Biometrics Database

QS Biometrics Database
Laboratory grade face and speech data for testing and validation

The Quantum Signal Biometrics Database (QSBD) contains an extensive, high quality set of still images, video recordings, and audio recordings of more than 300 human subjects. The data was collected during a 1.5 year, 40,000 man-hour experiment conducted from 2003 to 2004 in the university town of Ann Arbor, Michigan. The collection experiment was designed and executed by a highly experienced team of data acquisition experts and signal/image processors with the intent of providing a high-quality corpus from which to develop and text speech, face, or multimodal biometrics algorithms and/or software.
