We demonstrate an attentional selection and tracking system for processing video streams from remotely operated underwater vehicles (ROVs). The system identifies and tracks potentially interesting visual events spanning multiple frames based on low-level properties of salient objects, which are associated with those events. If video frames contain interesting frames, they are labeled “interesti...

We demonstrate an attentional selection system for processing video streams from remotely operated underwater vehicles (ROVs). The system identifies potentially interesting visual events spanning multiple frames based on low-level spatial properties of salient tokens, which are associated with those events and tracked over time. If video frames contain interesting frames, they are labeled “inte...

Graphical passwords are believed to be more secure than traditional textual passwords, but the authentications are usually complex and boring for users. Furthermore, most of the existing graphical password schemes are vulnerable to spyware and shoulder surfing. A novel graphical password scheme ColorLogin is proposed in this paper. ColorLogin is implemented in an interesting game way to weaken ...

The UK's Millennium Seed Bank, part of the Royal Botanic Gardens, Kew, has collected its billionth seed for safekeeping and conservation. The seed was presented to the British chancellor, Gordon Brown, ahead of an official ceremony at the Seed Bank in southern England late last month to mark World Biodiversity Day. The Millennium Seed Bank (MSB) Project is one of the most ambitious conservation...

The goal of more powerful computers is to enable more demanding applications. I will not venture to take a guess at what will be the dominant "killer applications" for billion transistor chips. Historically new applications have arisen as computers became more powerful; I expect the future to be no different. New applications will continue to demand more and more computing power. The problem of...
