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 by employing a position-dependent point spread function. The approach systematically selects singular values based on a specified energy retention criterion to balance noise amplification and information preservation. Experiments with different motion models demonstrate the algorithm's effectiveness in recovering image details and reducing artifacts. AI
