摘要: 针对如何自适应选取二维Renyi熵阈值分割法中参数α的问题,基于一种图像分割质量评价指标——均匀性测度,利用粒子群优化搜索方法,提出了一种自适应选取参数α的方法。实验表明,所提出的方法可以有效地选取参数α,获得理想的图像分割结果。

Abstract: To select the parameter α in two-dimension Renyi entropy image thresholding segmentation method adaptively,a new preferences method is proposed.The presented method is based on uniformity measure,an image segmentation valuation criteria,and particle swarm optimization algorithm.The experiment results show that the novel method can get the suitable parameter α and idea segmentation results.
