This work aimed to study computationally simple method of saliency map calculation. Research in this field received increasing interest for the use of complex techniques in portable devices. A saliency map allows increasing the speed of many subsequent algorithms and reducing the computational complexity. The proposed method of saliency map detection based on both image and frequency space analysis. Several examples of test image from the Kodak dataset with different detalisation considered in this paper demonstrate the effectiveness of the proposed approach. We present experiments which show that the proposed method providing better results than the framework Salience Toolbox in terms of accuracy and speed.

Abstract. Objective of this research is creation of an algorithm of a control system of the modes of the intensive hygrothermal influence (IGI) in the conditions of a vacuum when performing the corresponding operations: moistening; the subsequent, if necessary, cyclic drying from within preparation of top of footwear; damp thermal treatment on universal installation with adjustable parameters of a working environment. For assessment of quality of the intensified hygrothermal impact on preparations of top of footwear the integrated criteria of efficiency of processes were used. Ensuring automatic control of parameters of processes of IGV on preparations of top of footwear in universal vacuum installation will allow to control quality of preparations upon transition from performance of one operation to another according to standard manufacturing techniques of footwear.

The paper considers the feasibility of using a jet aeration system for water and energy saving in the operation of sweepers, irrigation and washing machines, channel washing machines. On the basis of physical models of air-water jets are made to the calculation of process parameters of aeration of the working fluid, to establish the possibility of reducing the consumption of water supplied to the washing chamber sewer machine 15%, when the pressure of the water inlet to the water system is 0.17 ATM. To establish the limits for regulating the parameters of the aeration process of liquid jets, a complete factor experiment was conducted for 6 significant factors. The resulting mathematical model of the water jet aeration process is adequate to the process under study. The limits of regulation of the process in question are determined: compressed air pressure, Q=0.3 - 0.35 MPa; nozzle size z=5-8 mm; angle of attack of the abrasive jet α=55-60°; distance to the treated surface L=120-180 mm; appropriate reduction of the diameter of the water jet during aeration -15÷ 50%. It is shown that the water saving in the washing chamber on the example of the KO-502B2 channel washing machine based on the ZIL-433362 chassis when using the aeration system will be, and the pump power will decrease by 1709 watts. Analysis of the main trends in the development of municipal equipment has shown that the provision of resource-saving technologies for cleaning, maintenance of urban areas and pipelines is one of the priorities in the development of housing and utilities.
