| Abstract: | A new multidimensional pulse coupled neural network model was proposed, which integrated with the vector gradient to implement color image edge detection. To test the feasibility and effectiveness of multidimensional PCNN on edge detection of microscopic color cell images, the experiments of the microscopic cell images were carried out. Empirical results show that multi-dimensional PCNN outperforms classical methods in terms of noise resistence and accuracy of weak edge detection. |
