Data Annotation Services for Reliable and Scalable AI Training
Data Annotation Services
DataVLab provides advanced data annotation services for teams building computer vision, multimodal, and AI systems that depend on highly accurate training datasets. Our workflows combine skilled human annotators, domain specialists, and targeted QA processes to deliver consistent labels at scale.From complex polygon segmentation to multi-sensor fusion workflows, we structure your data so your models learn faster, generalize better, and perform reliably in production environments. Every project is supported by transparent communication, secure infrastructure, and flexible scaling options designed for startups and enterprise AI teams alike.Whether you need a dedicated long-term workforce or rapid annotation for a proof of concept, DataVLab adapts to your timeline, quality requirements, and technical constraints including EU-only staffing for sensitive data.
High-quality labels across image, video, audio, and multimodal datasets.
Human-in-the-loop QA and domain-aware review for complex projects.
Flexible scaling options with EU-only teams available for sensitive data.
How Our Data Annotation Services Support Your AI Roadmap
From early proof-of-concept datasets to production-scale pipelines, we design annotation workflows that align with your model objectives, edge cases, and operational constraints.
High-Quality Image Dataset Annotation
Pixel-accurate labels for computer vision training
We annotate image datasets across bounding boxes, polygons, semantic segmentation, keypoints, lane markings, and domain-specific taxonomies. DataVLab supports both simple and highly complex visual tasks, including medical imaging, retail intelligence, smart cities, and industrial inspection.
Advanced Video Annotation Workflows
Temporal consistency and object tracking across frames
Our video teams specialize in ID tracking, multi-object trajectories, frame-level segmentation, and event-based labeling for safety, autonomous systems, and behavior analysis. We ensure temporal coherence with multi-layer QA to prevent ID switches and drift.
Multimodal & Sensor Fusion Annotation
Camera, LiDAR, radar, and depth data aligned into unified scenes
DataVLab handles annotation across heterogeneous sensor inputs, from 3D point clouds to radar signatures. We build synchronized labeling pipelines for ADAS, robotics, geospatial mapping, and infrastructure inspection use cases.
Domain-Specialist Annotation & Quality Review
Expert-level validation for sensitive or high-precision datasets
Some projects require medical reviewers, engineers, or domain-expert annotators. We provide specialist teams when accuracy cannot rely solely on generalist labor—such as MRI segmentation, biological imaging, fiber-optic infrastructure, or industrial quality control.
Scalable Human-in-the-Loop QA
Multi-stage review workflows for production-ready datasets
Every dataset passes through tailored QA stages, including consensus review, targeted spot checks, ontology validation, and automated consistency scripts. This ensures reliability even in high-volume or long-term annotation programs.
