Adaptive Hybrid Algorithm for Spatially Varying Blur
The proposed method integrates Richardson-Lucy deblurring with a novel dual-detection strategy that combines Laplacian variance for local edge sharpness and FFT-based frequency analysis for global texture loss. This hybrid approach enables precise, region-specific blur estimation and restoration, adapting to complex degradations in smartphone-captured document images.
Key steps include initial deblurring using a Gaussian PSF, dynamic blur mask generation, text block detection, and adaptive thresholding for both blurred and non-blurred regions, culminating in a visually coherent and OCR-ready document.
Superior Performance Across Degradation Levels
The HSBDRA method consistently achieves highest F-Measure, PSNR, and SSIM scores across both moderate (Level 1) and severe (Level 2) blur conditions. It outperforms traditional binarization methods (Sauvola, Wolf) which struggle with spatially varying blur, as well as several deep learning baselines in document-specific contexts.
Notably, it exhibits significantly lower Misclassification Error (ME) and Normalized Pixel Misclassification (NPM), demonstrating superior pixel-level accuracy, structural fidelity, and minimal text loss in blurred regions compared to competing approaches.
Enhancing Archival, Legal, and OCR Workflows
This training-free and lightweight framework offers a robust solution for enhancing degraded text documents without requiring extensive datasets or powerful GPUs. Its ability to adapt to non-uniform blur and uneven illumination makes it highly suitable for archival preservation, legal document processing, and improving OCR accuracy on smartphone-captured images.
The adaptive and computationally efficient design also allows for potential integration into modern imaging devices and mobile scanning applications, providing real-time feedback for improved sharpness and automated document enhancement.
