FACE RECOGNITION TECHNIQUES
[attachment=27512]
INTRODUCTION
"The old days were better when the instructor use to call out the names and take the attendance. Now the proxy attendance has become a dream by the advent of this new automated system"
Well, the day is not far when the students will be talking likewise while coming out of the lecture halls. Here, we present one such attempt towards making this dream come true.
Positive identification of individuals is a very basic societal requirement. In small tribes and villages, everyone knew and recognized everyone else. You could easily detect a stranger or identify a potential breach of security. In today’s larger, more complex society, it isn’t that simple. In fact, as more interactions take place electronically, it becomes even more important to have an electronic verification of a person’s identity. Until recently, electronic verification took one of two forms. It was based on something the person had in their possession, like a magnetic swipe card, or something they knew, like a password. The problem is, these forms of electronic identification aren’t very secure, because they can be given away, taken away, or lost and motivated people have found ways to forge or circumvent these credentials. The ultimate form of electronic verification of a person’s identity is biometrics; using a physical attribute of the person to make a positive identification.
FUNCTIONAL REQUIREMENTS :-
After getting valuable information we reached to the following important conclusions: -
1. It should meet the functional requirements as mentioned in Objectives.
2. It should be able to handle 'gif' and 'jpeg' imges.
NON FUNCTIONAL REQUIREMENTS :-
This project is intended to meet the following non functional requirements: -
1) This face recognition software should be available on the Internet, to enable the users to use , download it any time.
2) The program should be platform independent.system therefore it is expected that the database would perform functionally the entire requirement that are specified by the user.
IMPLEMENTATION
IMPLEMENTATION REQUIREMENTS:-
This project is intended to be web based, portable and platform independent. Not only this, having an interactive and user friendly GUI is order of the day in this graphical world in which case deciding a proper language is very crucial. Java is found to be appropriate to implement this project. Java has many features, which have made this project possible by putting reasonable efforts. Details of all the tools used in this project are given in the next section.
PHOTO PROCESSING
The new face recognition algorithm performs a very computationally-demanding set of operations over the photo in order to detect all the faces present in the image.
The two main sources of information for this detection are:
The result of the correlation between the photo and each of the template faces that are provided to the algorithm.
The colour of the skin in the photo, which is compared to the average colour of the template faces provided to the algorithm.
