Funding for ReVision from Academy of Finland

The Academy of Finland decided to fund the project Re-Engineering Retinal Imaging with Photonics and Computational Science.

On June 8, the ReVision consortium received a positive funding decision. The consortium partners are the University of Eastern Finland (responsible institution; photonics) and the University of Tampere (ophthalmology). The project has strong international collaboration with the University of Birmingham and Tokyo Institute of Technology.

ReVision is a multidisciplinary research project focusing on improving retinal imaging, image processing, and computational analysis of the image data to enable efficient automatic and semi-automatic methods for eye health. Retinal imaging is commonly used in ophthalmology and digital retinal cameras are in wide use in the western health care, for example, for the screening of diabetic retinopathy and age-related macular degeneration. With the proposed research, the current clinical practices are challenged by claiming that through the adoption of spectral imaging techniques, it is possible to significantly improve the examination of the eye when compared to the existing photographic systems based on grey-level and RGB imaging. Spectral imaging can be the missing part in the development of accurate and reliable methods for automatic monitoring and screening.

The project will begin in September 2012. The principal investigator of LUT is Associate Prof. Lasse Lensu.

Award to the Ville Kangas's Master's thesis

The Finnish Society for Computer Science honorary mention to the Ville Kangas's Master's thesis

The Finnish Society for Computer Science (Tietojenkäsittelytieteen seura ry) awarded Ville Kangas's Master's thesis "Comparison of Local Feature Detectors and Descriptors for Visual Object Categorization" with honorary mention and grant. The thesis was supervised by Professor Joni-Kristian Kamarainen and researcher Jukka Lankinen and it introduced novel evaluation methodology for local feature detectors and descriptors.


Funding from Academy of Finland

Academy of Finland awarded a grant for project Symbol Grounding under Uncertain Measurements.

Academy of Finland awarded a grant for MVPR's project "Symbol Grounding under Uncertain Measurements". The project will study how to connect bottom-up signal processing and pattern recognition with high-level artificial intelligence and inference. The main problem is how to build intelligent systems which could learn new concepts based on their own experience, by grounding low-level signal phenomena to relevant higher level symbolic concepts, without requiring these symbols to be explicitly defined by a human. Service robots of the future will need the capability of acting in environments which are not known in advance. To plan and complete tasks in such an environment, inference on symbolic level is necessary. Thus, the symbol grounding capability is essential for the development of the future robot systems. The project will begin in January 2012. The principal investigator of the project is Prof. Ville Kyrki.


Funding for the PulpVision project

Research funding for visual inspection in pulping using machine vision was continued for two years by Tekes
