Question

我正在尝试使用dlib库基于train_object_detector.cpp示例训练对象检测器。

time ./train_object_detector -tv -u 0 --threads 4 --flip data/training.xml

Loading image dataset from metadata file data/training.xml
Number of images loaded: 78
objective:     45.1205
objective gap: 45.1167
risk:          45.1167
risk gap:      45.1167
num planes:    3
iter:          1

...

objective:     3.44535

risk gap:      0.00889926

Test detector (precision,recall,AP): 1 0 0表示真阳性= 0且假阳性= 0？

此外，当将探测器应用于训练集中的任何图像时，它无法检测到任何对象Number of detections: 0.

如何解决这个问题？
