RELIABILITY ACQUIRING APPARATUS, RELIABILITY ACQUIRING METHOD, AND RELIABILITY ACQUIRING PROGRAM
First Claim
1. A reliability acquiring apparatus comprising:
- a classifier storing section that stores information on a classifier that outputs part likelihood concerning a predetermined part of a detection target when applied to an image;
a part likelihood acquiring section that calculates, concerning an image region included in an input image, the part likelihood on the basis of the information on the classifier;
a part position determining section that determines, on the basis of the calculated part likelihood, a position of the predetermined part in the input image;
a reference position information storing section that stores information on a reference position of the predetermined part;
a difference acquiring section that calculates, on the basis of the information on the reference position, difference information between the reference position of the predetermined part and the determined position of the predetermined part; and
a reliability acquiring section that calculates, on the basis of the difference information, reliability indicating possibility that the input image is an image of the detection target.

Abstract
A reliability acquiring apparatus includes a section that stores information on a classifier that outputs part likelihood concerning a predetermined part of a detection target when applied to an image, a section that calculates, concerning an image region included in an input image, the part likelihood on the basis of the information on the classifier, a section that determines, on the basis of the calculated part likelihood, a position of the predetermined part in the input image, a section that stores information on a reference position of the predetermined part, a section that calculates, on the basis of the information on the reference position, difference information between the reference position of the predetermined part and the determined position of the predetermined part, and a section that calculates, on the basis of the difference information, reliability indicating possibility that the input image is an image of the detection target.

7. A reliability acquiring method, wherein
a computer calculates, concerning an image region included in the an input image and by referring to a classifier storing section that stores information on a classifier that outputs part likelihood concerning a predetermined part of a detection target when applied to an image, the part likelihood on the basis of the information on the classifier, determines a position of the predetermined part in the input image on the basis of the calculated part likelihood, calculates, by referring to a reference position information storing section that stores information on a reference position of the predetermined part and on the basis of the information on the reference position, difference information between the reference position of the predetermined part and the determined position of the predetermined part, and calculates possibility that the input image is an image of the detection target on the basis of the difference information.

8. A program stored on a non-transitory recording medium for causing a computer to perform steps of:
-
calculating, concerning an image region included in the an input image and by referring to a classifier storing section that stores information on a classifier that outputs part likelihood concerning a predetermined part of a detection target when applied to an image, the part likelihood on the basis of the information on the classifier; determining a position of the predetermined part in the input image on the basis of the calculated part likelihood; calculating, by referring to a reference position information storing section that stores information on a reference position of the predetermined part and on the basis of the information on the reference position, difference information between the reference position of the predetermined part and the determined position of the predetermined part; and calculating a possibility that the input image is an image of the detection target on the basis of the difference information.
