An approximation algorithm for computing the visibility region of a point on a terrain and visibility testing
(IEEE, 2014-01)Given a terrain and a query point p on or above it, we want to count the number of triangles of terrain that are visible from p. We present an approximation algorithm to solve this problem. We implement the algorithm and ... -
Cortical processes underlying attentional modulations of dynamic vision
(Bilkent University, 2022-09)Visual attention is one of the most fundamental cognitive functions guiding and influencing a various number of processes. However, how different neural mechanisms are modulated by selective attention to process information ... -
Emergency crowd simulation for outdoor environments
(Pergamon Press, 2010)We simulate virtual crowds in emergency situations caused by an incident, such as a fire, an explosion, or a terrorist attack. We use a continuum dynamics-based approach to simulate the escaping crowd, which produces more ... -
Extraction of 3D navigation space in virtual urban environments
(IEEE, 2005-09)Urban scenes are one class of complex geometrical environments in computer graphics. In order to develop navigation systems for urban sceneries, extraction and cellulization of navigation space is one of the most commonly ... -
“Night Hawks” watching over the city: redeployment of night watchmen and the politics of public space in Turkey
(Sage Publications, 2019-11)Technological advances have enormously increased surveillance techniques in the last three decades. In this article, we scrutinize the re-instatement of bekçi, the traditional night watchmen patrolling the residential ... -
Spatial attention and paracontrast masking
(Bilkent University, 2021-01)Visual masking is a powerful methodological tool to investigate the dynamics of sensory processing associated with object visibility and identity. Previous paracontrast masking studies revealed three distinct components ... -
A tool for pattern information extraction and defect quantification from crystal structures
(Elsevier, 2015)In this paper, we present a revised version of BilKristal 2.0 tool. We added defect quantification functionality to assess crystalline defects. We improved visualization capabilities by adding transparency support and ... -
Visibility-based assessment of urban form: an alternative perspective for the residential development in urban peripheries
(Bilkent University, 2021-07)It is highly important for urban designers to understand how the configuration of urban fabric influences the living experience of the city dwellers. While cities change through time, their evolution may produce spaces ... -
Youtube vlogs, stardom and LGBTQ community
(Bilkent University, 2018-02)This thesis analyzes the rising importance of YouTube vlogs and vloggers against mainstream media organs in terms of self-representation and affiliation. The research specifically focuses on LGBTQ individuals’ sexual ...
