TL;DR. Abbreviation for Intersection over Union, a metric used in computer vision to measure overlap between bounding boxes.
Technical Definition
Abbreviation for Intersection over Union, a metric used in computer vision to measure overlap between bounding boxes.
How it works
IoU is a commonly used abbreviation for the Intersection over Union metric. This metric is primarily applied in computer vision, particularly in object detection and segmentation tasks, to evaluate the accuracy of predicted bounding boxes or masks against ground truth. It represents the degree of overlap between two regions.
Related Concepts
- Object Detection — A computer vision task that identifies and localizes multiple objects in an image with bounding boxes.
- Computer vision — Computer vision enables computers to interpret and understand information from digital images and videos, automating tasks typically done by human sight.
- Intersection over union (IoU) — A metric measuring the overlap between two bounding boxes, calculated as the intersection area divided by the union area.
