| In this paper, we consider the problem of
similarity between video sequences. Three basic questions are
raised and (partially) answered. Firstly, at what temporal
duration can video sequences be compared? The frame, shot, scene
and video levels are identified. Secondly, given some image or
video feature, what are the requirements on its distance measure
and how can it be easily transformed into the visual similarity
desired by the inquirer? Thirdly, how can video sequences be
compared at different levels? 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. |
