Rao-Blackwell parçacık süzgeci ile 3 boyutlu insan takibi
Topçu, O.; Orguner, U.; Alatan, A. A.; Ercan, Ali Özer (IEEE, 2014)Visual tracking has an important place among computer vision applications. Visual tracking with particle filters is a well-known methodology. The performance of particle filters is dependent on efficient sampling of the ... -
Recovery of temporal synchronization error through online 3D tracking with two cameras
Topçu, O.; Ercan, Ali Özer; Alatan, A. A. (ACM, 2014)Multiple object tracking within a network of cameras with overlapping fields of views has gained interest. The acquisition of images in an asynchronous manner hinders the practical implementation of such systems. Most of ... -
Rf energy harvesting and transfer for spectrum sharing cellular iot communications in 5g systems
Ercan, Ali Özer; Sunay, M. O.; Akyildiz, I. F. (IEEE, 2018-07-01)This paper proposes an energy and spectrum efficient IoT network for 5G systems where spectrum is shared with the cellular system for spectrum efficiency and energy harvesting and energy transfer are utilized for energy ... -
A software-defined networking approach for wireless systems
Yazıcı, Volkan (2015-05)The tremendous growth in wireless Internet use is showing no signs of slowing down. Existing cellular networks are starting to be insufficient in meeting this demand in part due to their inflexible and expensive equipment ... -
A stereo HMD system with visual and inertial data capture for 3D augmented reality applications
Kermen, Ahmet (2016-01)Augmented Reality (AR) technology has been considered to have a great potential in many different areas such as medical visualization, manufacturing, entertainment and cultural heritage for enhancing human-computer interaction ... -
Successive refinement of models for model-based testing to increase system test effectiveness
Sahin Gebizli, C.; Sözer, Hasan; Ercan, Ali Özer (IEEE, 2016)Model-based testing is used for automatically generating test cases based on models of the system under test. The effectiveness of tests depends on the contents of these models. Therefore, we introduce a novel three-step ...
