I am analyzing the videos recorded by a surveillance camera and noticed that, in most scenes, there is a sort of "halo" around the right part of people passing by (also around the orange dumpster). Please see the picture below for an example.
I am wondering whether this undesired effect has a name and whether it can be compensated. If so, how?
Although I have no experience in photography, I have some notions of mathematical signal processing. Can I expect that, once this aberration is compensated for, the quality and the sharpness of each frame will improve? I assume it is a sort of "systematic error" that, once recognized, can be "subtracted" so to have sharper images.
