Computational photography is an emerging research area that aims to extend or enhance the capabilities of digital photography by adding computational elements to the imaging process. Mobile phones have recently been gaining attention as a computing platform, due to advances in processing power and interactive displays, as well as enhanced programmability. Modern mobile devices are also equipped with good digital cameras. Their optical quality, resolution and photographic features have been quickly improving in recent years, making mobile phones a promising platform for computational photography.
The mobile scenario provides a unique and interesting platform for research and development in computational photography. Elements such as wireless network connectivity, high-resolution touchscreen, dedicated graphics processors, and presence of sensors such as accelerometers and magnetometers enable exciting applications. On the other hand, photography in this scenario poses additional challenges due to limitations of the photographic hardware when compared to high-end cameras, as well as the fact that photos are usually taken from a hand-held device, without resorting to the use of a tripod. Furthermore, traditional computational photography techniques can be computationally expensive, but in the mobile scenario it is often desired to immediately preview the capture result instead of saving the images for later off-line processing in a powerful computer. This motivates research on algorithms that make efficient use of the constrained computing resources to quickly preview the results, enabling users to recompose and recapture their photographs if desired while they are still present at the scene.
We are investigating novel techniques to address the challenges and to explore the possibilities of the mobile photography scenario. In particular, we are interested in:
