ABSTRACT
|
| A video content representation framework is proposed in this paper for extracting limited but meaningful information of video data directly from MPEG compressed domain. A hierarchical color and motion segmentation scheme is applied to each video shot, transforming the conventional frame-based representation to a feature-based one. Then, all features are gathered together using a fuzzy formulation and extraction of several key frames is performed for each shot in a content-based rate sampling framework. In particular, our approach is based on minimization of a cross-correlation criterion among video frames of a given shot, so as to be located a set of minimally correlated feature vectors.
