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)
Bayes Classifiers are widely used currently for recognition, identification and knowledge discovery. The fields of application are, for example, image processing, medicine, chemistry (QSAR). However, by mysterious way the Naive Bayes Classifier usually gives a very nice and good presentation of recognition. More complex models of Bayes Classifier cannot(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)
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)
DHoPLLS (a web server that identifies closed loops, which constitute a structural basis for the protein domain hierarchy. The server was created in 2005 year on basis Prof. Trifonov's lab in Genome Diversity Center, Institute of Evolution at University of Haifa. It is based on theory of loop-lock structure developed by Prof. Trifonov's group in Weizmann(More)
