| 摘 要： | 通过分析交叉熵阈值法的计算时间量较大的问题,提出了基于卡方散度的图像阈值化分割新准则,并从理论上分析了它与交叉熵阈值法的计算复杂性.实验结果表明,提出的图像分割准则是可行的,且计算所需时间比交叉熵阚值法有了明显减少,它对一定强度噪声干扰的图像比交叉熵法能获得更好的分割结果.

| Abstract: | By means of analyzing existing problem of cross entropy thresholding method with much computation time,the new image thresholding segmentation criteria based on Chi-square divergence is proposed in this paper.Theoretical computation complexity of thresholding segmentation methods based on Chi-square divergence and cross entropy is analyzed.Experimental results show that Chi-square divergence based image thresholding method is feasible,and its computation time is much less than that of cross entropy threshol... |
