This paper deals with the error analysis of a novel navigation algorithm that uses as input the sequence of images acquired from a moving camera and a digital terrain (or elevation) map (DTM/DEM). More specifically, it has been shown that the optical flow derived from two consecutive camera frames can be used in combination with a DTM to estimate the(More)
An algorithm for pose and motion estimation using corresponding features in omnidirectional images and a digital terrain map is proposed. In previous paper, such algorithm for regular camera was considered. Using a digital terrain (or digital elevation) map (DTM/DEM) as a global reference enables recovering the absolute position and orientation of the(More)
HoPLLS (Hierarchy of protein loop-lock structures) (http://leah.haifa.ac.il/~skogan/Apache/mydata1/main.html) is a web server that identifies closed loops-a structural basis for protein domain hierarchy. The server is based on the loop-and-lock theory for structural organisation of natural proteins. We describe this web server, the algorithms for the(More)
An algorithm for pose and motion estimation using corresponding features in images and a digital terrain map is proposed. Using a Digital Terrain (or Digital Elevation) Map (DTM/DEM) as a global reference enables recovering the absolute position and orientation of the camera. In order to do this, the DTM is used to formulate a constraint between(More)
We consider a modified formulation for the recently developed new approach in the continuum solvation theory (Basilevsky, M. V.; Grigoriev, F. V.; Nikitina, E. A.; Leszczynski, J. J. Phys. Chem. B 2010, 114, 2457) which is based on the exact solution of the electrostatic Poisson equation with the space-dependent dielectric permittivity. Its present(More)

We present four methods for recovering the epipolar geometry from images of smooth surfaces. In the existing methods for recovering epipolar geometry corresponding feature points are used that cannot be found in such images. The first method is based on finding corresponding characteristic points created by illumination (ICPM—illumination characteristic(More)
