The aim of this article is to analyze the impact of adaptive histogram equalization of the human eye OCT B-scans on the effectiveness of the classification of pathological changes. Tests were performed on two datasets. The first dataset contains 4 class B-scans (CNV, DME, DRUSEN, and NORMAL) taken with the use of Spectralis Heidelberg device, while the second dataset contains images from two devices (Spectralis Heidelberg OCT and Avanti Optovue OCT) and additionally contains the VMT (i.e., vitreomacular traction) class. The images were subjected to standard histogram equalization and contrast limited adaptive histogram equalization (CLAHE) with various parameters. The classification process was carried out using VGG16 artificial neural network. It can be observed that histogram equalization has no significant impact on improving classification performance. © 2024 Division of Signal Processing and Electronic Systems, Poznan University of Technology (DSPES PUT).

Reactive Collision Avoidance control for Nonholonomic Vehicles and Obstacles of Arbitrary Shape

ASME Letters in Dynamic Systems and control 2024年第3期4卷 031005页

作者： Rodrıǵuez-Seda, Erick J. Department of Weapons Robotics and Control Engineering United States Naval Academy AnnapolisMD21402 United States

Potential field-based collision avoidance algorithms for mobile robots frequently assume vehicles and obstacles to have circular or spherical shapes. This assumption not only simplifies the analysis but also limits the mobility of agents in confined spaces, particularly for vehicles with elongated or irregular shapes. To increase mobility, this letter presents a decentralized collision avoidance framework for nonholonomic systems of unicycle type that considers the non-circular shape and relative orientation of vehicles and obstacles. The framework builds on the concepts of potential field and avoidance functions. However, it proposes using a non-constant minimum safe distance radius that changes based on the shape, relative position, and relative orientation of agents. The control framework is proven to guarantee collision avoidance at all times and is shown, via simulation, to increase the ability of agents to navigate through narrow spaces safely. © 2024 American Society of Mechanical Engineers (ASME).

Journal of Institute of control, robotics and Systems 2025年第3期31卷 187-195页

Traffic surveillance systems are essential for ensuring public safety and optimizing urban traffic flow by accurately detecting, classifying, and monitoring traffic law violations such as illegal parking and jaywalking. However, detecting such violations in dynamic urban environments poses significant challenges due to unpredictable conditions. Traditional camera-based systems excel in capturing visual details but suffer performance degradation under low light, occlusion, or complex intersection scenarios, leading to false positives and missed detections. Therefore, we propose a camera-LiDAR fusion-based traffic violation detection system. LiDAR's independence from lighting conditions complements camera capabilities, especially in night scenarios or occluded environments. Experimental results in a real-world urban environment demonstrate the system’s effectiveness in reducing false positives and missed detections compared to traditional camera-only approaches. This study underscores the potential of sensor fusion to improve traffic management systems and points out future research opportunities in challenging conditions. © ICROS 2025.

Reinforcement Learning for Highway Driving Decision-making Using CDR (Curriculum based Domain Randomization)

Journal of Institute of control, robotics and Systems 2025年第2期31卷 114-123页

Incorrect autonomous driving decisions on highways can lead to traffic congestion and accidents. Therefore, accurate decision-making in highways is essential. However, decision-making in highways is a challenging task due to the complexity of traffic situations. Thus, reinforcement learning is an appropriate approach for decision-making in highways. However, a domain gap often arises between the training and testing environments due to differences in them. Therefore, a curriculum-based domain randomization approach is applied, which progressively adjusts the level of random parameters. The RL model is trained using the SUMO simulator and tested in the MORAI simulator, where white noise is added to simulate real-world conditions. Consequently, applying curriculum domain randomization has the lowest collision rate. © ICROS 2025.

2024 International Russian Automation Conference, RusAutoCon 2024

作者： Margun, Alexey Bui, Van Huan Bobtsov, Alexey Itmo University Control Systems and Robotics Department Saint Petersburg Russia

The paper focuses on developing a finite-time approach for sensors fault detection and isolation in MIMO systems. The proposed solution utilizes the synthesis of a bank of unknown input observers, tailored specifically for each of sensor. A significant advantage of this solution over existing methods is its applicability to plants with any arbitrary relative degree. The paper introduces a modification that ensures finite-time convergence using Kreisselmeier's scheme combined with the dynamic regressor extension and mixing method. This modification guarantees that the convergence of observer estimates - and thus the diagnostic results - occurs within a user-specified timeframe. Additionally, the implementation of filters and threshold settings is discussed to prevent false alarms caused by measurement noise. The effectiveness of the developed approach is validated through computer simulations, confirming its robust performance. © 2024 IEEE.

This study introduces a stochastic model designed to evaluate the long-term degradation of Electronic Security Systems (ESS) as critical components of Physical Protection Systems (PPS). Recognizing the significant financial investments in security systems and the evolving nature of threats, our model aims to provide a more dynamic assessment of PPS effectiveness over time. Traditional methodologies, such as the Estimated Adversary Sequence Interruption (EASI), often overlook the degradation factor, potentially leading to mismanagement and increased vulnerability. Our model incorporates various stochastic parameters, including aging, adversary knowledge growth, and technological improvements, to simulate the decline in system effectiveness. We present a comprehensive computational framework using Python, demonstrating the model’s application through a case study involving different ESS components with varied ages. The results highlight the necessity for proactive maintenance strategies and dynamic policy-making to sustain PPS effectiveness. This paper underscores the importance of integrating degradation factors into PPS evaluation to enhance security infrastructure management against evolving threats. © 2024 IEEE.

As per latest research in the main medical sector, paralysis sight as is sight as observed as one of the main foremost causes of disability in human subjects trailing only behind chronic illnesses such as cancer and heart disease. In this sight as study, we examined health-related signals to uncover potential indicators of paralysis related disability. In collaboration with medical experts, we identified eight crucial parameters that could assist in determining whether an individual shows symptom of paralysis. Our research involved assembling an observational database comprising over 40,000 human subjects, spanning the main period from January 2018 to December 2023. We employed a three-layer Recurrent Neural Network to conduct categorical analyses involving training, validation, and testing phases. Our results suggest that ECG, blood pressure, heart rate and PPG signals are essential in evaluating an individual's risk of paralysis sight as disorders. The main model achieved an impressive accuracy rate of 94.3%, outperforming other models observed during the main study. These observed findings underscore the main potential of advanced machine learning techniques for facilitating the main early detection of paralysis sight as symptoms. By providing timely notifications to healthcare providers and human subjects at risk, our methodology can significantly enhance patient care and outcomes. This sight as research not only enriches the main scientific understanding of paralysis sight as but also offers practical solutions for improving human health through timely intervention strategies. Ultimately aiding in the main prevention of severe consequences associated with this sight as debilitating condition. © 2024 IEEE.
