Abstract
Video sequence processing with various filtering rules is applied to extract dominant spatial features and generate unique set of signatures describing video content. Accurate active regions are determined for each video sequence frame. Subsequently, a video sequence is structured by tracking statistical changes in the content of a succession of video frames, and suitable frames are selected for further spatial processing. Selected video frames are processed for feature extraction and description, and compact representative signatures are generated, resulting in an efficient video database formation and search.
