TL;DR: STIMO is a summarization technique designed to produce on-the-fly video storyboards that produces still and moving storyboards and allows advanced users customization and is based on a fast clustering algorithm that selects the most representative video contents using HSV frame color distribution.
Abstract: In the current Web scenario a video browsing tool that produces on-the-fly storyboards is more and more a need. Video summary techniques can be helpful but, due to their long processing time, they are usually unsuitable for on-the-fly usage. Therefore, it is common to produce storyboards in advance, penalizing users customization. The lack of customization is more and more critical, as users have different demands and might access the Web with several different networking and device technologies. In this paper we propose STIMO, a summarization technique designed to produce on-the-fly video storyboards. STIMO produces still and moving storyboards and allows advanced users customization (e.g., users can select the storyboard length and the maximum time they are willing to wait to get the storyboard). STIMO is based on a fast clustering algorithm that selects the most representative video contents using HSV frame color distribution. Experimental results show that STIMO produces storyboards with good quality and in a time that makes on-the-fly usage possible.

TL;DR: It is believed that it is necessary to redesign the utilization paradigm of Web 2.0 and, in general, of the Internet in order to recycle unused parts of Web2.0 into altruistic bricks that could be appropriately rerouted and composed for alternative, unselfish employment.
Abstract: Web 2.0 is affecting the structure of our society by creating new spaces of freedom, giving voice to any opinion, easing interpersonal relationships, and encouraging the creation of collaborating collectivities. Technologies such as blog, podcasting, wiki, and news feeds have the power to transform every user from a mere information consumer to a potential producer, from a spectator to an actor. The success of YouTube, MySpace, Facebook, and Wikipedia is under everybody's eyes. Generally speaking, Web 2.0 is seen as a powerful tool that, by exploiting Internet technologies, supplies services to the society, helping the entire socio-cultural system to develop and to move toward a democratic direction. Unfortunately, this imagery is partially distorted: first, Web 2.0 and Internet technologies are differently accessible by different parts of the society and, second, as many sociologists pointed out, their applications often appeal to users' egoistic purposes and self-celebration spirit. Although we cannot dismiss the value of current Web 2.0 applications, we are convinced there is a much more valuable potential that has not been exploited yet. By comparing the immense benefits that Web 2.0 could bring to the whole society, with its factual employment, one could provocatively change the meaning of the acronym WWW into World Wide Waste. We are hence convinced that it is necessary to redesign the utilization paradigm of Web 2.0 and, in general, of the Internet in order to recycle unused parts of Web 2.0 into altruistic bricks that could be appropriately rerouted and composed for alternative, unselfish employment.
