Automatic and Semi-automatic Image Classification, Annotation and Tagging Through the Use of Image Acquisition Parameters and Metadata
First Claim
1. A method of semantically characterizing the semantic attributes and contents of digital or non-digital images by analyzing image acquisition metadata, data affiliated with the image, and/or the image itself, the image, image acquisition metadata and data affiliated with the image being stored on a non-transitory computer-readable storage medium, and using probabilistic or deterministic relationships among the metadata and/or affiliated data to create a semantic image characterization which is used to enrich pre-existing metadata and/or affiliated data or is used to index the image contents in a computer readable storage medium in order to facilitate future retrieval of the image using semantic terms via a data processing apparatus.

Abstract
A method for characterizing image contents automatically or semi-automatically using image acquisition parameters and metadata is presented. The method establishes probabilistic and deterministic relationships between different types of metadata and the semantic attributes and contents of images. It furnishes a mechanism that enables the automatic and semi-automatic classification, annotation, tagging, indexing, searching, identification or retrieval of images based on their contents, semantic properties and metadata characteristics. The method uses, but is not limited to, image capture metadata such as focal length, exposure time, relative aperture, flash information, ISO setting, angle of view, subject distance, timestamp, GPS information as well as other forms of metadata, including but not limited to, captions, keywords, headings, tags, comments, remarks, titles which may be automatically, semi-automatically, or manually generated. The present invention can be applied to image databases, web searching, personal search, community search, broad-based or vertical search engines for internet, intranet, extranet or other usages.
