Image Transform Node
Image Transform applies visual preprocessing without custom scripting.
Use it to normalize image input before model inference.
Typical Operations
- resize (stretch)
- resize (letterbox)
- rotate
- additional image ops based on runtime capability
Configuration Fields
| Field | Required | Purpose |
|---|---|---|
| Input Image Path | Yes | Payload path containing source image |
| Output Path | Yes | Payload path for transformed image |
| Processing Steps | Yes | Ordered transformation list |
Best Practices
- Match transform settings to model training preprocessing.
- Keep transform pipeline deterministic.
- Store transformed output in separate path from original.
Common Issues
- Distorted inference from wrong resize strategy.
- Empty output due to invalid input image path.
- Performance overhead from unnecessary transform chains.
