Particular attention is paid to metrics that are used in the field of natural language processing - BLUE (evaluates quality based on a comparison of the result obtained by a model and a person), NIST (based on the BLUE metric), METEOR (based on the harmonic mean of unigrams of accuracy and completeness), ROUGE (. The article presents a new metric, which is based on subjective assessments. The subjective estimates used in the considered metric are collected using pairwise comparison in the form of evaluation scales. The article also proposes an algorithm for generating music based on automatic models of working with ABC notation, models of distributive semantics and generative models of deep neural networks - Transformers. The new quality metric (SS-metric) presented in the article is used to assess the quality of the proposed algorithm for generating music in comparison with the solutions offered by humans and baseline models. Music generation based on the baseline model builds a continuation of a musical fragment by randomly selecting bars from the first half of the musical fragment. During the experiments, it was found out that the SS-metric allows you to formalize and generalize subjective assessments, this can be used to assess the quality of various objects.","PeriodicalId":135912,"journal":{"name":"Proceedings of the 31th International Conference on Computer Graphics and Vision.

It is noted that the main part of the design and engineering activity belongs to the development of the geometric component of electronic product model. It is concluded that the development of algorithms, methods and software to simplify the creation or improve the quality of geometric data is relevant. The terms introduced by the State Standard are analyzed and it is shown that at different stages of design and engineering activities, the geometric component of electronic product model includes a plurality of geometric and graphic models. At the same time, from the point of view of constructive geometric modeling, closely associated with design and engineering activities, there is no fundamental difference between flat and three-dimensional geometric models, and they should be considered uniformly. The concept of a constructive geometric model, combining electronic geometric models and electronic drawings, is introduced. A constructive geometric model can simultaneously contain flat, threedimensional and multidimensional geometric data, which can be displayed using different computer graphics tools. Text and visual forms are offered to represent constructive geometric models. The features and areas of applying a visual and text presentation of constructive geometric models are given. The article considers the use of constructive geometric models to automate the creation of electronic geometric models, as well as verification of electronic drawings and models.","PeriodicalId":135912,"journal":{"name":"Proceedings of the 31th International Conference on Computer Graphics and Vision.

The features of the C3D FairCurveModeler geometric modelling kernel are based on engineering and computational geometry, as well as the NURBS theory. The C3D FairCurveModeler has a great potential for industrial modelling applications, as it can improve a product's characteristics by refining its shape quality. The C3D FairCurveModeler release applications for CAD and Microsoft Excel platforms; the WebFairCurveModeler cloud product developed based on libraries of the C3D geometric modelling kernel are offered to accelerate the implementation of the C3D FairCurveModeler features in the engineering practice.

Two configurations are considered: a pair of counter-rotating vortices and a pair of co-rotating vortices. In the case of counterrotating vortices the wings attack angle was 10 degrees. In the case of co-rotating vortices the attack angle of one of the wings was 10 degrees, the attack angle of other one was -10 degrees. Numerical data were obtained in the domain of 10 wing chords downstream from a wings axis by a computational model based on the URANS equations with SA turbulence model. Numerical simulations were performed on the hybrid supercomputing system K-60 at the Keldysh Institute of Applied Mathematics RAS using the developed software package ARES for 3D turbulent flows modeling on high performance computing systems. The main simulation was performed on 224 cores.

Such a training ground is currently considered as an instrumental platform for testing technologies for training intelligent agents in conditions of varying complexity in order to subsequently transfer the developed methods to real objects for solving practical problems. As an example, the control of a robotic device operating in an enclosed space is considered. The article describes the technology of reducing the volume and dimension of the processed data in order to increase the responsiveness to changes in the situation and the development of solutions for moving a robotic device. The technology is based on the preprocessing of video images for the formation of a training sample, as well as the procedure and results of deep learning of a convolutional neural network. The paper uses an open source library of OpenCV computer vision algorithms implemented in C / C++. It is shown that focusing on the selection of object boundaries can significantly reduce the amount of data for analyzing the situation and increase the speed of decision-making by the robot to move.","PeriodicalId":135912,"journal":{"name":"Proceedings of the 31th International Conference on Computer Graphics and Vision.

The features of the operation of virtual, augmented and mixed reality systems, the principles of image formation of the virtual and real worlds and the problems of their combination are described. For mixed reality systems, the basic principles of building systems, their specifics and the principles of forming an image of the real world are described. The specific reasons for the formation of the conflict of visual perception in mixed reality systems are considered. There are three main causes of conflict that can be overcome in modern mixed reality systems: the position and type of the light source; the correct formation of shadows from virtual sources on the image of real-world objects; and the intensity of radiation, including the radiation diagram. A method for evaluating the correctness of the formation of illumination of virtual objects in a mixed reality system and its influence on the quality of visual perception is proposed. To evaluate the proposed methodology, a number of test scenes with correct and incorrect lighting of virtual objects have been developed. The assessment of the quality of visual perception was carried out on a test group of 24 people with experience in computer graphics systems. The quality was evaluated on a good/bad scale. Based on the results of the expert assessment, a conclusion was formed that defines the requirement for building a lighting system for virtual objects in mixed reality systems.","PeriodicalId":135912,"journal":{"name":"Proceedings of the 31th International Conference on Computer Graphics and Vision.

Apply materials from an external library, which is a * .blend file with a set of materials based on the names of objects in the scene. Export the resulting scene to WebGL 2.0, using the Babylon.js framework, with the ability to play the resulting animation, which includes traditional animation control buttons, setting the playback speed, the ability to move through animation frames, as well as access to the view from the Blender 3D camera, there where its animation takes place. An interactive list of scene objects is created in the html page, which was automatically generated from the names of Blender 3D scene objects using Jinja2, when you click on the checkbox of the list items, the object is hidden / displayed. Mechanical gear assemblies imported from T-FLEX CAD 3D 17 in * .stl format were used as examples of evaluating the addon's performance. Some features of creating add-ons for Blender 3D are discussed. A comparison of the Three.js library and the Babylon.js framework is given in order to use them to create interactive engineering applications.
