Embedded ArUco: a novel approach for high precision UAV landing
Ch. 9438855.
This paper presents a novel approach for precise UAV landing using visual sensory data. A new type of fiducial marker called embedded ArUco (e-ArUco) was developed specially for a task of a robust marker detection for a wide range of distances. E-ArUco markers are based on original ArUco markers approach and require only ArUco detection algorithms. The applicability of developed markers was validated using UAV landing experiments in a virtual environment. Both a developed marker and a landing algorithm were implemented within the ROS framework and tested in the Gazebo simulator. According to our virtual experiments, an average landing accuracy was 2.03 cm with a standard deviation of 1.53 cm.

Audio-visual speech recognition (AVSR) gains increasing attention as an important part of human-machine interaction. However, the publicly available corpora are limited, particularly in driving conditions with prevalent background noise. Research so far has been collected in constrained environments, and thus cannot reflect the true performance of AVSR systems in real-world scenarios. Moreover, data for languages ...

We present an approach to evaluate the robustness of pre-trained vision and language (V&L) models to noise in input data. Given a source image/text, we perturb it using standard computer vision (CV) / natural language processing (NLP) techniques and feed it to a V&L model. To track performance changes, we explore the problem of visual ...

Native support for multi-link operation is a key novelty of the future Wi-Fi 7 technology defined by the IEEE 802.11be standard, which is currently under development. With the 6 GHz band recently granted for Wi-Fi operation, the novel multi-link feature enables simultaneous usage of multiple wide channels. Thus, it multiplies the capacity of Wi-Fi networks ...

Western culture tends towards panoptical vision of the world where human being (1) occupies the place of a lonely and tragic observer of the “world picture”. Though culture’s relying on visual perspective may be quite efficient in matters of technology, it is not immune to a certain kind of optical illusion, which asserts the essential ...

Decision making in the field of limiting anthropogenic impacts on the climate system, including climate itself, requires the estimates of consequences. The assessment of the confidence of estimates is important for the reliable justification of the decisions, in particular for the risk analysis. Such an approach was developed in scientific reports of the Intergovernmental Panel ...

This article proposes a mutual adaptation of the procedure for extracting digital watermark from video sequences and fingerprinting code decoding. Proposed solution includes two interrelated techniques. The first one is a usage of “soft” decision making instead of “hard” decision during watermark extraction. This means that the additional information on extracted bit reliability will be ...

Why Do Mathematicians Need Different Ways to Present Mathematical Objects? The Case of Cayley Graphs
Irina S., Topoi 2010 Vol. 29 No. 1 P. 41–51
This paper investigates the role of pictures in mathematics in the particular case of Cayley graphs—the graphic representations of groups. I shall argue that their principal function in that theory—to provide insight into the abstract structure of groups—is performed employing their visual aspect. I suggest that the application of a visual graph theory in the ...

According to the orthodox conception, mathematicalknowledge is obtained by a combination of mathematicalintuition and deduction: the truth of the axioms is intui-tively given, and theorems are obtained from axioms bylogical inference. Intuition and deduction are viewed astwo separate modules of mathematical thought, and theycan be studied largely independently of each other. Butthere are reasons why this view has come under increasingpressure. ...
