mAP是mean of Average Precision的缩写,意思是平均精确度(average precision)的平均(mean),是object detection中模型性能的衡量标准。object detection中,因为有物体定位框,分类中的accuracy并不适用,因此才提出了object detection独有的mAP指标,但这也导致mAP没有分类中的accuracy那么直观。但也没有那么复杂,本文将详细解...
考虑到离散形式,积分形式变成求和: 因为召回率和精准率都是0到1的值,因此AP也是0到1的值。考虑到我们这只是对某个类(比如人)进行的AP计算,如果考虑到整个数据集中的所有类别(比如人,马,狗等等),分别对每个类别求AP,然后进行平均,我们就得到了mAP(mean Average Precision)。 Interpolated Average Precision 然而,...
Moreover, given a global map, such as a satellite image, our approach can locate and track the targets in geo-coordinates, namely longitude and latitude. The map information is used as a global constraint for compensating the camera motion, which is critical for motion detection on a moving ...

MapDetection has two modes, deep and quick. Quick mode Iterates every process thread, collecting allocation bases from thread starts and instruction pointers. It then scans every unique allocation base for any anomalies. Deep mode Run quick scan, then traverse the virtual memory space for any exe...
mAP: mean Average Precision, 即各类别AP的平均值 github上面有一个关于MAP计算的MAP链接,可能能更好的帮助你理解MAP 在评测时,COCO评估了在不同的交并比(IoU)[0.5:0.05:0.95]共10个IoU下的AP,并且在最后以这些阈值下的AP平均作为结果,记为mAP@[.5, .95]。 而在Pascal VOC中,检测结果只评测了IOU在0.5这...
