Average Recall(AR)这个评价指标使用的不多,虽然COCO的12个评价指标里面有6个是Average Precison(AP),六个是AR,但是因为COCO在说明评价指标的时候说了主要以各种AP为主要评价指标,因此AR其实用的人不多了,近些年的文章也一般都是用6个AP指标。 AR这个指标最早是从文章What Makes for Effective Detection Proposals?

Average Precision (AP)的精确定义是Area Under Precision-Recall Curve AP = \int_{0}^{1}\text{PR}(r)\text{d}r \\ Precision-Recall Curve 注意,在实际工程当中,没有真实的连续曲线,需要指定离散的recall 比如COCO采用的就是[0:.01:1],101个 recall 作为阈值,并按照下列公式近似 \text{AP} = \fra...
在COCO数据集中,更关注预测框位置的准确性,AP值是针对多个IoU阈值的AP平均值,具体的就是在0.5 和0.95之间取10个IoU阈值(0.5、0.55、0.6 ... 0.9、0.95)。所以VOC数据集中mAP通常标记为mAP @ IoU=0.5, mAP@0.5 或者 mAP_50,在COCO 数据集中册标记为 mAP @ IoU=0.5:0.05:0.95, mAP @ IoU=0.5:0.95 ...
