Face Biometric Data Indexing

Face-based biometric identification system with a large pool of data requires huge computation time to search an individual’s identity from database due to the high dimensionality of the face biometric features. In this work, a new indexing technique is proposed for face-based biometric identification system to narrow down the search space. The technique is based on the Speed Up Robust Feature (SURF) key points and descriptors [10]. Index keys are generated for a face image from the key points and descriptors of the face image. A two level index space is created based on the extracted key points. A storing and retrieving techniques have been proposed to store and retrieve the face data to or from the proposed ...
