Line scan camera image processing for train photography

Line scan sensors are basically just scanners, heck people make em out of scanners .

Usually the issue is they need rather still subjects, but in this case rather than the sensor doing a scanning sweep they're just capturing the subject as it moves by, keeping the background pixels static.

It only works for trains because the image of train at t+1 is basically image of train at time t shifted over by a few pixels, right? It doesn't seem like this would work to capture a picture of a human, since humans don't just rigidly translate in space as they move.

If the human is running and doesn't frantically shake it decently works. There's samples of horse race finishing line pics in the article, and they look pretty good IMHO.

It falls apart when the subject is either static or moves it's limbs faster than the speed the whole subject moves (e.g. fist bumping while slowly walking past the camera would screw it)

Depends what you're going for.
