Object tracking in the presence of occlusions using multiple cameras: a sensor network approach
Ercan, Ali Özer; El Gamal, A.; Guibas, L. J. ( Association for Computing Machinery, 2013)This article describes a sensor network approach to tracking a single object in the presence of static and moving occluders using a network of cameras. To conserve communication bandwidth and energy, we combine a task-driven ... -
Occlusion-aware 3D multiple object tracker with two cameras for visual surveillance
Topçu, O.; Alatan, A. A.; Ercan, Ali Özer (IEEE, 2014)An occlusion-aware multiple deformable object tracker for visual surveillance from two cameras is presented. Each object is tracked by a separate particle filter tracker, which is initiated upon detection of a new person ... -
On sensor fusion for head tracking in augmented reality applications
Ercan, Ali Özer; Erdem, Tanju (IEEE, 2011)The paper presents a simple setup consisting of a camera and an accelerometer located on a head mounted display, and investigates the performance of head tracking for augmented reality applications using this setup. The ... -
On the feasibility of synchronous, retransmission-based cognitive networks
Ercan, Ali Özer; Sunay, Mehmet Oğuz (Elsevier, 2016-01)This paper presents a new, joint Markov chain model for the primary and secondary traffic in a cognitive radio network to assess the feasibility of opportunistic spectrum access for different operational scenarios, validated ... -

Bakır, M.; Aydoğan, B.; Aydın, M.; Khodabakhsh, Athar; Arı, İsmail; Ercan, Ali Özer (IEEE, 2014)Rafineriler tonlarca ham petrolün, her gün faklı kimyasal işlemden geçirilerek benzine ve diğer yan ürünlere dönüştürüldüğü dev endüstriyel tesislerdir. Bu makalede sensör-tabanlı petrol rafinelerine özel endüstriyel büyük ... -
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 ... -
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 ...
