This research from the Shenzhen Institute of Advanced Technology introduces an Adaptive Dual-Network (ADNet) framework for fast QR code motion deblurring, which employs an edge-guided Transformer and a lightweight network with an intelligent blur-severity routing mechanism. The framework prioritizes QR code decodability and achieves a 90% decoding rate while reducing average inference time by 19% compared to using a single powerful network.
Key insights
- Explicitly guiding deep learning models with domain-specific priors (like QR code sharp edges) via edge-guided attention is more effective for task-specific performance (decodability) than general image quality metrics.
- An adaptive, dual-network architecture can effectively balance high deblurring performance for severely degraded inputs with significantly improved inference efficiency for mildly blurred ones.
- Laplacian Variance provides a robust and efficient metric for dynamically estimating blur severity, enabling intelligent routing in an adaptive deblurring framework.
