Abstract
Segmented images are prepared by dividing a large image. An intermediate target region is extracted from one segmented image selected, and an intermediate-region information item indicating the range of the intermediate target region and an intermediate feature value of the intermediate target region are acquired. This is repeated using each segmented image as the above one segmented image. Based on the acquired intermediate-region information items, an integrated feature value of a target region that integrates multiple intermediate target regions adjoining one another in the large image is obtained from intermediate feature values of the multiple intermediate target regions.
Claims7
A feature-value acquisition method of acquiring a feature value of a target region in a large image, the feature-value acquisition method comprising:
- a) preparing a plurality of segmented images obtained by dividing a large image;
- b) extracting an intermediate target region from one segmented image and acquiring an intermediate-region information item and an intermediate feature value, the intermediate-region information item indicating a range of said intermediate target region, the intermediate feature value being a feature value related to said intermediate target region;
- c) repeating said operation b), using each of said plurality of segmented images as said one segmented image;
- and
- d) based on a plurality of intermediate-region information items obtained by said operation c), acquiring a feature value of a region that integrates a plurality of intermediate target regions adjoining each other in said large image from intermediate feature values of said plurality of intermediate target regions.
A feature-value acquisition device that acquires a feature value of a target region in a large image, the feature-value acquisition device comprising:
- memory that successively stores a segmented image selected from a plurality of segmented images obtained by dividing a large image;
- a segmented-region processing unit that extracts an intermediate target region from a segmented image stored in said memory and acquires an intermediate-region information item and an intermediate feature value, the intermediate-region information item indicating a range of said intermediate target region, the intermediate feature value being a feature value of said intermediate target region;
- and
- an integration processing unit that, based on a plurality of intermediate-region information items, acquires a feature value of a region that integrates a plurality of intermediate target regions adjoining each other in said large image from intermediate feature values of said plurality of intermediate target regions.
