摘要: 将微粒群算法运用于二维最大熵图像阈值分割法。首先构建图像分割的二维最大熵准则函数,然后采用适用于整数规划的微粒群算法最大化该准则函数,最终实现含噪声干扰下图像的有效分割。分割实验表明,该方法具有较强的抗噪声能力,且比普通和基于遗传算法的二维最大熵法运算速度更快。

Abstract: The PSO algorithm is used to optimize the 2-D maximum entropy for the image segmentation based on thresholds.The 2-D maximum entropy criteria function for image segmentation is built.Then,the PSO algorithm is used to maximize the criterion function.Finally,the sample images with noise are segmented effectively by the proposed algorithm.Segmentation examples show that the method proposed has greater resistance capability to noise,and is faster than the common 2-D maximum entropy approach and the 2-D maximum entropy approach based on genetic algorithm.
Key words: image segmentation, PSO algorithm, entropy, 2-D histogram
