A fast mouth detection algorithm based on face organs

Automatic mouth detection in a complex background is one of the most challenging and significant tasks in the field of computer vision and pattern recognition. A new mouth detection method that uses the relationships of face organs based on the award-winning mosaic method. The new method redesigns the policy of face blocks. Experimental results show that the algorithm can finds out the mouth region rapidly. It is also useful in a wide range. Moreover, it is effectual for complex background such as public mouth detection.
