以CE-shape数据库为例来计算弦长关联算法相似性测度。-With CE-shape database as an example to calculate the chord length correlation algorithm similarity measure.

Hist13.m获得的图像区域弦长关联特征，该算法原理可通过搜索chord context关键词获得。-Hist13.m acquired image region associated with chord length feature of the algorithm, this paper can be obtained by searching for keywords chord context.

本文根据椭圆弦长的比值相对固定提出了弦长比法, 并运用SOM 神经网络对纽荷尔脐橙进行分级, 取得了一定的效果。-Based on the ratio of elliptical chord chord made relatively fixed ratio method, and the use of SOM neural network for classification of Newhall navel orange, and achieved some results.

采用的是基于弦中点的hough变换椭圆检测算法，大家可以在百度上搜这篇论文，由于不是用的标准hough变换的算法，所以运行速度还不错-Used is based on the midpoint of the chord hough transform ellipse detection algorithm, we can search on Baidu paper, because the algorithm is not used in standard hough transform, so
