关于传统算法指标计算问题 #5
Comments
您好,IoU的定义的确是IoU=tp/(fn+fp+tp),nIoU出现于ACM的论文中nIoU=1/n * \sum tp/(fn+fp+tp),即求IoU后求均值。 |
感谢您的答复。这里IoU=tp/(fn+fp+tp)计算完所有测试样本后,tp,fn,fp的总数吗? |

张博士您好,我在计算红外小目标检测传统算法IPI的时候遇到了问题。
我利用混淆矩阵计算指标,发现计算出来的IoU与nIoU是一样。因为IoU=tp/(fn+fp+tp),nIoU=tp/(t+p-tp)。公式表示是一样的,我感觉我算出来的是nIoU。
请问您可以教教我,如何计算红外小目标检测传统算法的IoU与nIoU吗?不胜感激。。。
