Blind Deblurring and Deconvolution

Many imaging systems in use today acquire data that are related to a desired object function f(·) through the linear relationship where h(·,·; θ) is the point-spread function for the imaging system, and θ is a collection of system parameters – some or all of which may be unknown – that characterize the system and, hence, its point-spread function. In some situations, only a small number of parameters might be required for the characterization of the system, whereas in other situations, the parameters that characterize the system might be made up of the point-spread function’s point-by-point values for all x and y of interest.
