Blind single-frame deconvolution by tangential iterative projections (TIP)
Abstract
Deconvolution serves as a computational means of removing the effect of optical aberrations from recorded images and is employed in many technical and scientific fields of study. In most imaging scenarios the nature of the blurring kernel or point-spread function (PSF) of the imaging system is unknown and both the object and PSF can be estimated using different forms of mathematical optimisation. The Tangential Iterative Projections (TIP) algorithm is a multi-frame deconvolution framework where multiple images can be combined to obtain a single estimate of the object. It is shown here that this framework may be also used for single-frame deconvolution with a few modifications to the algorithm. This step from multiple to one frame is non-trivial and greatly improves the applicability of the TIP framework to most imaging scenarios.
