Does anyone know software to undistort images and messure within them on a slanted plane by marking a circle of known radius?
i have images of almost all >100 Elna discs and i want to digitize them. i only have access to 24 of them.
Searched a bit around and could not find a good all in one solution yet, or at least none with sufficient information from skimming its description/documentation
plz
