- Most systems are intelligent and the industrial world is moving now towards technology. Most industrial systems are now computerized and offer a high speed. However, Face recognition is a biometric system that can identify people from their faces. For few number of people to be identified, it can be considered as a fast system. When the number of people grew to be bigger, the system cannot be adopted in a real-time application because its speed will degrade along with its accuracy. However, the accuracy can be enhanced using pre-processing techniques but the time delay is still a challenge. A series of experiments had been done on AT&T-ORL database images using Enhanced Face Recognition System (EFRS) that is adopting a Local Binary Pattern Histogram (LBPH) as feature extraction method. During these experiments, LBP parameters and pre-processing techniques have been changing and the results were recorded for accuracy and time for different database sizes. The accuracy reaches 98.5% but the time delay keep increasing with the number of people in the database.
