In your paper, you used Joint Detection Rate (JDR) to measure the 2D pose estimation accuracy. But as I observe, the JDR metric is very similar to the PCK metric using headsize (a.k.a. PCKh). So I am wondering what is the difference between JDR and PCK. BTW, I didn't see JDR was used earlier than your paper, so it was proposed in your paper for the first time, right? :)
