New algorithm for digital map technology

25.01.2008
New technology to enhance digital map technology will be presented by a University of Southampton academic at a conference in California next week.

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.

Im Focus: Electrons in the fast lane

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.

Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....

Im Focus: The lightest electromagnetic shielding material in the world

Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.

Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

Im Focus: AI monitoring of laser welding processes - X-ray vision and eavesdropping ensure quality

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.

Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
