Abstract:
|
This paper addresses the problem of video summarization
through an automatic selection of a single representative
keyframe. The proposed solution is based on the mutual reinforcement
paradigm, where a keyframe is selected thanks to its
highest and most frequent similarity to the rest of considered
frames. Two variations of the algorithm are explored: a first
one where only frames within the same video are used (intraclip
mode) and a second one where the decision also depends
on the previously selected keyframes of related videos (interclip
mode). These two algorithms were evaluated by a set of
professional documentalists from a broadcaster’s archive, and
results concluded that the proposed techniques outperform the
semi-manual solution adopted so far in the company. |
