PROBE (Progressive Removal of Blur Residual) is a recursive framework for blind deblurring. PROBE is neither a functional minimization approach, nor an open-loop sequential method where blur kernel estimation is followed by non-blind deblurring. PROBE is a feedback scheme, deriving its unique strength from the closed-loop architecture. Thus, with the rudimentary modified inverse filter at its core, PROBE's performance meets or exceeds the state of the art, both visually and quantitatively. Remarkably, PROBE lends itself to analysis that reveals its convergence properties.
