...…algorithms is based on the utilised primitives, namely, image intensity patterns (windows composed of grey values around a point of interest) or features (for example, edges and regions), leading to area-based matching (ABM) or feature-based matching (FBM) algorithms (Remondino et al., 2008)....

...Tests in close range applications have been reported, for example, by Remondino et al. (2008, 2009) and Remondino and Menna (2008), although not always supported by accurate reference data....

...Some of the results have been reported in Wolff (2009). The key problem with such tests, which were done with aerial images with footprints of 8 and 20 cm, is the generation of sufficiently good reference data....

...There are three types of features: 1) Interest Points [14], [15]: Interest point detectors are generally divided into contour-based methods, which search for maximal curvature or inflexion points along the contour chains; signal-based methods, which analyze the image signal and derive a measure which indicates the presence of an interest point; and methods based on template fitting which try to fit the image signal to a parametric model of a specific type of interest point (e....
