title: Precision-Recall Curve in Tensorflow Object Detection API
body: <p>Is there a way to visualize the Precision-Recall Curve in the Tensorflow Object Detection API?
  I know that the mAP represents absolute value of the area under the curve, but i think the actual curve would be more representable for my application?
  I already found some precision and recall values within the utils/metrics<a href="https://github.com/tensorflow/models/blob/master/object_detection/utils/metrics.py" rel="nofollow noreferrer">1</a>, but I don't know what they represent exactly, or better said, how to generate a Prec/Recall Curve out of them.
  Can somebody help me, how to do that?</p>
