Research
Visual measurements and other applications of computer vision
Visual measurements of conventional and non-conventional features are now widely used in a range of application areas. Features like size, area and volume are considered conventional, while appearance (of a fabric), smoothness, roughness (of a tissue) are examples of less conventional features. The application areas for visual measurements include engineering, manufacturing, quality control, remote sensing and medicine, just to mention a few.
In medicine, for instance, new imaging devices and measurement tools appear regularly and these new devices and techniques provide ample opportunities to detect, measure, classify, and describe various spatial, temporal relationships between objects, tissues, cells. In many cases, new algorithms must be developed to explore these relationships. In other cases, tuning of existing algorithms can be satisfactory.
The applications often require that measurements relying on a number of 2D images produce relevant results in higher dimensional spaces. This increase in dimensions often poses questions on appropriate sampling rate and mode, on existing or possible correspondences, on estimation of precision and methods of calibration.
Development projects
Led the development of a vision-based measurement system – taking measurements in the visible and the NIR light spectra – for quantifying the lean content of minced meat (1990-1992, sponsored by the Hungarian State Council for Scientific Research).
Led a research project aiming at developing and evaluating image segmentation and image description methods to be used in vision-based measurement systems for biological objects. (1992-1995, sponsored by the Hungarian State Council for Scientific Research).
In cooperation with colleagues from the Department of Ophthalmology, Semmelweis Medical School, carried out research on the automatic evaluation of ophthalmological images (1994-1997, sponsored by the Hungarian State Council for Scientific Research.
Led a research project on automatic structural evaluation of fabrics based on their visual appearance. In cooperation with the textile-experts of the Innovatext Textile Engineering and Testing Laboratory Coordinating the (1996-1997 PHARE-TDQM project sponsored by the EU.)
Took part in the project – run by the consortium of Computer and Automation Research Institute, Eötvös Loránd University, Contware Research and Development Ltd. and Semmelweis University – aiming at developing a multi-camera cornea topographerfor ophthalmologic practice and corresponding measurement methods (2005-2007 NKFP-2/020/04).
