Abstract

Automatic video summarization aims to provide brief representa- tion of videos. Its evaluation is quite challenging, usually relying on comparison with user summaries. This study views it in a diferent perspective in terms of verifying the consistency of user summaries, as the outcome of video sum- marization is usually judged based on them. We focus on human consistency evaluation of static video summaries in which the user summaries are evalu- ated among themselves using the consistency modelling method we proposed recently. The purpose of such consistency evaluation is to check whether the users agree among themselves. The evaluation is performed on diferent pub- licly available datasets. Another contribution lies in the creation of static video summaries from the available video skims of the SumMe datatset. The results show that the level of agreement varies signigcantly between the users for the selection of key frames, which denotes the hidden challenge in automatic video summary evaluation. Moreover, the maximum agreement level of the users for a certain dataset, may indicate the best performance that the automatic video summarization techniques can achieve using that dataset.
