In image processing, what is real time?

Question

in image processing applications what is considered real time? Is 33 fps real time? Is 20 fps real time? If 33 and 20 fps are considered real time then is 1 or 2 fps also real time?

Can anyone throw some light.

Answer 1

In my experience, it's a pretty vague term. Often, what is meant is that the algorithm will run at the rate of the source (e.g. a camera) supplying the images; however, I would prefer to state this explicitly ("the algorithm can process images at the frame rate of the camera").
