OPTIMIZED PCA BASED FACE RECOGNITION
In this paper an algorithm to solve the problem of automatic face recognition is presented. The novelty of the algorithm is the ability to combine the principal component analysis (PCA) with Modified Particle Swarm Optimization (MPSO) to improve the execution time and to obtain better face recognition results. The efficiency of face recognition system is imp measure the similarity of an input face compared with a database of faces. The use of the fitness function helps to obtain more accurate results in a faster way. The results obtained are excellent even when the system w A comparison of the results obtained with the algorithm without MPSO versus the algorithm using MPSO is also presented. The algorithm is also implemented on the colored images of the human faces. Keywords: Particle Swarm Optimization, Face Recognition, Eigenfaces, Evolutionary Computer Vision.
