Image segmentation

How it is used

Semantic segmentation labels each pixel by class (road, sky, person); instance segmentation also separates individual objects (person 1, person 2). Used in medical imaging, satellite images and self-driving cars. The output is usually called a mask.

Example sentences

1. We use image segmentation to measure the exact size of each tumor on the scan.

2. Labeling data for image segmentation takes much longer than drawing boxes.

Related terms

• object detectionA computer vision task that finds objects in an image or video and gives both their class, such as 'car' or 'person', and their position, usually as a box.
• computer visionThe area of AI that teaches computers to understand images and video, for example recognizing objects, reading text in photos or tracking movement.
• 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.
• annotationThe work of adding labels or notes to raw data, such as drawing boxes around objects in images or marking the topic of each sentence, so that it can be used for training or evaluation.
