Skip Manual Labeling: How You Can Automatically Caption Images with Spacial Awareness for Any Product
Have you ever stared at thousands of product images, dreading the manual labor of tagging each one for AI training?
Capturing every nuance by hand is a daunting (and expensive) task.
Yet structured annotations are the lifeblood of machine learning.
The rule is simple: garbage in, garbage out.
A high quality image caption needs to capture:
- Exact object locations in complex scenes
- Relationships with surrounding elements
- Environmental context and lighting conditions
- Consistent descriptions at scale
That's exactly where our client found themselves - facing 10,000+ images of custom textured walls that needed precise labeling for fine-tuning a diffusion model.
Using a combination of Florence 2, GPT-4o Vision, and the Instructor library, you'll see how to build a reliable system that:
- Automatically detects and localizes objects
- Generates structured, validated descriptions
- Handles spatial relationships systematically
- Scales from 50 to 50,000+ images without compromising quality
Best of all? We did it without any custom models or infrastructure.
Here's the complete technical breakdown of how we turned a month-long manual process into an automated pipeline that runs in hours.
