METHOD AND APPARATUS FOR LOCALIZING AN OBJECT WITHIN AN IMAGE
First Claim
1. A computer implemented method for localizing objects within an image, comprising:
- accessing at least one object model representing visual word distributions of at least one training object within training images;
detecting whether an image comprises at least one object based on the at least one object model;
identifying at least one region of the image that corresponds with the at least one detected object and is associated with a minimal dissimilarity between the visual word distribution of the at least one detected object and a visual word distribution of the at least one region; and
coupling the at least one region with indicia of location of the at least one detected object.

Abstract
An improved method and apparatus for localizing objects within an image is disclosed. In one embodiment, the method comprises accessing at least one object model representing visual word distributions of at least one training object within training images, detecting whether an image comprises at least one object based on the at least one object model, identifying at least one region of the image that corresponds with the at least one detected object and is associated with a minimal dissimilarity between the visual word distribution of the at least one detected object and a visual word distribution of the at least one region and coupling the at least one region with indicia of location of the at least one detected object.

9. A computer implemented method of localizing objects within an image, comprising:
-
extracting visual words from an image to determine a visual word distribution; segmenting the image into a plurality of regions, wherein each of the plurality of regions comprises at least one of the extracted visual words; minimizing a dissimilarity between at least one object model for defining at least one object and at least one visual word distribution for at least one region of the plurality of regions, wherein the at least one region forms the at least one object; coupling the at least one region with indicia of location as to the at least one object. - View Dependent Claims (10, 11, 12)
