Methods and systems for performing facial recognition, to train a model with reference to calculate a value of the threshold of similarity to a reference face model and to optimize an image for use in facial recognition.The invention describes a method to perform recognition of face, which method comprises the steps of generating a model of the face middle (M ~ AV ~) - comprising a matrix of states representing regions of the face from a number of different face images (I ~ 1 ~ 1 ~ 2 ~,..., I. ~ J ~) and tre Inar model face of reference (M ~ 1 ~ m ~ 2 ~,..., m ~ n ~) for each of a number of faces known, where the model of face of reference (M1, M2, m3) is based on the model of face middle (MAV). A test image (it) is acquired for a face to be identified, and a best path through the model of face middle (M ~ AV ~) is calculated, based on the test image (I ~ t ~).A degree of similarity is evaluated for each type of face of reference (M ~ 1 ~ m ~ 2 ~,..., m ~ n ~) in relation to the test image (I ~ t ~) by applying the best path of model face middle (M ~ AV ~) to each type of face of reference (M ~ 1 ~ m ~ 2 ~,..., m ~ n ~) to identify the model of the face of re Reference (M ~ 1 ~ m ~ 2 ~,..., m ~ n ~) is most similar to the test image (I ~ t ~), the model of face of reference identified (M ~ 1 ~ m ~ 2 ~,..., m ~ n ~) is subsequ00faentemente accepted or rejected based on their degree of similarity. In addition, the invention describes a system to perform recognition of face.Also, the invention describes a method and system for training a model of face of reference (M ~ 1 ~) that can be used in the face recognition system, a method and system for calculating a value of the threshold of similarity to a reference face model (M ~ n ~) that may be used in a Face recognition system, and a method and a system for optimizing images (I, R ~ t ~ I ~ t ~ g ~ 1 ~,G ~ 2 ~,..., G ~ J ~ t ~ 1 ~ t ~ 2 ~ t ~ m ~ t ~ NEW ~) that can be used in face recognition system.
