Shot Change Detection Using Scene-Based Constraint

摘要

A step for managing a large video database is to partition the video sequences into shots. Past approaches to this problem tend to confuse gradual shot changes with changes caused by smooth camera motions. This is in part due to the fact that camera motion has not been dealt with in a more fundamental way. We propose An approach that is based on a physical constraint used in optical flow analysis, namely, the total brightness of A scene point across two frames should remain constant if the change across two frames is a result of smooth Camera motion.
