An algorithm for page layout analysis (segmentation) is suggested in the paper. It allows whitespace between text blocks to be detected on a document page. The algorithm could be used in document analysis and recognit...

In this paper we put forward a logical-structure method for recognition of objects on high resolution satellite images. This approach is based on logical reasoning with the use of structural description of objects. A ...

Because of increased requirements to the angular resolution of contemporary and perspective orbital telescopes, their large geometric dimensions elastic vibrations of the construction may exert substantial influence on the quality of information received. In this situation, construction and investigation of the dynamic model of the telescope, which is equipped with an optic-electronic system of high resolution, becomes one of the main stages in its designing. The process of constructing of the mathematical model may be subdivided into the two stages. Stage one implies elaboration of the analytical (computational) model on the stage of system's designing. Stage two implies refining the structure, dimension and parameters of the analytical model. This is done because of the results of testing the article under the conditions, which are ultimately close to real exploitation conditions of the construction. Modeling of weightlessness in the process of testing the total construction on land represents a rather complicated problem [1]. The paper proposes a new approach to the problem of refining parameters of the analytical model based on the data obtained by the measuring system (MS), which allows measuring the current state of the construction in the process of its exploitation. This approach presumes decomposition of the process of adjustment of parameters of the computational model into the two stages. Stage one is the stage of model's identification: determination of its eigenfrequencies and dumping coefficients from the data obtained by the measuring system under the conditions of either real construction's exploitation or experimental exploitation of its field-oriented sample. Stage two, which implies correction of the computational model, presumes refining of its parameters on the basis of results of the identification, while proceeding from the conditions minimal corrections. The technique of correcting the matrices of coefficients of the linear model in the state
We develop a canonical global optimality theory based on operating with the set of solutions for the Hamilton-Jacobi inequalities that parametrically depend on the initial (or final) position. These solutions, called ...
