For detection, a common way to determine if one object proposal was right is Intersection over Union (IoU, IU). This takes the set A of proposed object pixels and the set of true object pixels B and calculates: Commonly, IoU > 0.5 means that it was a hit, otherwise it was a fail.

SpletmAP: Mean Average Precision for Object Detection A simple library for the evaluation of object detectors. In practice, a higher mAP value indicates a better performance of your detector, given your ground-truth and set of classes. Install package pip install mean_average_precision Install the latest version SpletAs the name suggests, mAP is calculated by taking a mean value from Average Precision scores. So, to understand mAP, you must first understand the Average Precision concept.
