Intersection over detection

WebThe accuracy of an object detection model depends on the quality and number of training samples, the input imagery, the model parameters, and the requirement threshold for accuracy. The Intersection over Union (IoU) ratio is used as a threshold for determining whether a predicted outcome is a true positive or a false positive. WebMar 22, 2024 · Generalized Intersection over Union . Intersection over Union is the most popular evaluation metric used in object detection benchmarks. It has been shown that Intersection Over Union can be used as the objective function in object detection algorithms. Hence, our objective here would be to maximize the Intersection over Union.
