This document presents a proposed approach for biometric authentication using facial vein patterns captured in thermal images. The system aims to address limitations of existing identification systems. It involves extracting thermal signatures from registered infrared face images using morphological operators and directional/diffusional filters. Signatures are matched against templates for authentication. The proposed approach is intended to provide a more secure and accurate identification system compared to alternatives that are sensitive to factors like lighting. It involves modules for image registration, face segmentation, signature extraction, and feature matching between extracted signatures and stored templates. Results show an average accuracy of 87.16-94.63% for the matching algorithm.

2. OBJECTIVE
• This project is concerned with the task of identifying the
individual’s thermal facial signature for the purpose of
authentication.
• It includes image acquisition, coding the matching algorithm
for processing the face vein pattern and testing of algorithm
module. It can also be used to decrease the percentage of false
rate and rejection rate identification of a person.

3. ABSTRACT
A new approach towards biometric authentication system using
face vein is to identify the problem of human face recognition. Different
approaches to the problems of face detection and face recognition were
evaluated and implemented using the Matlab technical computing language.
In the implemented frontal-view face detection systems, automated face
detection was achieved based on image invariants. The proposed algorithm
is fully integrated and consolidates the critical steps of feature extraction
through the use of morphological operators, registration using the Linear
Image Registration Tool, and matching through unique similarity measures
designed for this task. The novel approach at developing a thermal signature
template using four images taken at various instants of time ensured that
unforeseen changes in the vasculature over time did not affect the biometric
matching processes the authentication process relied only on consistent
thermal features. The results are based on applying the directional filter
with anisotropic diffusion filter and achieved an average accuracy of
87.16% for skeletonized signatures and 94.63% for anisotropically diffused
signatures with directional filters. The highly accurate results obtained in
the matching process clearly demonstrate the ability of the thermal infrared
system to extend in application to other thermal-imaging-based systems.

4. EXISTING SYSTEM
Identification systems rely on 3 key elements
1. Attribute identifiers
2. Biographical identifiers
3. Biometric identifiers
DISADVANTAGES:
• It is easy to forge by intruders.
• Less secure
• Sensitive to light variability and other factors like difficulty in
detecting facial disguises.

5. PROPOSED SYSTEM
• We are implementing an biometric authentication system
which uses facial signature to recognize an person’s identity.
• In this the thermal image are taken and features are extracted.
• The extracted features are enhanced by combining diffused
and directional filters.
ADVANTAGES:
With the combined use of Directional and Diffusional
filter, the images extracted are clear and efficient.

8. DESIGN OF PROPOSED WORK
• Module-I:Thermal infrared-Image Registration& Face
Segmentation
• Module-II :Thermal Signature Extraction
• Module-III : Feature Matching

9. MODULES
MODULE-I:
Thermal infrared-Image Registration& Face Segmentation
• Data is collected using mobile camera system which
operates in thermal vision.
• The frontal view of the image is registered.
• Using the dual-front contour region growing technique
the face image are segmented from the neck and hair
region.

10. MODULE-II
Thermal Signature Extraction
• Noise Removal:
The significance of the anisotropic diffusion filter is to
reduce spurious and speckle noise effects seen in the
images.
• Image Morphology:
The top-hat segmentation is used to enhance the
brightness of the object in the image.
• Post Processing:
The skeletonization process is used o reduce the
foreground regions into a skeletal remnant that largely
preserves the extent and connectivity of the original region.

11. MODULE-III:
Feature Matching:
• The thermal signature which is extracted is matched with
the N number of templates stored in the database
• If both the template and the signature is matched, the
individual is authorized else they are unauthorized person

31. ADVANTAGES
• Passport and visa verification can also be done using face
Recognition technology as explained above. Even Driving
license verification can also be exercised face recognition
technology as mentioned earlier.
• To identify and verify terrorists at airports, railway stations
and malls the face recognition technology will be the best
choice in India as compared with other biometric technologies
since other technologies cannot be helpful in crowd places.

32. FUTURE ENHANCEMENT
• Next generation person recognition systems will need to
recognize people in real-time and in much less constrained
situations.
• We believe that identification systems that are robust in natural
environments, in the presence of noise and illumination
changes, cannot rely on a single modality
