In recent years, especially in metropolitan cities such as Istanbul, the emerging needs of the increasing population and demand for better air transportation capacity have led to big environmental cha...
In modern traffic management Video Image Detection Systems (VIDS) are becoming increasingly important as traffic sensors. They are getting more affordable and don’t require any road construction like ...
Unpaved roads are one of the most relevant causes of erosion process in rural regions. Locating unpaved roads in low-resolution satellite images is not a trivial task. Although they have the spectra...
The collapsed buildings due to Izmit, Turkey earthquake that occurred on 17 August 1999 were detected from post-event aerial photographs using the shadow analysis and the perceptual grouping procedu...
With the growing use of digital map data, the requirements for frequent and efficient revision of digital map databases is equally growing. Revision of map databases can be divided into 3 steps...
This paper describes an algorithm which aims at deriving digital terrain models (DTM) from dense digital elevation models (DEM). This algorithm takes place in a processing chain for building detectio...
An automatic tie-point (TP) detection algorithm for multi-image triangulation and registration is described. The algorithm uses a hierarchical approach that leads from the initial extraction of local ...
Laser scanner data is being increasingly used to obtain topographical and object height information for mapping and GIS tasks. Valuable information can be derived of the terrain and objects of a reg...
This paper is concerned with the detection and separation of textures or stochastic information within an image. The texture is described mathematical by their stochastic. Because different kinds of ...
The paper describes a novel approach for the generation of 3D building models from airborne laserscanner data, which is based on the detection of straight lines in specific 2D projections of the dat...
