FIELD OBSERVATION OF CORAL COASTS BY OBLIQUE AERIAL PHOTOGRAPHS

Oblique Aerial Photographs - an “old-new” Data Source

New imaging platforms, progress in digital cameras, the use of GNSS/IMU technology either in direct sensor orientation or in integrated sensor orientation, new thinking with regard to control information in georeferencing, and co-operation between two disciplines – photogrammetry and computer vision – have brought the possibility of using oblique aerial photographs as a data source into the lim...

Identifying Landforms and Soils by Aerial Photographs

In the process of analyzing aerial photographs to obtain information on the engineering characteristics of soils, the first and perhaps the most important step is to identify the landform. The landform may consist of hills, valleys, plains, terraces, beaches, dunes, and other topo­ graphic features largely created by the forces of erosion. The im­ portance of the landform lies in its relation t...

Automatic Segmentation of Aerial Photographs

Truck Detection from Aerial Photographs

This paper presents a method for extraction and recognition of trucks from aerial photographs. A new method, mean shift image segmentation, is employed to extract truck shadow and boundary information. After a conversion of the boundaries into vector data, an enclosing minimum area rectangle is fit to each boundary. These rectangles are input as candidates into a designed Hopfield Neural Networ...
