⑤ mean_ap(Mean average precision,mAP):所有类的平均AP的平均值。如图19所示。在训练期间或对不同模型进行比较时,采用'mean_ap'来评估检测模型的性能。 图(19) 三个IoU阈值的示例评估结果
mAP是英文mean average precision的缩写,意思是平均精度均值,这个词听起来有些拗口,我们来仔细捋一捋。上面我们知道了什么是AP,AP就是PR曲线下面的面积(如下图),是指不同召回率下的精度的平均值。 然而,在目标检测中,一个模型通常会检测很多种物体,那么每一类都能绘制一个PR曲线,进而计算出一个AP值。那么多个...

For this reason, the AP value depends on the class and on the IoU threshold. You can obtain the specific AP values, the averages over the classes, the averages over the IoU thresholds, and the average over both, the classes and the IoU thresholds. The latter one is the mean average...

Because of a bug fix regarding the calculation of the mean average precision (mean_ap) measure during the evaluation of deep-learning-based object detection, the deep-learning-based object detection evaluation results might be different. To obtain the same results for 'mean_ap' as before, the ...
