Automated image segmentation based on pulse coupled neural network with partide swarm optimization and comprehensive evaluation
Multi-parameter setting and single segmentation evaluation criterion are the problems in image segmentation based on Pulse Coupled Neural Network (PCNN). Through combining Particle Swarm Optimization (PSO) with comprehensive evaluation criterion
this paper presented an automatic image segmentation algorithm based on PCNN. The improved PCNN model with monotonically increasing threshold search strategy was utilized in this algorithm. The Comprehensive Evaluation Criterion(CEC) obtained by cross-entropy parameter
edge matching degree and noise control degree were proposed as the fitness of particles in PSO
then the parameters of PCNN such as the target time constant
the connection coefficient and the iteration times n were acquired adaptively by updating fitness value of particles. By using these acquired optimum parameters
the image was segmented by the improved PCNN. For different types of images
experimental results show that algorithm proposed can segment image completely and accurately under PCNN operating efficiency
moreover texture details are retained. Compared with other experimental methods
the segmented results obtained by proposed algorithm are superior to that obtained by other algorithms in CEC 10.5%. In addition
the general comprehensive indicators of the segmented results obtained in this research are also optimal. Thus
it can be seen that the objective evaluations are consistent with the visual subjective evaluations
and the algorithm proposed has high robustness.
