在图像精度评价中，主要用于比较分类结果和实际测得值，可以把分类结果的精度显示在一个混淆矩阵里面。混淆矩阵是通过将每个实测像元的位置和分类与分类图像中的相应位置和分类像比较计算的。-In the image to　uate the accuracy, mainly for comparison of classification results and the actual measured value, the accuracy of the classification results are displayed in a confusion matrix inside. The confusion matrix is measured by each pixel position and image classification and classification in the appropriate location and classified as comparative calculations.
