Estimating Camera Motion from a Single Motion-Blurred Image
- InDubioProRubio 2y agoThree days after posting- gets inverted and reused as a directional camera motion blur shader ever after
- drsopp 2y agoIsn't a logical next step to extract the depth field? Possible?
- wiz21c 2y agoI'm not familiar with all of this but is there then a tool to remove the blur ?
- xattt 2y agoThat’s for the next grad student to solve.
- atoav 2y agoDeconvolution can be used for this, also see this currated list of resources: https://github.com/CVHW/Deblurring https://github.com/CVHW/Deblurring
- wiz21c 2y agoThis list is so big and goes so much in the past...
- esafak 2y agoYes, those have existed for decades, with various degrees of success.
- Imustaskforhelp 2y agoCan this be used in LLM's like gemini which don't really have a motion idea but rather they just take things frame by frame and so can't really understand motion b/w them
- anovikov 2y agoCan't upvote this enough. Finally a piece that's not about LLMs or how are they going to ruin the world.
- fortran77 2y agoAnd not about Rust, either!
- damnitbuilds 2y agoAnd no cod psychology about how to live a better life, either!
- dylan604 2y agoor worse, make the world a better place
- bsenftner 2y agoVisual effects, VFX, has been doing this type of work for decades. The guy that I know doing this the best, Eugene Vendrovsky ended up at Nvidia as a robotics computer vision division director. Back in the early 2000's he had all kinds of camera motion recovery algorithms we used in the Tracking department for use on feature films like the live action Scooby Doo, Riddick and the Narnia films. Eugene retired recently, after a very productive career.
- porker 2y agoGoing 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!
- DrNosferatu 2y agoDoesn’t the Point Spread Function already achieve this? https://en.m.wikipedia.org/wiki/Point_spread_function https://en.m.wikipedia.org/wiki/Point_spread_function
