1. A face detector training method, comprising:

  • performing a training process by;

    collecting face and non-face images as a training image sample set;

    extracting a flexible block based local binary pattern (FBLBP) feature of the face and non-face images to form an FBLBP feature set; and

    using the FBLBP feature and a GentleBoost algorithm to perform training, to obtain a first classifier, wherein the first classifier comprises several optimal second classifiers, and each optimal second classifier is obtained by training by using the GentleBoost algorithm;

    repeating the training process to obtain multiple layers of first classifiers; and

    cascading the multiple layers of first classifiers to form a face detector.
