1、PCK - Percentage of Correct Keypoints -----关键点正确估计的比例
计算检测的关键点与其对应的groundtruth间的归一化距离小于设定阈值的比例(the percentage of detections that fall within a normalized distance of the ground truth).
------------ PCK Evaluation: Single_People -------------
Parts & Ankle & Knee & Hip & Wris & Elbo & Shou & Head & Mean
PCK & 93.2 & 88.3 & 70.4 & 92.1 & 92.6 & 94.6 & 95.9 & 89.6
2、PCKh
FLIC 中是以躯干直径(torso size) 作为归一化参考.
MPII 中是以头部长度(head length) 作为归一化参考，即 PCKh.
3、 PDJ - Percentage of Detected Join ----- 检测到的关键点比例.
