Labeling Images Fast: Active Learning Tactics

Labeling images for computer vision models used to be slow, costly and overwhelming — but it doesn’t have to be anymore. In this blog post, we dive into modern active learning tactics, human-in-the-loop (HITL) workflows and semi-supervised learning techniques that help you slash annotation costs by 30–70% without sacrificing data quality. Learn how to build a lean, scalable labeling pipeline using confidence sampling, smart review structures, cloud vision APIs for pre-labeling and serverless automation. Whether you’re creating object detection models, fine-tuning OCR pipelines, or launching custom AI solutions, mastering these strategies will help you deliver better results, faster and cheaper, while setting your AI projects up for long-term success.
