Content based Image Indexing & Retrieval

Multimedia (Images) are being generated at an enormous rate by sources such as defense and civilian satellites, biomedical imaging, military reconnaissance and surveillance flights and home entertainment systems, scientific experiments, fingerprinting and mug-shot-capturing devices. For example, National Aeronautics and Space Administration (NASA) Earth Observing System will produce about 1 TB of image data per day when completely operational. A content- based image retrieval (CBIR) system is required to efficiently and competently use information from these image data sets. Such a system that helps users who is unfamiliar with the database can retrieve relevant images based on their contents.
