Automatic and Semi-automatic Image Classification, Annotation and Tagging Through the Use of Image Acquisition Parameters and Metadata

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