Constrained iterative blind deconvolution

摘要

An image processing method is applied on an image of a target or on a segment thereof. A deconvolution procedure (S1) includes a blind deconvolution of the whole image or segment to estimate a point spread function characterizing the imaging process and a target function characterizing the distribution of reflectors and scatterers in the target. The deconvolution is an iterative blind deconvolution. The target function and the point spread function are estimated and updated by alternating between two equations. At least one constraint is enforced at each iteration. An image processing unit (10) and an image processing apparatus (1) are also provided.
