The panchromatic bands of Landsat 7, SPOT, and IRS satellite imagery provide an opportunity to evaluate the effectiveness of texture analysis of satellite imagery for mapping of land uselcover, especially forest cover. A variety of texture algorithms, including standard deviation, Ryherd-Woodcock minimum variance adaptive window, low pass etc., were applied to moving 3x3 and 7x7 pixel windows. ...

We introduce a new image texture segmentation algorithm, HMTseg, based on wavelet-domain hidden Markov tree (HMT) models. The HMT model is a tree-structured probabilistic graph that captures the statistical properties of wavelet coeecients. Since the HMT is particularly well suited to images containing singularities (edges and ridges), it provides provides a good classiier for textures. Utilizi...

This work presents a method to output the 3D structure of an urban area from only one aerial photo. The reconstruction is based on the inverse process done when a parallel projection is used to construct a twodimensional image from a three-dimensional object. A new algorithm for reconstruction is developed and implemented. It recovers depth information by identification of object height on the ...

Although Talon® baits containing brodifacoum have been used successfully in eradicating rats from some of New Zealand's offshore islands, little is known about any environmental effects of this toxin. Invertebrates, blackbirds, soil, and water at intervals of two days to nine months were sampled to determine whether brodifacoum residues were present after aerial distribution of Talon® 20P cerea...

A new family of self-calibration additional parameters (APs) is presented for calibrating airborne camera systems. We point out that photogrammetric self-calibration can to a very large extent be considered as a function approximation problem in mathematics. Based on the mathematical approximation theory, a novel family of so-called Legendre APs is developed based on the orthogonal Legendre pol...

The Direct Linear Transformation (DLT) model requires 3-D object space control points to estimate the full set of its parameters that can be used to recover exterior orientation parameters. The use of DLT in a planar object space leads to a rank deficient model. This rank deficient model leaves the DLT defined up to a 2-D projective transformation, which makes the explicit solution of the exter...

A fully operational automatic interior orientation (AUTO_IO) for digital aerial images based on a modified Hough Transform for rough localization of fiducial marks and Least Squares Matching for precise measurement is introduced in this paper. For cameras with fiducial mark identification symbols, e.g. as used in Leica RC30 cameras, the program is capable to determine the orientation of the pho...

Automatic recognition and reconstruction of buildings from aerial and space images is of great practical interest for many of applications such as cartography and photo-interpretation. Building detection is the first and very difficult step in building recognition and reconstruction. It is to find buildings and separating them from the background in the presence of distractions caused by other ...

In connection with the development plan of USK campus II area, it is necessary to map area support and complete data. Mapping an Unmanned Aerial Vehicle (UAV) a strategy or way for large-scale mapping faster more efficient time. It can save time compared using conventional survey methods. Ground Control Point (GCP) measurements are carried out geodetic GNSS improve accuracy/correction geometry ...
