"WebOur goal here is to accurately estimate the Point Spread Function - PSF, that models the intrinsic camera blur. This function can be locally interpreted as the response of the camera to a point light source. In [1] we presented a theoretical study proving that the sub-pixel PSF estimation problem is well-posed even with a single image capture ... " - Fftwf_plan_r2r_2d
