Making the Discrete Continuous: Synthetic RAW Augmentations for Fine-Grained Evaluation of Person Detection Performance in Low Light

arXiv:2605.22455v1 Announce Type: cross Abstract: Real-world deployment of AI vision models is both fueled and limited by the data available for training and testing. Real datasets are sparse and uneven: long-tailed or unbalanced distributions hinder generalization, and the low number of samples in low density regions makes it hard to run evaluations. Synthetic data can fill these gaps, providing us with a way to sample the input space more continuously and improve data coverage for benchmarks. Focusing on the autonomous driving safety-critical case of pedestrian detection in the dark, we show

Why this matters
Why now

The increasing reliance on AI vision models in safety-critical applications like autonomous driving, combined with the inherent limitations of real-world data, is driving innovation in synthetic data generation.

Why it’s important

This development addresses a fundamental constraint in AI model development and evaluation, enabling more robust and reliable AI systems, particularly in challenging environments like low light.

What changes

The ability to generate synthetic RAW augmentations continuously improves the fine-grained evaluation of AI models, shifting from discrete, sparse real data to a more comprehensive synthetic alternative.
