Human face location is an important basis for automatic face recognition systems. In this paper we defined one kind of symmetry transform called Directional Symmetry Transform (DST), which can provide more information about objects' shape for object recognition besides of symmetry. When applied to object detection, it can bring us much convenience. One fast algorithm based on DST was proposed for face location from frontal face image with simple background. Experimental results proved its effectiveness.
