the plurality of retrieved first images, searches for the first image that is similar to the second image in the feature quantity.
