This paper brings forward a new approach for region labeling by using double Pulse Coupled Neural Networks(PCNN)and morphology.Firstly,the preliminary result is got by using one PCNN and then further operation is performed on the result us-ing the other PCNN and morphology:region orientation,uniting small region,edge extraction and thinning,and region labeling.The results of computer simulations show that the method is useful and meaningful to pattern recognition.
