In this article, we present a comprehensive measurement system to determine the level of user emotional arousal by the analysis of electrodermal activity (EDA). A number of EDA measurements were collected, while emotions were elicited using specially selected movie sequences. Data collected from 16 participants of the experiment, in conjunction with those from personal questionnaires, were used to...
The aim of this paper is to investigate the use of oculography signals for the recognition of experts in visual arts. We focused our attention on the number of sight transitions between characteristic image areas (ROIs). In the experiments we used oculographic data recorded at the Department of Experimental Psychology at the Catholic University of Lublin for 29 images and 34 users. The EM method was...
The article presents the use of genetic algorithm (GA) to select and classify ERD/ERS patterns. One hundred twenty eight channel EEG signal was used in the experiments. The signal was recorded for 40 people, during the process of imagining right and left hand movements. Feature extraction was performed using frequency analysis (FFT) with the resolution of 1Hz. So the features were spectral lines associated...
W artykule zaprezentowany jest algorytm automatycznej detekcji twarzy w obrazie statycznym. Detektor ma osiągać najwyższą skuteczność przy znajdowaniu twarzy możliwie niepochylonych i patrzących na wprost kamery. Wielkość wykrywanych twarzy musi być (z pewnymi odchyleniami) zgodna z rozmiarem twarzy zawartych na obrazach zastosowanych do uczenia klasyfikatora. Obrazy wejściowe mogą być kolorowe lub...
This paper discusses an asynchronous system of brain-computer interface, operating in real time. In the proposed system, the processing, analysis and classification of EEG signal is implemented using the Matlab programming environment and the BCI2000 package.
