Going to read this in depth. I have been on and off trying to find a way to distinguish between in focus, motion blur (camera shake) and out of focus. Motion blur is surprisingly tricky to distinguish using a computer from the others. I can glance at a 2D Fft plot and tell, but the computer - not yet.
- fp64 2y agoBlind Deconvolution is around for a while and from the estimated PSF you can gather the shake pattern (or tell whether it’s just overall out of focus). It just never worked good enough in practice but I remember some impressive results already a decade ago
- porker 2y agoThank you, blind deconvolution and PSF sound like what I have been scratching around the edges of in my experiments, without knowing the right terms to search for to discover prior work. I shall dig into the literature!
