New scheme to aid image search featured on Phys.org news site

Online databases now contain huge numbers of images. However there is only limited ability to search within these databases for an image with particular characteristics. Systems may rely on images being annotated with meaningful descriptions - "metadata".

Peter Wonka (of King Abdullah University of Science and Technology (KAUST) and Paul Guerrero and Niloy Mitra (both from University College London) wanted to add something more powerful to the currently limited repertoire of image search tools without adding extra metadata to existing images. They devised a query tool they call a relation-aug... [more]

Computer-Aided Verification award for Peter O'Hearn

Can a computer copy your handwriting?

Researchers at UCL Computer Science have taught a computer to imitate anyone's handwriting. They have created an algorithm that can take a sample of handwritten text, examine its qualities, and then write any text in the same style.

There are already typefaces in word processing programs that produce text in a fairly uniform handwritten style. But what Research Associate Tom Haines, member of UCL'S Intelligent Systems Research Group, and colleagues have done is create software that they claim reproduces the messy details of any individual writer's hand.

They call their system My Text In Your ... [more]

Battery status used to track people online

Lukasz Olejnik, Research Associate at UCL Computer Science, has contributed to a debate on how battery status indicators might be used to track devices, leading to privacy exposure.

Security researchers from Princeton University have shown that the battery status indicator really is being used in the wild to track user, a year after a privacy warning was issued. By running a specially modified browser, Princeton's Steve Engelhard and Arvind Narayanan found two tracking scripts that used the API to “fingerprint” a specific device, allowing them to continuously identify it across multiple contex...

Computer Science Spinout is a winner at UCL Business' Annual Summer Reception

A data science spinout from UCL Computer Science has received the UCLB One-to-Watch award 2016. Co-founded by the Department's Dr Jun Wang, Reader of Information Systems, MediaGamma has built an Audience Decision Engine, where the “Audience” are viewers of online ads.

The Decision Engine uses Machine Learning to provide information to digital ad trading platforms about the expected behaviour of a person potentially about to view that ad. This helps to inform the real-time decision-making process of the bidding algorithm as to whether or not to show a particular ad to a particular person.

The c... [more]

UCL Engineering's response to the EU Referendum Result

A message from The Provost

The outcome of the referendum is now known. While UCL did not take a formal position during the referendum campaign, I have given my personal view and you will have heard many other voices from the UCL community. The loss of EU membership will have a clear impact on universities such as UCL, particularly around the mobility of students and funding of research.

Today, more than ever, I want to reaffirm that UCL remains a global university through our outlook, people and enduring international partnerships. I also want in particular to address UCL’s staff and students... [more]
