System for automatic video segmentation and key frame extraction for video sequences having both sharp and gradual transitions

Image Number 11 for United States Patent #5635982.

An automatic video content parser for parsing video shots such that they are represented in their native media and retrievable based on their visual contents. This system provides methods for temporal segmentation of video sequences into individual camera shots using a novel twin-comparison method. The method is capable of detecting both camera shots implemented by sharp break and gradual transitions implemented by special editing techniques, including dissolve, wipe, fade-in and fade-out; and content-based key frame selection of individual shots by analyzing the temporal variation of video content and selecting a key frame once the difference of content between the current frame and a preceding selected key frame exceeds a set of preselected thresholds.
