Visual Label Reference¶
Purpose: Inline example gallery for the current Label Studio class set Rule of use: These images are visual anchors for consistency. The schema definitions still live in Label Studio Schema.
How To Use This Page¶
- Use this page when two annotators are unsure how large a region should be.
- Use the smallest meaningful object a reviewer would name in one phrase.
- When in doubt, prefer the schema's object boundary over a visually tempting but lower-level box.
