Dr Jonathon Hare from the University’s School of Electronics & Computer Science (ECS) will deliver a presentation entitled MapSnapper: engineering an efficient algorithm for matching images of maps from mobile phones, at the Electronic Imaging conference which will take place in San Jose, California, USA from 27-31 January.
Dr Hare, who carried out this research in conjunction with Professor Paul Lewis at ECS, will describe how he and his team developed MapSnapper, a robust algorithm to enable mobile phone users to take a photograph of a section of a map with a camera phone and have returned to them a high quality photograph of the section with points of interest added which the user can investigate further by clicking on them.
‘The vision was a product that would allow users to query a remote information system based on photos of a paper map taken with a camera phone,’ said Dr Hare. ‘The information system could then return useful information to the user via the device. For example, the returned information could include such things as events, facilities, opening times and accommodation in the selected geographical area.’
Dr Hare will describe how the algorithm combines a number of computer vision techniques, including interest point extraction and local description generator with multidimensional indexing. The outcome of this research is a fast robust algorithm which enhances the quality of mobile digital technology.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
