Definition
Blind image deconvolution is the problem of recovering a sharp image (such as that captured by an ideal pinhole camera) from a blurred and noisy one, without exact knowledge of how the image was blurred. The unknown blurring operation may result from camera motion, scene motion, defocus, or other optical aberrations.
Background
A correct photographic exposure requires a trade-off in exposure time and aperture setting. When illumination is poor, the photographer can choose to use a long exposure time or a large aperture. The first setting results in motion blur when the camera moves relative to objects in the scene during the exposure. The second setting results in out-of-focus blur for objects at depths away from the focal plane. Furthermore, these effects may be exacerbated by the user due to camera shake, incorrect focus...
