Building Extraction from High Resolution Satellite Images Using Hough Transform
(Copernicus Gesellschaft Mbh, 2010)
An approach was developed for the automatic extraction of the rectangular and circular shaped buildings from high resolution satellite imagery using Hough transform. First, the candidate building patches are detected from ...
Automatic Segmentation Of Colon Glands Using Object-Graphs
(Elsevier Science Bv, 2010)
Gland segmentation is an important step to automate the analysis of biopsies that contain glandular structures. However, this remains a challenging problem as the variation in staining, fixation, and sectioning procedures ...
Building Detection From Pan-Sharpened Ikonos Imagery Through Support Vector Machines Classification
(Copernicus Gesellschaft Mbh, 2010)
An approach is presented for detecting the buildings from high resolution pan-sharpened IKONOS imagery through binary Support Vector Machines (SVM) classification. In addition to original spectral bands, the bands nDSM ...
Defining Dynamic Spatio-Temporal Neighbourhood Of Network Data
(Copernicus Gesellschaft Mbh, 2010)
To improve the accuracy and efficiency of space-time analysis, spatio-temporal neighbourhoods (STNs) should be investigated and analysed in the classification, prediction and outlier detection of space-time data. So far ...
Road and Roadside Feature Extraction Using Imagery and Lidar Data For Transportation Operation
(Copernicus Gesellschaft Mbh, 2015)
Transportation agencies require up-to-date, reliable, and feasibly acquired information on road geometry and features within proximity to the roads as input for evaluating and prioritizing new or improvement road projects. ...
How Travel Demand Affects Detection Of Non-Recurrent Traffic Congestion On Urban Road Networks
(Copernicus Gesellschaft Mbh, 2016)
Occurrence of non-recurrent traffic congestion hinders the economic activity of a city, as travellers could miss appointments or be late for work or important meetings. Similarly, for shippers, unexpected delays may disrupt ...
Radiometric and Geometric Accuracy Analysis of Rasat Pan Imagery
(Copernicus Gesellschaft Mbh, 2016)
RASAT is the second Turkish Earth Observation satellite which was launched in 2011. It operates with pushbroom principle and acquires panchromatic and MS images with 7.5 m and 15 m resolutions, respectively. The swath width ...
