English Abstract

There are a wide variety of mechajiisms available for performing the authentication function.

One of them is by using video film to monitor important places.

In such systems the important task is recognizing human faces which needs good segmentation and high feature extraction.

In traditional technique the segmentation can be performed by region growing and shrinking, clustering method, and boundary detection which all take image pixels, pixel by pixel and compare each with neighbors to get the similarity while chaotic oscillator depends on synchronization concept between points to determine the active points which is construct similar region which determine the object This object may not be human face so development (RGB, IISV, YCbCr) color space is by combining them due to skin color.

Skin color model aids the process of separating the face from the scene due to its skin color.

After isolating the human face image which is contains many features (eye, eyebrow, nose, etc..) they identity the person, chaotic oscillator is used to extract the important features by removing any point that is not synchronized with its neighbors and gives new image which contains only the main face features and then compares this image with stored image in DB of authorized person and make decision on if (he / she) an authenticated person or not.
