Abstract:Fast radial symmetry transform can fast detect points of interest and is the improvement of generalized symmetry transform.Firsly,the location of eyebrows is estimated.According to the location of eyebrows,in certain range that possibly includes eyes,fast radial symmetry transform is used to detect black points of interest.After rectifying a deviation and according to the geometrical features,the eyes candidates are selected and the precise location can be decided by pupil model.The experiments in ORL and SJTU-IPPR fact database show the algorithm is effective and can be used in real-time system.
