Free vs Licensed Datasets: The Real Business Impact

Platforms like Kaggle, Roboflow and GitHub give you free access to popular computer vision datasets like COCO, ImageNet and Pascal VOC. But do you know exactly what you’re getting?

Free open-source datasets

  • Biased, lower-quality data from unknown sources and with unverified labels
  • Usually image or video only, and often non-domain specific
  • Potentially web scraped, with privacy concerns and unclear copyright

Defined.ai licensed datasets

  • Custom-generated and quality controlled by experts and trusted partners
  • Rich, multimodal and domain-specific for real-world use cases
  • Fully consented, GDPR/HIPAA/ISO compliant and ethically sourced

Image & Visual

Image & Visual

Use object detection datasets to recognize products, vehicles or environments, facial recognition and AI identity verification.

We supported a global tech player to develop their cutting-edge perception system by sourcing over 38K+ ethically sourced first-person images. Collaborating with 300+ international participants, our high-quality data and continually optimized workflows contributed to a 40% reduction in invalidation rates. And because we delivered on-time 100% of the time, the client’s time-to-market went down while the project value went up.

Video & Media

Video & Media

Use multimodal training to combine video, audio and text for next-level generative AI and protect your communities with scalable video content moderation.

A multinational creative software company needed 10,000 hours of high-quality video content, and Defined.ai was ready to meet their volume and deadline demands. With a compliance score of 99.99%, our vast video library controlled for 42 individual technical requirements like resolution, bit rate, frame rate and more. Because getting quality data shouldn’t mean sacrificing ethics, we secured and documented full consent and legal rights for 100% of the content to keep our client risk-free.

Computer vision FAQ

What makes your computer vision datasets different from open-source alternatives?

Our datasets are enterprise-grade, follow strict AI compliance and are curated for real-world use cases like medical imaging and AI disease diagnosis, identity verification and video content moderation.

We are also GDPR and HIPAA compliant, ISO 20071- & 27001-accredited, and every dataset is ethically sourced. All contributors give informed consent, personal information is anonymized and strict data protection protocols are followed. Download the Defined.ai Ethical AI Manifesto

What happens if I need multimodal AI training sets, not just images?

We deliver multimodal datasets that combine video, audio and text, all with custom annotation available. This supports advanced applications from generative AI to scene analysis and real-time moderation.

Isn’t buying data expensive compared to collecting it myself?

In practice, it saves time and money. Collecting and labeling data in-house is resource-heavy, while our datasets are AI-ready and shorten development cycles.
