摘 要: 针对分割图像目标是无法提取目标的真实边缘且实时性不佳,引入混沌系统改进的PSO(简化粒子群算法)提取出的目标边缘作为Snake模型分割的起始位置,优化能量函数后分割出精准目标.实验表明:对图像目标进行分割的时间减少且精准度也提高了。 Aiming at the difficulty to segment the real edge and slow convergence, we introduced chaos system into PSO( sim- plified particle swarm algorithm) to get the contour as initial position of Snake Model' s energy function, then get a precise target. Experiments show that the segmentation target time and efficiency are improved significantly.
