Haar-tSVD image denoising algorithm offering fast, high-quality noise removal for photographers, media companies, and imaging platforms
Research Paper
Core Innovation
This paper presents Haar-tSVD, a novel image denoising method that integrates global and local patch correlations using a unified tensor-singular value decomposition combined with the Haar transform. Unlike prior methods, it achieves a balance of speed and denoising performance without requiring learned local bases. Additionally, it incorporates adaptive noise estimation through CNN and eigenvalue analysis to improve robustness on real-world images.
