Scene Classification Apparatus and Scene Classification Method
First Claim
1. A scene classification apparatus, comprising:
- a characteristic amount obtaining section that obtains a partial characteristic amount indicating a characteristic of a partial image that is a portion of a classification-target image;
a partial classification section that classifies, based on the partial characteristic amount obtained by the characteristic amount obtaining section, whether or not the partial image belongs to a predetermined scene;
a detection section that detects the number of the partial images classified by the partial classification section as belonging to the predetermined scene; and
a decision section that decides, according to the number of the partial images detected by the detection section, whether or not the classification-target image belongs to the predetermined scene.

Abstract
A scene classification apparatus includes: a characteristic amount obtaining section that obtains a partial characteristic amount indicating a characteristic of a partial image that is a portion of a classification-target image; a partial classification section that classifies, based on the partial characteristic amount, whether or not the partial image belongs to a predetermined scene; a detection section that detects the number of the partial images classified as belonging to the predetermined scene; and a decision section that decides, according to the number of the partial images detected by the detection section, whether or not the classification-target image belongs to the predetermined scene.

10. A scene classification method, comprising:
-
obtaining a partial characteristic amount that indicates a characteristic of a partial image that is a portion of a classification-target image; classifying, based on the obtained partial characteristic amount, whether or not the partial image belongs to a predetermined scene; detecting the number of the partial images classified as belonging to the predetermined scene; and judging, according to the number of the detected partial images, whether or not the classification-target image belongs to the predetermined scene.

11. A scene classification apparatus, comprising:
-
a storage section that stores at least either one of presence probability information indicating, for each of partial regions, a presence probability that a characteristics of the predetermined scene appear, and presence-probability ranking information indicating an order of the presence probability for a plurality of the partial regions, the partial regions being obtained by dividing an entire region of an image belonging to a predetermined scene; a characteristic amount obtaining section that obtains a partial characteristic amount indicating a characteristic of a partial image that is a portion of a classification-target image and that corresponds to the partial region; a partial evaluation section that evaluates, based on the partial characteristic amount obtained by the characteristic amount obtaining section, whether or not the partial image belongs to the predetermined scene, in a descending order by the presence probability based on at least either one of the presence probability information and the presence-probability ranking information that are read out from the storage section; and a decision section that decides, according to an evaluation value obtained by the partial evaluation section, whether or not the classification-target image belongs to the predetermined scene. - View Dependent Claims (12, 13, 14, 15, 16, 17)
