Research work at the Faculty focuses mainly on the interdisciplinary area between life sciences, computer science and engineering, and on strengthening the convergence paradigm of these fields. The flat departmental organization of the Faculty makes cooperation between different research groups particularly easy.
The Faculty's capacities in computing and dedicated hardware architecture design are also outstanding, which in particular helps solve complex computational problems that arise in engineering design or biological data analysis.
Research and education are closely linked at the Faculty, which was awarded the title of 'Research University Faculty' by the Hungarian Government in 2013. This title was only given to 4 faculties out of 115 in Hungary.
Students actively take part in research during their university years. They can work individually or in teams on a chosen topic with the assistance of a researcher or professor within the framework of the Research Experiences for Undergraduates Program, and later join one of 22 research groups of the Jedlik Laboratories.
Jedlik Laboratories is the center of scientific activity at the Faculty, where professors and researchers are joined by PhD and Master students. Study and innovation are linked through major research laboratories and state-of-the-art SMEs, from both Hungary and abroad. Jedlik Laborator was established with partners like the Semmelweis Medical University, major start-up companies, and five research institutes of the Hungarian Academy of Sciences:
Institute for Computer Science and Control,
Institute of Experimental Medicine,
Institute of Enzymology,
Institute of Technical Physics and Materials Science,
Institute of Cognitive Neuroscience and Psychology.
Biology inspired and Neuromorphic models sensing and algorithms
We have worked and achieved important results in almost all segments of sensing together with the collaborating neurobiology research teams including international partners. The majority of models are neuromorphic, which is important because the topographic sensors can be easily implemented on their cellular topographic microprocessors.
The retinotopical part of visual perception, furthermore its link to the most innovative neurobiological research outcomes (Berkeley, Harvard) needs to be emphasized from the results.
The most important results in the field of visual perception are in connection with the CNN modeled multi channel functioning of the retina. The simulation of the multi layered CNN models very well reflected the neurobiological measure results of the original paper. Based upon these it was possible to find a model for saccadic interruption. These models served as a basis for other later presented results.
The study of the effects of amblyophia, the problem analysis of its early diagnosis and the solutions.
In cochlear modeling a few effects were modeled successfully. This theoretical model was applied in the development of our special preprocessing unit for multi-channel cochlear implants. Vowels can be recognized using Hough-transform on the output signal of the implants. We also developed an estimation algorithm for the direction of auditory events, that can extract useful information from the background noise.
Understanding the four channel model of the tactile perception we model the basic tactile situations with receptive field combinations. We classify the tactile event spaces with the implementing MEMS.
Studying the role of the flexible skin, we managed to find a solution to the inverse problem of flexible or elastic cover (i.e. to reconstruct the original pressure force from the force components measured in the discrete points).
Multimodal sensing, fusion and navigation
We conducted experiments concerning the fusion of multispectral visual perception and worked out algorithms. We manage to detect effects that can not be seen neither in daylight nor at night with the synthesis of the two visual spectrums.
In crossmodal cortical experiments in case of visual and somatosensory modalities we managed to demonstrate new effects in rats and humans including the results of left handedness.
We started to study the experimental electronic leg actuation of spinal chord injury patients and the analyses of experimental methods of actuation analysis.
Attention, memory and plasticity
Using the multi channel retina model we managed to solve algorithmically the generation of the non-voluntary visual distinction attention map. By the end of 2005 we managed to work out a control methodology for its experimental verification. This is a human experiment.
Neuromorphic model library
After several years of research a Receptive Field Atlas was finished and published, which assigns CNN modeled receptive field organizations to several functions mostly in the field of visual perception.
Immune response inspired models and algorithms
Studying the immune response we managed to give an algorithmic frame to a spatiotemporal artificial immune response mechanism (see its application later).
In electronic and photonic applications we studied what kind of circuits can be realized from nano-particles (can be molecules, or metal nanoparticles) that are attached by electromagnetic interactions. We analyzed how horizontal cell structures of molecules, nano-magnets and, good conductor metal nanoparticles (metal-dots, nanoantennae) can act as different parts of electronic circuits, i.e. what are the conditions and limitations of nanocircuits.
According to our findings which were conducted in cooperation with the University of Notre Dame Center for Nano Science and Technology (ND-CNST) there is no theoretical limitation of molecules joined with Coulomb force fulfill any digital system function.
We have shown that digital systems can be built from nanomagnets that are joined with magnetic field

Cellular wave computers and the basics of the connecting hardware software technology
The basics of cellular computers defined by image flows – complexity and spatiotemporal, analogue-binary-wave-logic
We have elaborated several algorithms in this period. We would mention the active contour detection, the layer-set based CNN algorithm the histogram equalizer, the optical flow computing and the locally adaptive sensoring tuning CNN algorithms.
These have been important results in the fields of the stability of multi layer wave computers. The analysis algorithmic capacities and limitations, the solutions to some difficult problems of physical systems described by partial differentiations and the generation of real spatiotemporal random image flows that clarified the theoretical foundations of cellular wave computers.
