Abstract: The key problem of face detecting based on feature.is extracting features.In this paper,a method of feature model based face detecting is proposed.It extracts features from eyes and nose,and then constructs a triangular feature mold component with eyes and nose.The search is taken in the candidate feature image by changing the size of blocks step by step.This processing can obtain separate points of feature mold.And finally proposes a strategy based on the knowledge about facial structure/distribution to search the feature mold.Experimental results prove that this method can rapidly and accurately detect face in an image with complex background.Furthermore,it can perform well for multiple faces.
