Abstract

Biometric use physiological traits such as fingerprints, face and behavioral traits such as voice, hand signatures characteristics to verify an individual’s identity. The two process involved in biometrics are verification and identification. Verification process is performed by matching an individual’s biometric with the template of claimed identity only. The identification process performed by matching an individual’s biometric with template of every identity in the database. Existing work presented a multimodal (2D and 3D) face recognition algorithm by way of performing hybrid matching which was based on both feature and holistic metrics. The Pose of 3D face and its texture corrected using single automatically detected point and hotelling transform. 3D Spherical Face Representation (SFR) is used in conjunction with Scale-Invariant Feature Transform (SIFT) descriptor which results in formation of a rejection classifier. It quickly eliminates a large number of candidate faces at an early stage for efficient recognition for known faces as attributes. Our proposed work presented a Feature Based Multimodality Face Recognition System to recognize the human individuals in environment of known faces using features like shape of the eyes, nose and jaw. Case study and preliminary experimental results conducted in Mat lab proves to be a viable approach using multimodality method based on 2D and 3D facial representation for known faces. Facial recognition rate is measured in terms of validation index generated for false acceptance rate, false rejection rate.

Abstract

In order to provide competent and successful iris recognition, iris localization plays a major role. In this proposed method, pupil localization is done by using scaling, reverse function and four neighbours method so that irrespective of pupil‟s contour, either circle or ellipse, the pupil‟s boundary is detected accurately. For iris outer boundary detection, contrast enhancement, special wedges and thresholding techniques are used to isolate the specific iris regions without eyelid and eyelash occlusions. Upon completing the above phases, experimental result shows that, pupil and iris boundaries are detected 100% perfectly.
