I'm waiting for your ideas, mainly on how to treat uncovering of areas

Ideas working out hidden areas.

Try to imagine a static background. Maybe a landscape.

now small object drives between camera and background from left to right

everyframe, the object moves from left to right, you have to replace the leaved space with the background (this would the way, our brain is working)

you could do that with a motionmask, that says: "this area was static a frame before / is static the next frame)"

now imagin the background is panning (direction irrelevant, for now)
a normal motionmask will fail, BUT a motioncompensated motionmask will work!

compensate, lets say 5 frames, to the same temporal postion, build a motionmask, and figure out the areas, gone static within those 5 frames. Those pseudostatic areas can then be used to fill the uncovered areas.

I hope that wasn't to irritating, trying to make the best out of my crappy english knowledge
