WebLearning Generalized Intersection Over Union for Dense Pixelwise Prediction is the evaluation itself. Learning a metric sensitive loss function has proven to be better than a default option e.g. a standard cross-entropy loss (Yu & Blaschko, 2015; Yu et al., 2016; Berman et al., 2024; Rezatofighi et al., 2024; Zheng et al., 2024). WebIn such a case: Area of Overlap: 5 * 5 = 25;; Area of Union: Area of the Red Bounding Box + Area of the Green Bounding Box - Area of Overlap = 10 10 + 10 10 - 25 = 175; IoU: Area of Overlap / Area of Union = 25 / 175 ~ 0.14 - poor IoU; Code implementation .
