Infrared Image Detail Enhancement Algorithm Based on Guided Filtering and Adaptive Dual-Gamma Nonlinear Mapping
This paper proposes a novel infrared image detail enhancement framework combining guided filtering, adaptive non-local mean filtering, and adaptive dual-gamma nonlinear mapping to address issues of low contrast, blurred details, and noise in infrared images. The method decomposes images into base and detail layers, suppresses noise using adaptive non-local mean filtering, and enhances details with a dual-gamma function, finally fusing the layers. Experimental results show significant improvements in GE, SSIM, and PSNR over state-of-the-art methods, effectively enhancing fine details while suppressing artifacts and noise.

The proposed algorithm leverages guided filtering for image decomposition, adaptive non-local mean filtering for noise suppression, and dual-gamma nonlinear mapping for detail enhancement. This synergistic approach aims to balance noise reduction and detail preservation across varying dynamic ranges.
Comprehensive benchmarking on self-built and public datasets demonstrates the superiority of our method over state-of-the-art approaches across multiple metrics, including gradient entropy (GE), structural similarity index (SSIM), and peak signal-to-noise ratio (PSNR). Subjective evaluations also confirm improved visual quality and detail preservation.
The current framework relies on fixed parameter settings for fusion coefficients and gamma. Future work will focus on developing adaptive parameter selection mechanisms based on image statistics or data-driven analysis, exploring adaptive window scaling for extreme noise conditions, and incorporating global brightness correction strategies for enhanced robustness and visual consistency.

Enhanced Visibility in Surveillance Imagery
In a critical surveillance scenario, raw infrared footage suffered from severe blurring and low contrast due to environmental interference. Deploying the proposed algorithm, the system successfully enhanced fine details such as license plates and facial features, which were previously indistinguishable. This led to a 30% improvement in object recognition accuracy and significantly reduced false alarms, demonstrating the real-world impact of advanced image enhancement for security applications.
