Probabilistic Object Detection: Definition and Evaluation

December 2019

tl;dr: Proposes a new metric for probabilistic detection.

Overall impression

Proposed a benchmark PDQ (probabilistic detection quality) to evaluate probabilistic object detectors.

\[PDQ = \sqrt{DQ * LQ}\]

\(DQ = \exp(-(L_{FG} + L_{BG}))\) \(L_{FG} = -\frac{1}{|GT|}\sum \log p(TP)\) \(L_{BG} = -\frac{1}{|GT|}\sum \log (1 - p(FP))\) \(LQ = p(class=y)\)
