The Complete Guide to Image Annotation for Computer Vision

Image annotation is crucial for training AI-based computer vision models. It involves manually labeling and annotating images in a dataset to train artificial intelligence and machine learning computer vision models. The goal of image annotation is to accurately label and annotate images that are used to train a computer vision model. There are four most commonly used types of image annotations: bounding boxes, polygons, polylines, key points. Challenges in the image annotation process include maintaining consistent data, dealing with inter-annotator variability, balancing costs with accuracy levels, and choosing a suitable annotation tool. Best practices for image annotation for computer vision projects include ensuring raw data is ready to annotate, understanding and applying the right label types, creating a class for every object being labeled, and using a powerful user-friendly data labeling tool.
