Abstract: This paper presents an algorithm of face recognition based on a LBP（Local Binary Pattern） operator and Isomap.It uses an [ε]-LBP operator to extract texture features of face images，and utilizes Isomap which is a non-linear data dimensionality reduction method to reduce the data dimensionality，the nature of available data structures is extracted.Let the nature data structures as inputting for the classifier of the face classification.The experimental results show that this algorithm is able to face a good image classification and recognition，especially in the case of small samples.
