I often go to presentations and take photos of slides. Sometimes I sit too far, and photos come out blurred or noisy.
It is known that if to take N photographs of the same object from exactly the same point in the same lighting conditions, and to average them pixel-wise, this would denoise them and would improve the apperant quality.
However, in case of photographs taken with a cellphone by hand they (1) will be slightly offset or rotated because of hand movements, (2) might have some areas obscured in some of them.
My question is: "Is there a linux software that is able to take, say, 2-10 photos of the same slide, find the most likely offsets/rotations, compansate for them and for obscured areas, and improve image quality?"

? It would be easier to sit closer, get a tabletop tripod, or ask the presenter for a copy of the slides. \$\endgroup\$
