Why we choose face recognition

over other biometric

It requires no physical interaction on behalf of the user.

It is accurate and allows for high enrolment and verification rates.

It does not require an expert to interpret the comparison result.

It can use our existing hardware infrastructure, existing cameras and

image capture Devices will work with no problems

It is the only biometric that allow us to perform passive identificationin a one to many environments (e.g.: identifying a terrorist in a busy

Airport terminal)

Applications

Advantages & Limitation

Advantages:

Its convenience and Social acceptability. all we need is our picture taken for it to

work.

Face recognition is easy to use and in many cases it can be performed without a

Person even knowing.

Face recognition is also one of the most inexpensive biometric in the market and Its

price should continue to go down.

Limitation:

Face recognition systems can’t tell the difference between identical twins.

Face Detection

Algorithm used:

viola-jones algorithm (CascadeObjectDetector)

Working parameters:

detect FrontalFaceCART, LeftEye, RightEye, Mouth, and Nose simultaneously

Toolbox

Image Processing Toolbox

Computer Vision System Toolbox

Main functions:

detectFaceParts: Detects frontal faces with parts.

detectRotFaceParts: Detects faces with parts rotating an input image

Advantage:

The performance is improved compared to the default usage of the face detection

Our Future work

After detection part we will match the detected image with a test

image.

We are also working to create a database for our input images.

Then we do the Recognition Part
