METHOD AND APPARATUS OF RECOGNIZING PATTERNS USING MAXIMIZATION OF MUTUAL INFORMATION BASED CODE SELECTION FOR LOCAL BINARY PATTERNS, AND RECODING MEDIUM THEREOF

摘要

PURPOSE: A pattern recognizing method, apparatus thereof, and recording medium thereof which uses local LBP are provided to increase recognition performance and ratio by expressing an image through a few codes between classes. CONSTITUTION: A learning face image converts a training face image into an LBP(Local Binary Pattern) and generates a feature vector based on a class label vector(101). A frequency feature vector is calculated by showing the frequency of LBP codes of the learning face image. An OLBP(Optimal Local Binary Pattern) code for maximizing the class label vector is selected. The face image is registered by a template feature vector.
