A 3D garment design and simulation system
(Bilkent University, 2004)In this thesis study, a 3D graphics environment for virtual garment design and simulation is presented. The proposed system enables the three dimensional construction of a garment from its two dimensional cloth panels, ... -
Animated mesh simplification based on saliency metrics
(Bilkent University, 2008)Mesh saliency identifies the visually important parts of a mesh. Mesh simplification algorithms using mesh saliency as simplification criterion preserve the salient features of a static 3D model. In this thesis, we propose ... -
Animation of human motion with inverse kinematics using nonlinear programming
(Bilkent University, 2001)Animation of articulated figures has always been an interesting subject of computer graphics due to a wide range of applications, like military, ergonomic design etc. An articulated figure is usually modelled as a set ... -
Automatic detection of salient objects for a video database system
(Bilkent University, 2005)Recently, the increase in the amount of multimedia data has unleashed the development of storage techniques. Multimedia databases is one of the most popular of these techniques because of its scalability and ability to ... -
Automatic determination of navigable areas, pedestrian detection, and augmentation of virtual agents in real crowd videos
(Bilkent University, 2018-12)Crowd simulations imitate the behavior of crowds and individual agents in the crowd with personality and appearance, which determines the overall model of a multi-agent system. In such studies, the models are often ... -
BilVideo-7 : video parsing, indexing and retrieval
(Bilkent University, 2010)Video indexing and retrieval aims to provide fast, natural and intuitive access to large video collections. This is getting more and more important as the amount of video data increases at a stunning rate. This thesis ... -
Bounding volume hierarchy-tetrahedralization hybrid acceleration structure for ray tracing
(Bilkent University, 2020-12)The computational cost of the ray-tracing method is directly proportional to the number of ray-surface intersection tests. The naive ray-tracing algorithm requires O(N) computational cost for the ray-surface intersection ... -
Communication models for crowd simulation
(Bilkent University, 2017-07)Modeling and animation of behaviorally plausible virtual crowds are important problems of crowd simulation research. We propose a communication model in order to equip virtual agents with the ability to autonomously ... -
A content-based image retrieval system for texture and color queries
(Bilkent University, 2002)In recent years, very large collections of images and videos have grown rapidly. In parallel with this growth, content-based retrieval and querying the indexed collections are required to access visual information. Two ... -
Conversational agent expressing ocean personality and emotions using laban movement analysis and nonverbal communication cues
(Bilkent University, 2019-08)Conversational human characters are heavily used in computer animation to convey various messages. Appearance, movement and voice of such characters in uence their perceived personality. Analyzing different channels of ... -
A disk-based graph database system with incremental storage layout optimization
(Bilkent University, 2016-01)The world has become ever more connected, where the data generated by people, software systems, and the physical world is more accessible than before and is much larger in volume, variety, and velocity. In many application ... -
Finding hidden hierarchy in social networks
(Bilkent University, 2016-06)Stratification among humans is a well studied concept that significantly impacts how social connections are shaped. Given that on-line social networks capture social connections among people, similar structure exist in ... -
From audiences to mobs : crowd simulation with psychological factors
(Bilkent University, 2010)Crowd simulation has a wide range of application areas such as biological and social modeling, military simulations, computer games and movies. Simulating the behavior of animated virtual crowds has been a challenging ... -
A hybrid hair model using three dimensional fuzzy textures
(Bilkent University, 2007)Human hair modeling and rendering have always been a challenging topic in computer graphics. The techniques for human hair modeling consist of explicit geometric models as well as volume density models. Recently, hybrid ... -
Learning from real-life experiences: a data-driven emotion contagion approach towards realistic virtual crowds
(Bilkent University, 2017-09)We propose a data-driven approach for tuning, validating and optimizing crowd simulations by learning parameters from real-life videos. We discuss the common traits of incidents and their video footages suitable for the ... -
Learning visual similarity for image retrieval with global descriptors and capsule networks
(Bilkent University, 2021-07)Finding matching images across large and unstructured datasets plays an im-portant role in many computer vision applications. With the emergence of deep learning-based solutions, various visual tasks such as image retrieval ... -
Mobile image search using multi-image queries
(Bilkent University, 2015-08)Visual search has evolved over the years, according to the demand of users. Single image query search systems are inadequate to represent a query object, because they are limited to a single view of the object. Therefore, ... -
Model-based camera tracking for augmented reality
(Bilkent University, 2014)Augmented reality (AR) is the enhancement of real scenes with virtual entities. It is used to enhance user experience and interaction in various ways. Educational applications, architectural visualizations, military ... -
Modeling and animating personalized faces
(Bilkent University, 2002)A very important and challenging problem in computer graphics is modeling and animation of individualized face models. In this thesis, we describe a facial modeling and animation system attempting to address this problem. ... -
Modeling and populating virtual cities: automatic production of building models and emergency crowd simulation
(Bilkent University, 2008)In this thesis, we present an automatic building generation method based on procedural modeling approach, and a crowd animation system that simulates a crowd of pedestrians inside a city. While modeling the buildings, ...
