遥感数字图像计算机分类，监督分类，kappa系数的实现

输入特征向量训练随机森林分类模型，并计算分类结果的Kappa系数，混淆矩阵，准确性，特异性和敏感性。

本代码可计算kappa相关系数。 % KAPPA: This function computes the Cohen's kappa coefficient. % Cohen's kappa coefficient is a statistical measure of inter-rater % reliability. It is generally thought to be a more robust measure than % simple percent agreement calculation since k takes into account the % agreement occurring by chance.

基于MATLAB的KAPPA系数计算。The confusion matrix was used to describe the classification accuracy and to characterize the errors. Landis and Koch (1977) classified Kappa values into different categories: 0-0.20, 0.21-0.40, 0.41-0.60, 0.61-0.80 and 0.81-1, which indicates slight, fair, moderate, substantial and almost perfect agreements, respectively.
