Early wheat yield estimation at field-level by photosynthetic pigment unmixing using Landsat 8 image series
Ozcan, Aysenur; Leloğlu, Uğur Murat; Süzen, Mehmet Lütfi (2021-03-01)
This paper presents a novel approach for estimating wheat yields based on estimated abundances of endmembers attributed to photosynthetic pigments, using Landsat 8 images acquired during maximum greenness. Endmembers withi...
Species level classification of Mediterranean sparse forests-maquis formations using Sentinel-2 imagery
Caglayan, Semiha Demirbas; Leloğlu, Uğur Murat; Ginzler, Christian; Psomas, Achilleas; Zeydanlı, Uğur Siyami; Bilgin, Cemal Can; Waser, Lars T. (2020-07-01)
Essential forest ecosystem services can be assessed by better understanding the diversity of vegetation, specifically those of Mediterranean region. A species level classification of maquis would be useful in understanding...
A Method to Enhance Homogeneous Distribution of Matched Features for Image Matching
Gülmez, Baran; Demirtaş, Fatih; Leloğlu, Uğur Murat; Yaman, Mustafa; Güneyi, Eylem Tuğçe (2019-12-01)
Features are distinctive landmarks of an image. There are various feature detection and description algorithms. Many computer vision algorithms require matching of features from two images. Large number of correct matches ...
A fast and automated hydrologic calibration tool for SWAT
ÖZDEMİR, AYFER; Leloğlu, Uğur Murat (2019-11-01)
In order to apply hydrological models in the water resources investigation successfully, careful calibration and uncertainty analysis are required. Although many automatic calibration methods were developed, the time consu...
BoVSG: bag of visual SubGraphs for remote sensing scene classification
Amiri, Khitem; Farah, Mohamed; Leloğlu, Uğur Murat (2019-10-27)
Remote sensing scene classification is gaining much more interest in the recent few years for many strategic fields such as security, land cover and land use monitoring. Several methods have been proposed in the literature...
Robust landmine detection from thermal image time series using Hough transform and rotationally invariant features
Kaya, Serkan; Leloğlu, Uğur Murat; Ozyer, Gulsah Tumuklu (2019-07-28)
Automated detection of buried anti-personnel landmines using remote sensing techniques is very important for clearing minefields without putting lives in danger. Although thermal infrared imaging is promising, it is far fr...
