This paper presents an original approach to identify oil depots from single high resolution aerial/satellite images in an automated manner. The new approach considers the symmetric nature of circular oil depots, and it computes the radial symmetry in a unique way. An automated thresholding method to focus on circular regions and a new measure to verify circles are proposed. Experiments are perf...

Uzaktan algılama teknolojilerinin gelişmesi, farklı analiz yöntemleri ve yazılımlar sayesinde uydu görüntüleri üzerinden nesnelerin yüksek doğrulukla sınıflandırılmaları mümkündür.

With the introduction of new satellites for earth monitoring characterized by very high resolution (VHR) sensors, new algorithms to recognize shadow in the supplied images are necessary. Automatic shadow detection can enhance the interpretability of the images in several applications such as classification and change detection. Several approaches are present in literature for shadow detection a...

Kibo, the highest of three peaks of Kilimanjaro, has not benefited from a medium to large scape topographic mapping in about 50 years. The rapidly changing topography associated with the glacier retreat and the fact that the slopes of Kibo attract about 40,000 climbers each year thus justify the need to develop a new topographic survey of this outstanding landmark, designated a UNESCO World Her...
