Researchers have developed a new framework using singular value decomposition (SVD) to restore images affected by shift-variant motion blur. This method addresses the challenge of varying degradation across an image, which cannot be handled by a single convolution kernel. The approach utilizes a singular-value energy retention criterion to manage noise amplification while preserving image details. Experiments show the SVD-based algorithm effectively recovers image information and reduces artifacts caused by different motion models. AI
