Motion compensated three dimensional wavelet transform based video compression and coding
Biçer, Aydın; Ünver, Baki Zafer; Department of Electrical and Electronics Engineering (2005)
In this thesis, a low bit rate video coding system based on three-dimensional (3-D) wavelet coding is studied. In addition to the initial motivation to make use of the motion compensated wavelet based coding schemes, the other techniques that do not utilize the motion compensation in their coding procedures have also been considered on equal footing. The 3-D wavelet transform (WT) algorithm is based on the أgroup of framesؤ (GOF) concept. The group of eight frames are decomposed both temporally and spatiall...
Human activity recognition by Gait Analysis
Kepenekci, Burcu; Akar, Gözde; Department of Electrical and Electronics Engineering (2011)
This thesis analyzes the human action recognition problem. Human actions are modeled as a time evolving temporal texture. Gabor filters, which are proved to be a robust 2D texture representation tool by detecting spatial points with high variation, is extended to 3D domain to capture motion texture features. A well known filtering algorithm and a recent unsupervised clustering algorithm, the Genetic Chromodynamics, are combined to select salient spatio-temporal features of the temporal texture and to segmen...
A virtual human animation tool using motion capture data
Nar, Selim; Çetin, Yasemin; Department of Medical Informatics (2008)
In this study, we developed an animation tool to animate 3D virtual characters. The tool offers facilities to integrate motion capture data with a 3D character mesh and animate the mesh by using Skeleton Subsurface Deformation and Dual Quaternion Skinning Methods. It is a compact tool, so it is possible to distribute, install and use the tool with ease. This tool can be used to illustrate medical kinematic gait data for educational purposes. For validation, we obtained medical motion capture data from two s...
Improving the sight efficiency of visually impaired people with games that can be played with motion capture systems
Konya, Oğuz; Çağıltay, Kürşat; Department of Game Technologies (2014)
This thesis researches whether the life skills and eye-body coordination of the visually impaired children can be improved through the use of video games which use motion capture system as input. It also researches what kind of video games can be developed and how they can be used in order to provide benefit to visually impaired children. This study was conducted as a mix of qualitative and quantitative studies. It was carried out in six phases. In the first phase, the psychomotor development areas of the v...
High-density and homogeneous mapping using a motion controlled lidar
Canbolat, İsmail Melih; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2023-1-25)
LiDAR is a commonly used method for mapping and obstacle detection in various robotics applications. With the advancement of technology, 3D scanning LiDAR sensors became widely available. Most 3D scanning LiDAR sensors have a 360° horizontal field of view, but they have a limited vertical field of view which is determined by the desired vertical scanning resolution and the number of laser scan layers. Limited number of horizontal layers in a LiDAR sensor introduces large gaps in the obtained point cloud map...
