《MATLAB神经网络30个案例分析》中的第17个例子，案例17 SOM神经网络的数据分类--柴油机故障诊断。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 17 cases of 17 SOM neural network data classification, diesel engine fault diagnosis. Hope to have certain help to everybody! )

归一化切割和图像分割算法及其论文,归一化分割不仅度量了不同分组之间总体不相似性，同时度量了分组内的总体相似性(Normalized cuts and image segmentation algorithm and its papers, normalized measure divided not only between the different groups no overall similarity, while the overall measure of similarity within groups)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.
