Project Summary
The COSIS project (financed by FCT, MCES, Lisbon, Portugal: POCTI-CTE-AST/58333/2004) purpose is to develop a software tool for automatic image processing and feature recognition of sunspots (K1), chromospheric plages (K3), and filaments (Ha) for usage by astronomers and other interested parties.The long-term objective is to create a data center (Solar/Astronomical Data Center of the OAUC – under consideration) and to integrate this data center in the Virtual Observatory project. In 2006 a CCD camera was installed at the spectroheliograph of the OAUC in collaboration with Dr. M. Klvana and Dr. V. Bumba from the Astronomical Institute, Czech Academy of Sciences, Ondrejov, Czech Republic. The camera allowed simultaneous test observations by CCD camera and regular patrol observations to a planfilm and since March 2007 only directly digitized observations of the Sun are performed regularly. In collaboration with Dr. M. Klvana and Dr. V. Bumba from the Astronomical Institute, Czech Academy of Sciences, Ondrejov, Czech Republic it is foreseen to install in 2005 a CCD camera at the spectroheliograph of the OAUC to perform directly digitized observations of the Sun. All this process would enable to make available daily images at the website of the OAUC (Solar Datacenter of the OAUC – under consideration).
Research Areas We put together a team of specialists from different areas of knowledge: astronomy/solar physics, decision support systems and image recognition. The assembled team includes researchers from UNINOVA and Coimbra Astronomical Observatory. We believe that these different areas of expertise will create a synergy between the researchers involved towards achieving a useful tool that could be used worldwide.The COSIS prototype to be developed integrates several computing key technologies:
- Decision support oriented database
- Image/feature recognition techniques
Expected Results The overall expected result for this project is to create a datacenter in the Coimbra Astronomical observatory, for storage and manipulation of solar data, extracted from the rich heritage of existing images;The expected results are: - To maximize the scientific return of the Coimbra heritage on solar data images.
- To extend the scientific knowledge and experience with Image recognition processes at UNINOVA.
- To improve the visibility of the research done at UNINOVA and Coimbra Observatory by publishing the project related results.
