Multi-Image Object Detection — Reference-Based Comparison
Traditional detection models analyze each image in isolation. ONE AI's overlap difference approach compares a test image against a reference, letting the model focus only on what changed — dramatically improving accuracy for surveillance and quality control.


Synthetic bird & drone detection dataset — small objects (7–10 % of image), complex city backgrounds, varying lighting. 259 image pairs.
Results
| Model | F1-Score | Model Size |
|---|---|---|
| ONE AI (overlap difference) | 93.2 % | Optimized, lightweight |
| YOLOv8 (single image) | 56.0 % | Pre-trained, heavy |
Key Findings
10× Fewer Errors
ONE AI achieves 93.2 % F1 vs. YOLOv8's 56 % — making more than 10× fewer errors on the same dataset.
Why the Gap Is So Large
By computing pixel-wise differences between reference and test images, ONE AI cancels out complex backgrounds automatically. YOLOv8 must learn to separate tiny objects from busy cityscapes using a single frame — a fundamentally harder problem.
8× Smaller Model
ONE AI's architecture search produces a model 8× smaller than YOLOv8, making it ideal for edge deployment across multiple inspection stations.
Takeaway
When spatially aligned reference images are available, multi-image comparison combined with automated architecture search delivers accuracy that single-image detectors cannot match — at a fraction of the model size.
