Abstract

A non-transitory recording medium storing a program that causes a computer to execute a process, the process includes: imaging a given object from plural different angles, and extracting from the plural obtained captured images, one or plural captured images having a feature amount that differs from a feature amount in another captured image by more than a specific reference amount; and providing the one or the plural extracted captured images as determination-use images employable in determination as to whether or not the given object is included in a captured image.

First claim

What is claimed is:

1 . A non-transitory recording medium storing a program that causes a computer to execute a process, the process comprising:
extracting, from a plurality of captured images obtained by imaging a given object from a plurality of different angles, one or more captured images having a feature amount that differs by more than a specific reference amount from feature amounts of the other captured images; and providing the extracted one or more captured images as one or more determination-use images employable to determine whether or not the given object is included in a captured image.

2 . A non-transitory recording medium storing a program that causes a computer to execute a process, the process comprising:
from a plurality of captured images obtained by imaging a given object from a plurality of different angles, extracting and storing, in a memory, one or more captured images having a feature amount that differs by more than a specific reference amount from feature amounts of the other captured images; and comparing a feature amount of a captured image other than the plurality of captured images against the feature amount of the one or more captured images stored in the memory; and determining whether or not the given object is included in the captured image other than the plurality of captured images based on a comparison result.

3 . The non-transitory recording medium of claim 2 , wherein the captured image other than the plurality of captured images is an image acquired through the Internet.

4 . The non-transitory recording medium of claim 2 , wherein the process further comprises:
identifying a provision source of the captured image other than the plurality of captured images in which the given object has been determined to be included; and outputting a message to the identified provision source.

5 . The non-transitory recording medium of claim 4 , wherein the process further comprises:
outputting information that identifies the provision source of the captured image other than the plurality of captured images in which the given object has been determined to be included as a result of the determination.

6 . The non-transitory recording medium of claim 1 , wherein the process further comprises:
from among the plurality of captured images obtained by imaging from a plurality of different angles, setting a reference captured image as a reference, and extracting a captured image in which a difference from a feature amount of the reference captured image is more than the specific reference amount; and setting the extracted captured image as a new reference captured image, and further extracting a captured image in which a difference from a feature amount of the new reference captured image is more than the specific reference amount.

7 . The non-transitory recording medium of claim 1 , wherein the process further comprises:
categorizing the plurality of captured images obtained by imaging from a plurality of different angles into a plurality of classes such that typical vectors of each of the classes differ by more than the specific reference amount from each other; and extracting one captured image from each class in the plurality of classes.

8 . The non-transitory recording medium of claim 1 , wherein the plurality of captured images obtained by imaging from a plurality of different angles are each captured images in which a background behind the given object has been eliminated.

9 . A service provision method, comprising:
by a processor, extracting, from a plurality of captured images obtained by imaging a given object from a plurality of different angles, one or more captured images having a feature amount that differs by more than a specific reference amount from feature amounts of the other captured images; and by the processor, providing the extracted one or more captured images as one or more determination-use images employable to determine whether or not the given object is included in a captured image.

10 . The service provision method of claim 9 , wherein:
by the processor, a reference captured image is set as a reference from among the plurality of captured images obtained by imaging from a plurality of different angles, and a captured image is extracted in which a difference from a feature amount of the reference captured image is more than the specific reference amount; and by the processor, the extracted captured image is set as a new reference captured image, and a captured image in which a difference from a feature amount of the new reference captured image is more than the specific reference amount is further extracted.

11 . The service provision method of claim 9 , wherein:
by the processor, the plurality of captured images obtained by imaging from a plurality of different angles are categorized into a plurality of classes such that typical vectors of each of the classes differ by more than the specific reference amount from each other; and by the processor, one captured image is extracted from each class in the plurality of classes.

12 . The service provision method of claim 9 , wherein the plurality of captured images obtained by imaging from a plurality of different angles are each captured images in which a background behind the given object has been eliminated.
