Abstract: This lecture is a survey on biometrics and forensics, especially methods of image processing and recognition for human identification. A biometric system is a pattern recognition system that recognizes a person on the basis of a feature vector derived from a specific physiological or behavioral characteristic that the person possesses.
All biometric systems work in a similar fashion:
- The user submits a sample that is an identifiable, unprocessed image or recording of the physiological or behavioral biometric via an acquisition device.
- This image and/or biometric is processed to extract information about distinctive features.
Biometric systems have four main components: sensor, feature extraction, biometric database, matching-score and decision-making modules.
The processes of forensic computing can be divided into three main areas:
- Image Capture - The Imaging process is fundamental to any computer investigation.
- Image Processing - The processing software to extract features of the target image.
- Investigation.
Distinctions between biometrics and forensic are based on the fact that biometrics methods are implemented on live subjects. Techniques designed for person identification in biometrics can be utilized for forensic purposes.
Personal attributes used in a biometric identification system can be physiological, such as facial features, fingerprints, iris, retinal scans, hand and finger geometry; or behavioral, the traits idiosyncratic of the individual, such as voice print, gait, signature, and keystroking.
In this paper a recognition methods are presented for recognizing a person on the basis of a feature vector derived from a biometrics templates/images.
