Object detection

How it is used

Used in traffic cameras, retail shelves, factory inspection and self-driving cars. Engineers talk about detectors, bounding boxes, confidence scores and mAP (mean average precision). It goes further than image classification, which gives one label per image.

Example sentences

1. Our object detection model misses people who are partly hidden behind cars.

2. For object detection we need boxes, not just one label per photo.

Related terms

• bounding boxA rectangle drawn around an object in an image and stored as coordinates, showing where the object is. It is the standard output of object detection.
• computer visionThe area of AI that teaches computers to understand images and video, for example recognizing objects, reading text in photos or tracking movement.
• CNNShort for convolutional neural network: a network that slides small learned filters over an image to detect patterns such as edges, textures and shapes.
• image segmentationA computer vision task that labels every pixel of an image with a class or an object, giving exact shapes instead of rough boxes.
