Image processing apparatus, method, and program
First Claim
1. An image processing apparatus, comprising:
- extraction means configured to extract a characteristic amount of a region in which a recognition object may possibly be included from within an image of a processing object;
parameter retaining means configured to retain a parameter regarding the recognition object;
context retaining means configured to retain a context regarding the recognition object; and
decision means configured to decide based on the characteristic amount extracted by said extraction means, the parameter retained in said parameter retaining means, and a result of arithmetic operation performed using the context retained in said context retaining means whether or not an image in the region is the recognition object,wherein said decision means decides whether or not there exists a region in which a score calculated using the characteristic amount and the parameter is higher than a predetermined threshold value, andperforms, where it is decided that a region in which the score is higher than the predetermined threshold value exists, arithmetic operation regarding the recognition object corresponding to an image other than an image in the region using the characteristic amount, the parameter, and the context.

Abstract
An image processing apparatus includes an extraction section, a parameter retaining section, a context retaining section, and a decision section. The extraction section extracts a characteristic amount of a region in which a recognition object may possibly be included from within an image of a processing object. The parameter retaining section retains a parameter regarding the recognition object. The context retaining section retains a context regarding the recognition object. The decision section decides based on the characteristic amount extracted by the extraction section, the parameter retained in the parameter retaining section, and a result of arithmetic operation performed using the context retained in the context retaining section whether or not an image in the region is the recognition object.

7. An image processing method, comprising the steps of:
-
extracting a characteristic amount of a region in which a recognition object may possibly be included from within an image of a processing object, utilizing an extraction section; retaining a parameter regarding the recognition object, utilizing a parameter retaining section; retaining a context regarding the recognition object, utilizing a context retaining section; and deciding based on the characteristic amount extracted by the process at the extraction step, the parameter retained by the process at the parameter retaining step, and a result of arithmetic operation performed using the context retained by the process at the context retaining step whether or not an image in the region is the recognition object, utilizing a decision section, wherein the deciding step decides whether or not there exists a region in which a score calculated using the characteristic amount and the parameter is higher than a predetermined threshold value, and performs, where it is decided that a region in which the score is higher than the predetermined threshold value exists, arithmetic operation regarding the recognition object corresponding to image other than an image in the region using the characteristic amount, the parameter, and the context.
