+Protocol: CCPD official detection metric (Xu et al., ECCV 2018). One box per image is correct iff IoU > 0.7. `Overall` is precision on the union of the six official test subsets (DB, Blur, FN, Rotate, Tilt, Challenge). LPD-YuNet does not publish a claimed accuracy; numbers below are measured with OpenCV DNN.
