ABSTRACT
The advances in digital video technology and the ever increasing availability of computing resources have resulted in the last few years in an explosion of digital video data, especially on the Internet. However, the increasing availability of digital video has not been accompanied by an increase in its accessibility. This is due to the nature of video data, which is unsuitable for traditional forms of data access, indexing, search and retrieval, which are either text-based or based on the query-by-example paradigm.
Thus, a video summary is a short version of an entire video sequence. The video summary can be represented into two fashions: a static video storyboard and a dynamic video skimming. Dynamic video skimming consists in selecting the most relevant small dynamic portions of audio and video in order to generate the video summary. On the other hand, static video storyboard is interested in selecting the most relevant frames (key frames) of a video sequence and generate the correspondent video summary.
In order to generate a correct and complete summarization of a given video, the employed model would have to per-form an optimal understanding of the video semantic content.
