SURVEY ON MULTISPECTRAL BIOMETRIC IMAGES

Abstract

Electromagnetic theory says that hertzian waves provide stronger penetrability into objects. Multispectrum illuminator can penetrate tissues at different depths and form images of both surface skin textures and hypodemia. This multi-spectrum sensor provides greater acquisition time and better quality images than any other unimodal sensors. There are many biometric features available like hand, finger, iris, palm etc which are used for various authentication and identification purposes. These features can be captured using various technologies like optical, ultra sound, multispectral and many more. Among all multispectral images have proven for efficient results in both recognition and identification systems. In this paper we will make a study of various multispectral biometric modalities and their acquisition techniques.
