In this paper the problem of a vision system implementation for autonomous flying agents is considered in the context of industrial inspection tasks performed by unmanned aerial vehicles. A syntactic algorithm of a two-dimensional object vectorization and recognition is proposed. An algorithm of twodimensional map recognition has been introduced as well. The algorithms have been tested by using...

This paper presents a method to summarize massive spacecraft telemetry data by extracting significant event and change patterns in the lowlevel time-series data. This method first transforms the numerical timeseries into a symbol sequence by a clustering technique using DTW distance measure, then detects event patterns and change points in the sequence. We demonstrate that our method can succes...

Among the algorithms used for the retrieval of SMC from microwave sensors (both active, such as Synthetic Aperture Radar-SAR, and passive, radiometers), the artificial neural networks (ANN) represent the best compromise between accuracy and computation speed. ANN based algorithms have been developed at IFAC, and adapted to several radar and radiometric satellite sensors, in order to generate SM...

around 30–50m. These features are often associated with three-dimensional upper ocean dynamics. We have conducted a number of studies involving in-situ observations in the Straits of Florida during SAR satellite overpass. The data include examples of sharp frontal interfaces, wakes of surface ships, internal wave signatures, as well as slicks of artificial and natural origin. Atmospheric proces...

A recently proposed method for automatic radiometric normalization of multiand hyperspectral imagery based on the invariance property of the Multivariate Alteration Detection (MAD) transformation and orthogonal linear regression is extended by using an iterative re-weighting scheme involving no-change probabilities. The procedure is first investigated with partly artificial data and then applie...

Coupling effects of Earth oblateness and direct solar radiation pressure on the motion of an artificial satellite are evaluated. Secular and periodic terms are retained up to order three and two respectively, where the coefficient 2 J of the second zonal harmonic of the geopotential is considered of first order. The solution revealed the existence of secular terms at order three that arises fro...

Extracting knowledge from existing sources of information is a key development area to unlock previously unknown relationships between specific data points. Data mining is a technique that uses artificial intelligence methods to extract previously unknown relationships. It becomes a factor when large volumes of data, such as in the case of clusters of satellites, need to be analyzed. Data minin...

This paper presents Computer Aided Architectural Design (CAAD) system utilizing the technologies of artificial intelligence (AI) and image processing. The goal is to create a CAAD system that detects buildings from satellite images and produces computer city models allowing the system's users to manipulate the models utilizing machine learning technology. The flexibility and usability of the sy...

From 1960's to 1970's, the Chinese Army built some fortified artificial hills. Some of them are located in the Inner Mongolia, Western China. These large fortresses are surrounded by moats. For some of them it is still possible to see earthworks, trenches and ditches, the planning of which could have a symbolic meaning. We can argue this result form their digital outlining, obtained after an im...

abstract particular matters which are referred as pm contents in air are one of the main indexes in air pollution studies. pms are consisted of water, solid particles with aerodynamic radius less than 10 micrometer or less than 2.5 micrometer. the main aim of this study is to find possibility of the usage of modis images for estimation of pm10 concentration of dust storms. to achieve this goal ...
