A NOVEL BOVW MIMICKING END-TO-END TRAINABLE CNN CLASSIFICATION FRAMEWORK USING OPTIMAL TRANSPORT THEORY
Gürbüz, Yeti Ziya; Alatan, A. Aydin (2019-01-01)
An end-to-end trainable convolutional neural network (CNN) framework which mimics bag of visual words (BoVW) is proposed for image classification. To this end, a new paradigm for histogram-like image representation is intr...
Roadesic Distance: Flow-Aware Tracklet Association Cost for Wide Area Surveillance
Gürbüz, Yeti Ziya; CAN, OĞUL; Alatan, Abdullah Aydın (2017-09-20)
Long-term multi-target tracking via tracklet merging in wide area surveillance has crucial importance to improve tracker performances and operational requirements. Min-cost network flow formulation for multi-target trackin...
Association Cost Enforcing Spatial Consistency for Tracklet Merging
Gürbüz, Yeti Ziya; Can, Ogul; Alatan, Abdullah Aydın (2017-05-18)
In this study, min-cost network flow formulation for multi-target tracking is adopted for the tracklet merging problem in wide area surveillance. In order to improve the continuity of the computed flows by the min-cost net...
AUTOMATIC ROAD DETECTION FROM GRAY LEVEL IMAGES IN WIDE AREA SURVEILLANCE
OĞUL, Can; Gürbüz, Yeti Ziya; Alatan, Abdullah Aydın (2016-07-17)
Wide Area Surveillance (WAS) systems are capable of providing continuous surveillance of critical areas as wide as city center (approximately 20 km square), mostly as a gray-level video. Utilization of road information for...
Sparse recursive filtering for O 1 stereo matching
Gürbüz, Yeti Ziya; Çığla, Cevahir; Alatan, Abdullah Aydın (2015-09-30)
Recursive edge-aware filters have been proved to be one of the most efficient approaches for cost aggregation in stereo matching. However, disparity search space dependency, as a result of full search, is the bottle-neck o...
Sparse Recursive Cost Aggregation Towards O(1) Complexity Local Stereo Matching
Gürbüz, Yeti Ziya; Alatan, Abdullah Aydın; Cigla, Cevahir (2015-05-19)
The complexity of the local stereo matching methods mainly increases with disparity search range and cost aggregation step. Joint elimination of the those complexity factors is a challenging task as a consequence of the co...
Inshore Ship Detection in Multispectral Satellite Images
Besbinar, Beril; Gürbüz, Yeti Ziya; Alatan, Abdullah Aydın (2015-05-19)
In this paper, a novel method is proposed for the detection of sea and inshore ships in satellite images which contain red, green, blue and near-infrared bands. For sea detection, an initial mask is obtained by thresholdin...
Tubularity Tracking Based Automatic Road Detection from Sattelite Images
Gürbüz, Yeti Ziya; Alatan, Abdullah Aydın (2014-04-25)
In this paper, a novel approach based on tubularity tracking and graph cuts for road detection from satellites images is presented. The most important feature of the proposed method is its local peak detection filter. Unli...
Region of Interest Detection Based Fast and Robust Geo-Spatial Object Recognition
Gürbüz, Yeti Ziya; Alatan, Abdullah Aydın (2013-01-01)
In this paper a novel computationally efficient algorithm to detect objects automatically from high definition satellite imagery with high performance is presented. The proposed algorithm has three main steps supporting ea...
Video Mosaicing of Planer Scenes using Extended Kalman Filter
Bati, Emrecan; Gürbüz, Yeti Ziya; Alatan, Abdullah Aydın (2013-01-01)
In this work, the large planar scene is reconstructed from small images. Small images can be consecutive video frames or sequence of photographs. In the problem, called mosaicing, instead of using widely used optimization ...
