'ABSTRACT Automatic recognition of people has received much attention during the recent years due to its many applications in different fields such as law enforcement, security applications or video indexing. Face recognition is an important and very challenging technique to automatically recognize people's face. Face recognition systems play a vital role in many applications including surveillance, biometrics and security as the rapid development of computer science and pattern recognition, visual technology is widely applied in industry and daily life. The goal of this research is to implement face recognition on a real life platform for security system. The software should be able to take an image of a person through the camera connected to the USB of a computer, recognize the individual based on previously stored samples and grant access or deny access through a device connected to another port of the same computer. The method that will be considered is principal component analysis (PCA) method for face recognition. A database of trained images is stored on the computer for recognizing a test image. The image from the camera is resized and cropped with MATLAB. This image is further processed by comparing it with images in the database. If it matches any of the images in the database, a signal is sent to a device connected to another USB port (Embedded system) to grant access for the person that the image is taken from. If the image does not match any of the images in the database then, the accessis denied for the person. Key words: Face recognition, PCA, Embedded system'
