Face recognition accuracy is easily affected by the tilted face or reflective and shadow from eyeglasses on facial features. In this thesis, an integrated affine transformation and eyeglasses reduction method have been proposed, where affine transformation method makes tilted face into normal one and eyeglasses reduction method is realized by eyeglasses symmetrical features and image morphology operations. In recognition stage, sobel edge detection algorithm is first adopted to calculate the edge of the face image, and then figure out orthogonal projection coefficient of facial feature and its similarity measure by using Euclidean distance.

Face image normalization by affine transformation and eyeglasses reduction is effective in improving the error of face recognition that caused by the tilted face or worn eyeglasses.
