Automatic face alignment system for robust face recognition and method therefor

PURPOSE: An automatic face aligning system is provided to automatically align face images obtained in a daily life. CONSTITUTION: A feature point extracting unit(20) extracts the feature point of an input face image and a reference face image. A feature point distribution operation unit(30) operates the distribution of the feature point. An entropy processing unit(40) produces the entropy value. An image transforming unit(50) transforms the input face image. A face detection unit(60) detects the final face from the input face image through the comparison result of the entropy processing unit.
