RUDN University mathematician named the main problems of autopilots when detecting pedestrians
Cars and other self-driving vehicles have already begun to enter everyday life. However, for this technology to be widely adopted, several fundamental characteristics need to be improved. One of them is pedestrian detection. For this, deep learning technologies are used — artificial neural networks. RUDN mathematicians with colleagues from Egypt, Saudi Arabia and China analyzed the latest research in this direction.
“In recent years, autonomous vehicles have become increasingly popular. They improve safety and convenience, reduce fuel consumption, reduce traffic congestion and accidents, save costs and increase reliability. However, before they are fully deployed on the roads, several primary tasks need to be solved. Precise detection of pedestrians is a very difficult task. Deep learning technologies show great potential for solving this problem. We have compiled an overview of the problems of pedestrian detection and the latest advances in solving them using deep learning methods,” Ammar Muthanna, PhD, Junior Researcher at the Research Center for Modeling High-Tech Systems and Infocommunications, RUDN University.
Mathematicians have drawn attention to three main problems that arise when detecting pedestrians using deep learning — obstacles, poor image quality, multispectral images. The latter is a series of images of the same object, but obtained in different ranges. For example, the usual optical image and in the infrared range. It is assumed that the data is obtained from lidars and cameras, from where the deep learning model comes. Mathematicians have reviewed the different approaches that are used to build such models, and called their advantages and disadvantages.
RUDN mathematicians noticed that different construction methods give not only different results, but also different time and accuracy of work. For example, more modern methods give a more accurate answer, but it takes more time. Therefore, the scientists concluded, it is important to implement an approach that can find a balance between accuracy and speed. And one that will meet practical goals. Mathematicians also noticed that the data available for training is not heterogeneous enough and may not give a complete picture. For example, images in the optical range work better during the day, and in the infrared — in the dark. For the algorithm to be efficient around the clock, large heterogeneous data sets are needed for training.
Among the goals for future research in this area, RUDN mathematicians named the detection of small and obstructed objects, work in poor lighting, a combination of 3 D and 2 D approaches. The researchers also suggest focusing on improving speed and accuracy.

A Center for Green Diplomacy was created based on the RUDN Institute of Environmental Engineering. Among the goals is the integration of the results of scientific and practical activities into the development of international relations in the environmental sphere. The center's specialists will also accompany the corporate sector in solving various environmental problems.
RUDN summarized the results of the scientific competition "Project Start: work of the science club ". Students of the Faculty of Physics, Mathematics and Natural Sciences have created a project for a managed queuing system using a neural network to redistribute resources between 5G segments. How to increase flexibility, make the network fast and inexpensive and reach more users — tell Gebrial Ibram Esam Zekri ("Fundamental Computer Science and Information Technology", Master's degree, II course) and Ksenia Leontieva ("Applied Mathematics and Computer Science", Master's degree, I course).
