Two-Step Semiautomated Classification of Choroidal Metastases on MRI: Orbit Localization via Bounding Boxes Followed by Binary Classification via Evolutionary Strategies.

Our orbit localization model identified globes with 100% accuracy and a mean average precision (mAP) of intersection over union thresholds of 0.5-0.95 [mAP(0.5:0.95)] of 0.47 on held-out testing data.

Similarly, the model generalized well to our step 2 data set, which included orbits demonstrating pathologies, achieving 100% accuracy and mAP(0.5:0.95) of 0.44. mAP(0.5:0.95) appeared low because the model could not distinguish left and right orbits.
