VisualGREP research considers the problem of similarity between video sequences.
The frame, shot, scene and video levels are identified. A general approach based on either a set or sequence representa tion with variable degrees of aggregation is proposed and applied recursively over the different levels of temporal res olution. It allows the inquirer to fully control the importance of temporal ordering and duration. The general approach is illustrated by introducing and discussing some of the many possible image and video features. Promising experimental results are presented.
