Research on Improved PSO Algorithm Based on Contour Detection

In this paper, an improved PSO algorithm in unimodal, multimodal function can adapt quickly converges to a smaller fitness value. It’s suitable for complex non-linear environment. Combined with the adjusted Snake model can better convergence at the edge of the recess. Compared with other contour detection algorithms, this algorithm has better noise robustness, contour convergence accurate and efficient accuracy and efficiency.
