Quasi-SVD enables real-time imaging with faster matrix factorization

Researchers have developed Quasi-SVD, a novel matrix factorization technique designed for real-time imaging applications. Unlike traditional Singular Value Decomposition (SVD) which is sequential and slow on GPUs, Quasi-SVD uses soft constraints on one factor and exact orthogonality on another, allowing for efficient parallelization. This method achieves high reconstruction fidelity (SSIM of 0.89-0.94) and significantly accelerates computation, reaching speeds of over 25 FPS. The framework has demonstrated robust performance in medical imaging tasks such as ultrasound localization microscopy and Mueller matrix polarimetry, enabling live image-guided workflows previously unachievable with classical solvers.
