NASLOV: Harnessing Deep Neural Networks for Area of Interest Annotation in Eye Tracking Research
-----------------------------------------------------------------------------------------------------------------------------------------
POVZETEK:
Eye gaze is widely recognised as an important indicator for understanding and predicting user behaviour, as well as directing their attention across various domains including advertisement design, human-computer interaction and film viewing. We present a novel method to enhance the analysis of user behaviour and attention by (i) augmenting video streams with automatically annotated and labelled areas of interest (AOIs), and (ii) integrating AOIs with collected gaze and fixation data. The tool provides key features such as time to first fixation, dwell time, and frequency of AOI revisits. Using the capabilities of the YOLOv8 object tracking algorithm, the tools supports over 600 different object classes, providing a comprehensive set for a variety of video streams. This tool will be made available as open-source software, thereby contributing to broader research and development efforts in the field.

PREDAVATELJ: Milan MILIVOJČEVIĆ
------------------------------------------------
Milan Milivojčević is a second-year Computer Science master's student at UP FAMNIT. He previously obtained a Computer Science bachelor's degree at UP FAMNIT. He will be presenting the work that was done on his study exchange at the Charles University in Prague together with colleagues Todor Antić and Jelena Glišić. This work was published on the 40th European Workshop on Computational Geometry (EuroCG) and on the International Workshop on Combinatorial Algorithms (IWOCA) 2024.

NASLOV: Star-Forest Decompositions of Complete Graphs
-------------------------------------------------------------------------------
POVZETEK:
This work deals with the problem of decomposing a complete geometric graph into plane star-forests. In particular, we disprove a recent conjecture by Pach, Saghafian and Schnider by constructing for each n a complete geometric graph on n vertices which can be decomposed into ⌈n/2⌉ +1 plane star-forests. Additionally we prove that for even n, every decomposition of complete abstract graph on n vertices into n/2 +1 star-forests is composed of a perfect matching and n/2 star-forests with two edge-balanced components, which we call broken double stars.
