Abstract: Image deblurring with blurred/noisy image pairs is described. In one implementation, a system combines a blurred image with a corresponding noisy image of the same subject to create a high-quality deblurred image. The blurred/noisy image pair can be acquired by an inexpensive hand-held camera, e.g., in unfavorable low light conditions. An exemplary iterative process uses the blurred image and the noisy image at each step to produce the high-quality image. First, the system estimates the blur kernel of the blurred image using information from both the blurred and noisy images. Then, the system performs residual image deconvolution, which favors suppression of ringing artifacts. Finally, the system applies gain-controlled deconvolution to suppress remaining ringing artifacts in smooth image regions. The system iterates these steps to obtain the final high-quality image.
