Technical Description
This invention automatically generates a pan shot from a video by calculating inter-frame object displacement and relative depth through foreground correlation across consecutive video frames. These frames are then deblurred, rewarped using homographies, and averaged to produce a final output featuring a sharp, static foreground against a motion-blurred background.
Problems Addressed
- Object’s Velocity Guess Beforehand
