Hi Jonathan Hui,

Great article, but you didn’t described what approach is used in MS COCO: 11-Recall-points or Area-Under-Curve.

It would be nice, if you add that MS COCO uses 101-Recall-points approach:

So:

  1. MS COCO — uses 101-Recall-points on PR-chart.
  2. PascalVOC2007 — uses 11-Recall-points on PR-chart.
  3. PascalVOC2010–2012 — uses Area-Under-Curve on PR-chart.
  4. ImageNet — uses Area-Under-Curve on PR-chart.
