Video Annotation for AI Pro: Segmentation, Actions, 3D and Leading Quality

The specialist work that pays more: pixel masks across frames, keypoints and pose, action timelines, 3D cuboids, multimodal video, agreement metrics, reviewing others and running an annotation team.

About this course

Boxes get you in the door; the specialist work is where video annotation becomes a career. This course takes an annotator who already tracks objects and teaches the harder, better-paid layers: semantic, instance and panoptic segmentation and how to keep masks consistent across frames; keypoints and pose for sports and health; temporal and action annotation with clean start and end boundaries; 3D point-cloud cuboids and what a LiDAR annotator actually does; audio-visual and multimodal video where Nigerian speech and scenes give Nigerian annotators an edge; handling ambiguity with a decision log; measuring quality at scale with inter-annotator agreement, gold sets and tracking metrics; being the reviewer whose feedback makes a team better; writing the guideline and running the team; and the data-protection and bias questions every dataset raises under the Nigeria Data Protection Act. Chidinma, now a QA reviewer at a Lagos AI-data company, becomes a team lead by the last lesson. Take the Video Annotation for AI course first, or arrive with real box-and-track experience. Free, like every Skillnaija course.

Eighteen months after her first bounding box, Chidinma Okoye sits in the Yaba office of Naija Vision Labs with a new title on her email signature: QA Reviewer. This morning Mr Bassey Etim drops three project briefs on her desk. A Lekki estate wants every person and vehicle in its camera footage outlined to the pixel, not boxed. A Lagos football academy wants the joints of every player marked so software can study their running style. An Abuja ride-hailing company wants the exact second each near-miss begins and ends in thousands of dashcam clips. 'None of this is box work,' Mr Etim says. 'The client is paying more, and they are asking for fewer, better people. I want you to learn all three and then teach the team.' Chidinma looks at the briefs and realises that the skill she has is the floor, not the ceiling.
