Video Shot Detection
Camera break detection; Shot boundary detection
Shot is a contiguous sequence of video frames with smooth and continuous camera motion. Shot can thus be viewed as an uninterrupted video frame sequence of space, time, and graphical configuration. The boundary between two shots is called a camera break (or video edit). Based on the transitional properties of video edits, there are two major types of camera breaks: cut and gradual transition. A camera cut is an instantaneous change from one shot to another. The gradual transition can further be categorized as wipe and dissolve. A wipe is the moving transition of a frame (or a pattern) across the screen that enables one shot to gradually replace another. A dissolve superimposes two shots, where one shot gradually appears while the other fades out slowly. Fade-in and fade-out can be considered as the special cases of dissolve, by replacing one of the shots as a constant image sequence (e.g., black image sequence). In...
