AUTOMATIC CLASSIFICATION OF OBJECTS WITHIN IMAGES
First Claim
1. A method in a computing device for classifying an object of a target image, the method comprising:
- providing classified images and an associated classification for each classified image, the associated classification indicating a classification of an object represented by the classified image;
identifying classified images that are most similar to the target image; and
selecting a classification for the object of the target image based on the classification of the identified classified image.

Abstract
A system for automatically classifying an object of a target image is provided. A classification system provides a collection of classified images along with a classification of the dominant object of the image. The classification system attempts to classify the object of a target image based on similarity of the target image to the classified images. To classify a target image, the classification system identifies the classified images of the collection that are most similar to the target image based on similarity between salient points of the target image and the classified images. The classification system selects a classification associated with the classified images that are most similar to the target image as a classification for the object of the target image.

11. A computer system for classifying an object of a target image, comprising:
-
a classified images store containing classified images of objects and classifications of the objects; a component that generates an index that maps feature vectors of salient points of the classified images to the classified images; a component that generates feature vectors for salient points of the target image; a component that identifies, from the generated index, classified images that match the target image based on similarity between feature vectors of salient points of the target image and the classified images; and a component that classifies the object of the target image based on the classifications of the matching classified images. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A computer-readable medium containing instructions for controlling a computing device to classify an object of a target image, by a method comprising:
-
providing an index that maps feature vectors for salient points of classified images to the classified images and their classifications; generating feature vectors for salient points of the target image; identifying, from the provided index, classified images that match the target image based on similarity between feature vectors of salient points of the target image and the classified images; and selecting a classification for the object of the target image based on the classifications of the matching classified images. - View Dependent Claims (19, 20)
