Video-based Automatic System for Iris Recognition (VASIR) is a NIST implemented iris recognition algorithm designed to work on both conventional iris images and iris images collected at a distance.
VASIR is fully automated system of the video-based iris recognition for less-constrained videos. All videos were captured while a person walked through a portal at a distance. The system was developed to address the challenge of recognizing a person in less-than-optimal environments, coping with high and low still-image and video-sequence quality.
As shown in figure above, VASIR can be principally categorized into seven parts of components:
VASIR has the capacity to automatically detect the eye region and subsequently to automatically select the best quality iris image from video. After the process, VASIR carries out a comprehensive comparison analysis of biometric samples which in turn yields a state-of-the-art individual verification.
VASIR also accommodates multiple scenarios:
In VvsV matching, the extracted iris region of distant-video-sequences is matched to other sequences from the same video sequence or from a different video sequence of the same person. VvsS means that the video-sequence captured at a distance is compared to classical-still-images, captured by a different camera. In SvsS matching, a classical-still-image is matched against other classical-still-images of the same person that were captured by the same device.
VASIR's performance and practical feasibility have been evaluated using the Multiple Biometric Grand Challenge (MBGC) dataset.
Currently, the VASIR source code beta version 1.0 and its user guide are available. This source code is not the completed version. Note that you may get a known warning or memory related messages.
We plan to update each component of VASIR incrementally, after evaluating its performance.
Type of software: Open source research software for automated iris recognition.
