提出了一种新的基于凹点和椭圆拟合的接触单元分割算法。该算法包括轮廓预处理和椭圆处理两部分。轮廓预处理的目的是平滑轮廓的起伏，找出轮廓的凹点，通过凹点将轮廓分割成不同的线段。椭圆处理的目的是通过使用拟合的椭圆的属性将轮廓的不同部分处理成可能的单个单元。由于凹点将接触细胞的整个轮廓分成不同的段，并且单个细胞的不同部分具有相似的性质，椭圆处理可以通过椭圆拟合来分离接触细胞。提出了一种用椭圆拟合法分割接触单元格二值轮廓的新方法。实验结果表明，该算法是有效的。(C)2009爱思唯尔有限公司。保留所有权利。
A new touching cells splitting algorithm based on concave points and ellipse fitting is proposed in this paper. The algorithm includes two parts: contour pre-processing and ellipse processing. The purpose of contour pre-processing is to smooth fluctuations of the contour, find concave points of the contour and divide the contour into different segments via the concave points. The purpose of ellipse processing is to process the different segments of the contour into possible single cells by using the properties of the fitted ellipses. Because concave points divide the whole contour of touching cells into different segments and different segments of one single cell have similar properties, the ellipse processing can separate the touching cells through ellipse fitting. This paper demonstrates a new way of using ellipse fitting to split the binary contour of touching cells. Experimental results show that our algorithm is efficient. (C) 2009 Elsevier Ltd.
