Statistical Approach to Large-scale Image Annotation
First Claim
Patent Images
1. A method of annotating an image comprising:
- compiling visual features and textual information from a plurality of images;
hashing the plurality of visual features, and clustering the plurality of images based on the hash value;
building one or more statistical language models based on the clustered images; and
annotating the image using one or more of the statistical language models.

Abstract
Statistical approaches to large-scale image annotation are described. Generally, the annotation technique includes compiling visual features and textual information from a number of images, hashing the images visual features, and clustering the images based on their hash values. An example system builds statistical language models from the clustered images and annotates the image by applying one of the statistical language models.

12. A computer readable storage medium comprising computer executable instructions that when executed by a processor perform a method comprising:
-
crawling a large-scale image database to gather a plurality of images; compiling visual features and textual information from the plurality of images; extracting visual information from the plurality of images by using a gray block methodology; reducing the visual information by employing a projection matrix; hashing the reduced visual information, and clustering the plurality of images based on a hash value; building one or more statistical language models based on the clustered images; and annotating a query image using one or more of the statistical language models. - View Dependent Claims (13, 14, 15, 16, 17, 18)
