如果检测到的人脸的概率/质量较低,我想使用dlib库(包含python2)在静态图像中进行人脸检测,我想放弃这些人脸。因此我想要一个函数来给出检测到的人脸的概率。或者另一个可用于丢弃质量的度量标准将会很有帮助。在dlib中获取检测到的人脸的概率

提取的official example:
# Finally, if you really want to you can ask the detector to tell you the score
# for each detection. The score is bigger for more confident detections.
# The third argument to run is an optional adjustment to the detection threshold,
# where a negative value will return more detections and a positive value fewer.
# Also, the idx tells you which of the face sub-detectors matched. This can be
# used to broadly identify faces in different orientations.
if (len(sys.argv[1:]) > 0):
img = io.imread(sys.argv[1])
dets, scores, idx = detector.run(img, 1, -1)
for i, d in enumerate(dets):
print("Detection {}, score: {}, face_type:{}".format(
d, scores[i], idx[i]))
