Abstract: A number of algorithms have been developed for face recognition including ACO (Ant Colony Optimization) which is really a efficient optimization algorithm for finding the best option from a number of available ones. Face Recognition includes feature extraction; feature selection; identification of image.Feature selection in research area evolved a no. of methods eg.PCA; LDA; DCT etc. And selection also have no. of evolved methods likewise ABC; ACO; GA etc. This paper presents an review and detail analysis of a new approach using mathematical filter (mixed) approach for feature extraction; and simple Fetaure selection using combined equation for optimization.Finally; identification is done by Ant Colony Optimization.The analysis reports a good results in recognition efficiency and time cost factor reduction.It will be useful for new researchers exploring its use in their research problems.
