摘要: 针对最大散度差准则运用到图像分割时存在参数C不确定的问题,借助模糊概念导出参数C的初步计算公式,用二分法的迭代思想自适应地优化参数C,使最大散度差分割法获得的分割阈值相应地优化到最佳。实验证明自适应的最大散度差阈值分割法能使分割后的图像区域更均匀、细节保留得更好。

Abstract: Aiming at the uncertainty of parameter C in Maximum Scatter Difference(MSD) criterion applied in image segmentation, a preliminary formula is derived with fuzzy concept to calculate C, then optimize C adaptively based on dichotomy iterative, and the threshold obtained by MSD segmentation accordingly is optimized to a best value. Experimental results show that the Adaptive MSD(AMSD) segmentation can not only make the regions of the segmented image  more uniform, but also keep the image details better.

Key words: maximum scatter difference, image segmentation, fuzzy, adaptive
