Digitally remastered wire art to be showcased at SIGGRAPH 2017

A new image-based method captures the complexities of thin structures, providing an innovative technique to reconstruct wiry objects digitally - just from a few input images. The novel computational method is poised for wide reach, by animators to depict the behavior of any wire- or cable-like object or by the medical practitioners to examine networks of thin structures, like a network of blood vessels.

Developed by computer scientists at University of Hong Kong, Adobe Research and UCL, "Image-based Reconstruction of Wire Art," will be one of several innovative computer graphics and interactiv... [more]

UCL improves insights for surgeons

UCL Computer Science is exploring how Microsoft HoloLens can transform medical imaging, such as CT scans, into 3D models. Surgeons can then use these three-dimensional anatomical holograms to plan for complicated surgeries and to help patients get a clearer picture and better understanding of their own bodies.

A collaboration between University College London Hospitals NHS Foundation Trust, UCL Computer Science, and NHS Code4Health, under the Platform for Enhanced Analytics and Computational Healthcare (PEACH), is developing the technology to help surgeons understand the specific anatomy and c... [more]

Smart detectors to monitor urban bat life

The activity of urban bats in Queen Elizabeth Olympic Park in London is being monitored in real-time using new, automated smart detectors that have been developed and installed by UCL and Intel scientists in collaboration with Arup, the Bat Conservation Trust and the London Wildlife Trust.

Bats are a good indicator species, so are often used to measure how healthy our environment is. By detecting bat ultrasonic calls, the monitors will track species present and their activity levels and display the information to the public. This will provide an insight into the wildlife health of the Park ove... [more]

Bio-Inspired Robotics Summer School success

As part of the week-long celebrations for UK National Robotics Week, UCL Computer Science, led by Professor Steve Hailes and Dr Rae Harbird, hosted a Bio-Inspired Robotics Summer School.

Year 12 school students from local London schools had the opportunity to use their creativity and ingenuity to design and build robots that can jump, walk and slither. They were taught by world-leading experts in the field of robotics from academia and industry; and were encouraged to think about issues around functionality, autonomy, intelligence, control and structures of bio-inspired robots and experiment w...

Computer Science wins Zero Tolerance To Sexual Harassment Award

On Wednesday 14 June UCL Computer Science was presented with a Zero Tolerance To Sexual Harassment Award to celebrate the work of its staff and students over the past year in creating a Zero Tolerance environment at UCL.

Computer Science was named as one of thirty departments across UCL to have successfully implemented all elements of the Zero Tolerance Pledge, as part of a campaign run by UCLU.

The Department would like to thank JJ Giwa (photographed receiving the award) for arranging seminars and acting as the first point of contact, while incoming students have been trained to be Active Bys... [more]

Is the Internet of Things secure?

Steven Murdoch, Research Fellow in the Information Security Research Group at UCL Computer Science has been interviewed for The Naked Scientists, 'Is the Internet of Things secure?'.

The radio broadcast is available here (available until 3 July 2017); a transcript appears below between Steven and Timothy Revell:

A world is fast approaching where everything around us is connected to the Internet. Your fridge will shop online for more milk and ice-cream when you run low, your phone will tell your oven that you’re behind schedule on the journey home and to turn the dinner down, and the heating wi... [more]

UCL delivers first systematic study of the network effects shaping digital reputation in P2P platforms

Three researchers from UCL Computer Science, Giacomo Livan, Fabio Caccioli, and Tomaso Aste, have shown that the reputation systems that underpin online P2P platforms (such as Uber and AirBnB) can be made unreliable for all participants by some users’ tendency to exchange ratings. The findings are published in the 14th June issue of Nature Scientific Reports: “Excess reciprocity distorts reputation in online social networks”.

The current landscape of the online digital economy is largely organized as a “platform society” of users who exchange knowledge, goods, and resources on a peer-to-peer b... [more]

Shining a light on the dark corners of the web

Gianluca Stringhini, lecturer in UCL's Information Security group, is featured in a Nature feature: 'Shining a light on the dark corners of the web'. Gianluca was interviewed about the group's research around 4chan, fake news, online raids and hate speech.

As a cybercrime researcher Gianluca he has studied ransomware, online-dating scams and money laundering. In May, his team published two papers exploring how hate speech and fake news are spread around the Internet, focusing on the notorious but popular 4chan message boards.

In a conference-proceedings paper, the researchers analysed 8 millio... [more]

UCL 1st Workshop in Biological Computational Systems

The aim of this workshop is to bring together people and ideas that would not otherwise meet: leading scientists at the intersection of biology, chemistry, engineering and computer science; to discuss the potential of Biological Computational Systems.

Computation is an intrinsic attribute of biological systems: gathering and processing of information and respond to an external environment. Over the last century, several research fields have adopted the intuition and the analysis of living organisms as information processing systems.

The ability to read biological information at large-scale (i.... [more]
