Special attention is drawn to emulation of human vision and photo cameras effects during processing of the images which have very bright areas (with brightness more than an order of magnitude greater than average brightness of the rest of the image). A method of desaturation of the brightest parts of images is suggested. This method provides lowering of the color saturation of each pixel depending on the pixel brightness. The improved method lowers saturation only of the brightest parts of an image. The size of the desaturated part of the image should not exceed 25% of the size of an entire image.","PeriodicalId":409819,"journal":{"name":"GraphiCon'2019 Proceedings.

Modern world is developing in the conditions of transformational transitional processes, when the artificial shell, the technosphere, created by the society becomes the leading life-support system instead of the biosphere. It is a full-fledged participant in the exchange processes between a globalizing technogenic society and transforming nature, which allows us to talk about forming socio-techno-natural laws of developing the world and life. There are no integrative visual models in the world that represent evolutionary changes in three systems simultaneously – society (and man), the technosphere and the technologically transformed biosphere, on the basis of which it is possible to predict the formation of a sustainable future for humanity in connection with the expansion of socio-technonatural processes. The generally recognized visualization methodology must be supplemented by the methodology of the philosophy of the world socio-technogenic development and the change in the evolution of life for a better visual representation and explanation of the transformation processes taking place in the changing world that is becoming post-biospheric. Interdisciplinary philosophical view allows capturing the world in the integrity of its diverse characteristics and at the same time forming a problem field for visualizing transformational processes. The fundamental role of the integration link belongs to information technology, which allows us to represent visually heterogeneous data with the aim of further developing models for the safe development of mankind in the technosphere.","PeriodicalId":409819,"journal":{"name":"GraphiCon'2019 Proceedings.

The purpose of this work is to conduct practical research of methods for key point detection and the optical flow calculation in the problem of determining the unmanned ground vehicle proper motion. For detection method research conduction the image panel containing various distortions typical for follow robot shot was made. It has been educed that among the accounted methods FAST finds the largest number of points within the minimum elapsed time. At the same time image distortions strongly affect the results of the method, which is negative for the positioning of the robot. Therefore the Shi-Tomasi method was chosen for key points detection within a short period of time, because its results are less dependent on distortion. For research undertake a number of video clips by means of the follow robot shot was made in a confined space at a later scale of the odometry algorithm. From experimental observations the conclusions concerning the application of Lucas-Kanade optical flow method tracking the identified points on the video sequence have been made. Based on the error in the results obtained it was implication that monocular odometry cannot be the main method of an unmanned vehicle positioning in confined spaces, but in combination with probe data given by assistive sensors it is quite possible to use it for determining the robotic system position.","PeriodicalId":409819,"journal":{"name":"GraphiCon'2019 Proceedings.

The features of this method are unique capabilities for controlling the parameters of the shock pulse. This allows, in contrast to other dynamic methods of the surface plastic deformation, forming the desired microhardness distribution diagram in the surface layer at a depth of 6- 8 mm, while ensuring the required uniformity of hardening. The need to visualize this method is explained by the complexity of the analytical description of the ongoing wave processes in the shock system and the loading medium. Developing a visualization technique based on a model of the process of wave strain hardening consists of several stages. The stages include setting the initial and boundary conditions of the simulated elements, their physical-mechanical properties, loading conditions, the type of the mesh, the process conditions. The created model allows you to visually track the shock pulse movement after the striker hits the statically pressed waveguide against the loading medium, and at the same time to see the generation of the reflected deformation wave (the tail of the shock pulse) and its effect on the shock system elements and the loading medium. The results will make it possible to develop shock systems with the highest efficiency.","PeriodicalId":409819,"journal":{"name":"GraphiCon'2019 Proceedings.
