【问题描述】：

我正在使用 dlib 库（使用 python2）在静态图像中进行人脸检测，如果检测到的人脸的概率/质量较低，我想丢弃这些人脸。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人脸质量的指标会有所帮助。

【参考方案1】：

从official example中提取：

# 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]))

c++可以吗？
