Overview

Become a certified Image Segmentation professional.

Semantic segmentation overlay colouring a farm scene by class: sky, trees, field and a tractor carrying a DeeLab label

Segmentation is labelling at the pixel: not a box around the car but its exact outline, not roughly where the road is but precisely which pixels are road.

It is the work behind medical imaging, autonomous driving and any system that needs to know shapes rather than positions, and it pays for patience and precision above everything else.

This course is five days with a live trainer. Day one grounds you in semantic segmentation and its foundational concepts; day two covers polyline annotation in the tools; day three is hands-on polygon segmentation with trainer support; day four is trainer-led mask-based annotation. You work in Label Studio or CVAT on real imagery, building the edge discipline that separates usable masks from rejected ones. Day five is a practical competency evaluation with your trainer, and passing it earns the certificate.

One of the six courses of the Certified Data Annotator programme: each one you pass counts toward the credential, and completing all six earns it. Available on its own or as part of the programme, with the certificate included on passing the assessment.

Frequently Asked Questions

Everything you need to know about this course.

The course is open to anyone. No prior AI knowledge or coding experience is needed. It works well for project managers and QA leads overseeing teams that do pixel-level work, contractors and freelancers who annotate segmentation data professionally, and developers or researchers building computer-vision products where scene understanding (not just object detection) is the goal. Understanding segmentation from the inside helps you plan better, communicate across teams, and produce higher-quality results faster.

All the tools in the course are free or low cost, and you can keep using them after the course ends. You will work with Label Studio (Community Edition) or CVAT (Community Edition) for polygon, polyline, and pixel-level mask annotation, and Google Drive for dataset organisation. A standard laptop with a modern browser is all you need.

You will be able to produce polygon, polyline, and pixel-level mask annotations to production standards on real image datasets, follow a clear label taxonomy and edge-case guidelines so your output is usable downstream, and meet the precision and consistency expectations production teams set for segmentation work. These are the day-one skills used inside medical imaging, satellite analysis, autonomous driving, and any AI that needs to understand a scene rather than just spot it. Project scoping, QA leadership, and team-role rotation are reserved for the Advanced courses and bootcamps.

Yes. Image Segmentation Essentials is fully online, and you can join from anywhere in the world. We are also open to designing on-site workshops for organisations with sufficient demand; reach out through our contact page if you would like an in-person format for your team.

There is currently no formal industry-wide certification body for data annotation training. The AI industry has not yet filled that gap. DeeLab Academy follows the best current industry practices and methodologies, our curriculum is designed and delivered by a five-member team of multi-year industry experts, and we collect structured feedback from every cohort to keep improving the content. We are fully open to being audited by any recognised consultancy that wishes to validate our processes.

No. This course teaches skills and gives you a certificate when you pass. It does not place you in work or guarantee income.

You have three months to complete the course, counted from the day you sign up. That applies whether the course is self-paced or runs to a schedule. The deadline is fixed from your sign-up date and doesn't reset if you move to a later run.

Yes, you're automatically enrolled in the run you choose, and you can move to another scheduled run of the same course up to twice from your dashboard. Your payment carries over, and your completion deadline does not change because it runs from the day you signed up.
