Unmanned aerial vehicles (UAVs) have garnered significant attention from the research community during the last decade, due to their diverse capabilities and potential applications. One of the most critical functions that drones must execute efficiently is navigation in real-world environments. This paper presents a decentralized approach for enabling unmanned aerial vehicles (UAVs) to navigate safely in unknown environments and avoid obstacles. Leveraging the Optimal Reciprocal Collision Avoidance (ORCA) algorithm, implemented in the Robot Operating System (ROS), our method facilitates conflict detection and resolution in 2D environments. Through simulations using ROS, Gazebo, and Iris drones, we validate the effectiveness of our approach in scenarios with initial trajectory conflicts. Our work addresses the pressing need for UAVs to autonomously plan and execute safe flights, laying the groundwork for enhanced UAV capabilities in various real-world applications. The simulation results demonstrate the efficiency and robustness of our approach. © 2024 IEEE.

In healthcare, remote sensing technologies are popular for smart patient health monitoring. Real-time health assessment and early intervention are possible using remote sensing data from wearable sensors and imaging equipment. However, processing and analysing huge remote sensing data are complex. Task scheduling improves processing workflow for accurate and fast health monitoring. This research offered the optimised task scheduling of remote sensing data processing for smart patient health monitoring, to describe the processing activities such as data preparation, task scheduling algorithms, and decision-making involved in data analysis from remote sensing. We used datasets associated with Internet of Things (IoT) devices that patients wear as sensors on their wrists. We used min–max normalisation to standardise the data’s scale after preprocessing the data and choose the task scheduling algorithm methods to distribute work among resources effectively. We proposed the multi-objective dwarf mongoose optimised with Deep Q Network (MODMO-DQN), which aims to address the task scheduling issue for remote sensing data processing in the Internet of Things by monitoring vital sign data of faraway patients. Next, to optimise the e-health services, an optimisation module built on top of MODMO-DQN is developed. The experiment compares the variation in completion time in the remote sensing data process. The results showed that the proposed perform to compare the existing methods. This will make it possible to evaluate the suggested works in terms of throughput, latency, energy usage, and task scheduling efficiency. The performance analysis shows that the recommended method is successful and may be a feasible and efficient solution to track patient vital sign data in Internet of Things-based e-Health. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Automatic timetable generation is a complex optimization problem with practical applications in various domains such as education, healthcare, and event management. The challenge lies in efficiently scheduling activities while satisfying numerous constraints and objectives. In this study, we propose an OptiSchedule algorithm for automatic timetable generation. The algorithm employs a combination of heuristic search techniques and metaheuristic optimization methods to iteratively improve timetable solutions. It starts with initializing a timetable grid and iteratively refines the solution by generating neighbouring solutions and selecting the most promising ones based on an evaluation function. Through extensive testing and validation, our OptiSchedule algorithm demonstrates significant improvements in timetable quality and efficiency compared to existing approaches. The algorithm effectively minimizes conflicts, optimizes resource utilization, and balances workload distribution. Furthermore, it provides flexibility for users to input constraints and preferences, allowing customization to specific scheduling requirements. The OptiSchedule algorithm represents a significant advancement in the field of automatic timetable generation. Its ability to produce high-quality schedules while considering complex constraints makes it a valuable tool for educational institutions, healthcare facilities, and businesses alike. By streamlining scheduling processes and optimizing resource allocation, OptiSchedule contributes to improved operational efficiency and overall organizational performance. Through rigorous experimentation and evaluation, our study demonstrates the effectiveness of the OptiSchedule algorithm in improving timetable quality and reducing scheduling overhead. Compared to traditional methods, OptiSchedule generates timetables with fewer conflicts and better resource utilization, leading to enhanced productivity and satisfaction among stakeholders.

Journal of Ambient Intelligence and Humanized Computing 2024年第9期15卷 3275-3287页

Digitization offers a solution to the challenges associated with managing and retrieving paper-based documents. However, these paper-based documents must be converted into a format that digital machines can comprehend, as they primarily understand alphanumeric text. This transformation is achieved through Optical Character Recognition (OCR), a technology that converts scanned image documents into a format that machines can process. A novel top-down character segmentation approach has been proposed in this work, involving multiple stages. Our approach began by isolating lines from handwritten documents and using these lines to segment words and characters. To further enhance the character segmentation, a Raster Scanning object detection technique is employed to isolate individual characters within words. Thus, the character segmentation results are integrated from the results of the vertical projection and raster scanning. Recognizing the significance of advancing digitization of handwritten documents, we have chosen to focus on the regional languages of Assam and Andhra Pradesh due to their historical and cultural importance in India’s linguistic diversity. So, we have collected datasets of handwritten texts in Assamese and Telugu languages due to their unavailability in the desired form. Our approach achieved an average segmentation accuracy of 93.61%, 85.96%, and 88.74% for lines, words, and characters for both languages. The key motivation behind opting for a top-down approach is two-fold: firstly, it enhances the accuracy of character recognition, and secondly, it holds the potential for future use in language/script identification through the utilization of segmented lines and words. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

The primary aim of identifying the binding motifs in gene regulation is to understand the transcriptional regulation molecular mechanism systematically. In this study, the (, d) motif search issue was considered which entails finding the length motifs which differ by at most d substitutions. However, identifying the high-quality pattern (, d) is challenging. It is intended to address the above problem with motif discovery and handle it using the proposed algorithm S2F (Segmentation to Filtration) based on the qPMS (quorum Planted Motif Search) algorithm model. From the entire DNA sequences, five percent are chosen at random to be used in the motif discovery process. This random sub segment (subseg) portion is split up into base, sub k-mers, and its sizes (motif length ()) are determined by the iterative approach. Corresponding to the sizes of and d (mutations), the k-mers are chosen which participated in filtration techniques and the base k-mer count and frequency are updated. The highest frequency of k-mer is recognized as the motif. The algorithm’s performance was evaluated using the two real datasets Escherichia coli cyclic AMP receptor protein (CRP) and mouse Embryonic Stem Cell (mESC) ChIP-seq (Chromatin Immuno Precipitation) dataset. Results from the experiments show that S2F can identify the motifs and appear faster compared to previous state-of-the-art PMS (Planted Motif Search) and qPMS algorithms.

Hodgkin's lymphoma (HL), a cancer of the lymphatic system, the immune system of the body, affects 1 million people every year. Although very curable, yet in advanced-stage HL, prognostic indices may help recommend the correct treatment to patients. The International Prognostic Score (IPS) is currently the most broadly recognized tool for risk classification of HL. Even though the IPS is still commonly used, it may no longer provide an accurate assessment of the outcomes of advanced-stage HL patients. The IPS does not consider the density of Reed-Sternberg cells despite them being a distinctive feature of HL. In this paper, we propose ARIERS, a system that extracts Regions of Interest (ROI) of reed sternberg cells (RSC) and other blood cells in the histopathology image of a patient of HL using computer vision, which can further be used to estimate the density of RSCs which in turn can improve the prognosis. © 2024 IEEE.

This study presents a comprehensive approach leveraging cutting-edge technologies such as YOLO object recognition, Faster R-CNN, and SVM-based AQI computation. The system integrates YOLOv7 for real-time rubbish classification, facilitating swift and precise trash sorting and disposal decisions. Additionally, it employs Faster R-CNN for fog density analysis, enabling thorough estimations of air pollution levels. To calculate the Air Quality Index (AQI), support vector machine (SVM) algorithms combine various air quality indicators, ensuring thorough and accurate assessments. Enhanced trash classification capabilities enable more accurate evaluation of the environmental impacts of waste management systems. By integrating fog density monitoring with AQI calculation, the approach offers comprehensive trend analysis of pollution, aiding in the formulation of data-driven environmental policies and effective pollution management measures. Furthermore, the system evaluates soil quality, complementing its waste management and pollution control functions. Despite its advancements, the system faces challenges in real-world implementation, including data acquisition, model training, and system integration. Addressing these challenges is critical for realizing the full potential of integrated waste management and pollution control systems. © 2024 IEEE.

With the large number of CCTV cameras located worldwide, ensuring people's safety has become much easier. Despite this, it is impossible to keep track of 100s of CCTV cameras simultaneously. Therefore, deep learning methods of violence detection from surveillance footage have been proposed to reduce human intervention. This solution presents a comparison of the performance of three-dimensional (3D) Convolutional Neural Networks (CNNs), VGG networks, and MobileNet models combined with Long Short-Term Memory (LSTM) units and Multi-Stream Networks to detect violence in CCTV video footage, providing a comprehensive analysis of these models based on accuracy, hardware requirements, and other performance metrics essential to real-world applications. The majority of the existing systems are trained on violent footage from sports or movies, the models in this solution are trained on a combination of datasets consisting of CCTV footage which provides an accurate representation of real-world surveillance footage, thus improving model accuracy. Existing research does not study the effect of combining very deep CNN models like VGG with advanced techniques like multi-stream models. This solution explores the impact of integrating such models to create a more robust solution. All the models proposed and evaluated have produced accurate results and are capable of identifying violence based on surveillance footage, with an accuracy of up to 98.46%. Unlike other solutions that do not take into account the memory and prediction time of different models, this solution identifies the ideal model depending on the available resources and infrastructure, helping make a decision based on real-world requirements. © 2024 IEEE.

Facial expression recognition is a challenging task when neural network is applied to pattern recognition. Most of the current recognition research is based on single source facial data, which generally has the disadvantages of low accuracy and low robustness. In this paper, a neural network algorithm of facial expression recognition based on multimodal data fusion is proposed. The algorithm is based on the multimodal data, and it takes the facial image, the histogram of oriented gradient of the image and the facial landmarks as the input, and establishes Convolutional Neural Network (CNN) designed to extract features from facial image, neural network designed to extract features from facial Landmarks and Neural Network (LNN) designed to extract features from Histogram of gradient (HNN), three sub-neural networks to extract data features, using multimodal data feature fusion mechanism to improve the accuracy of facial expression recognition. Experimental results show that, the algorithm has a great improvement in accuracy, robustness and detection speed. Copyright © 2024 Inderscience Enterprises Ltd.

Facial Expression Analysis and Recognition (FEAR) are evolutionary concepts in the field of computer vision and artificial intelligence to develop human–computer interaction. Over the last decade, technology is leading human lives through online in various fields like education, medical, entertainment, shopping, etc. FEAR is a challenging task for the researchers while deploying the system in real-time applications as human expressions are not general in all situations and with all content. In experimentation of expression analysis and recognition, a feature extraction, database, and similarity measure play a key role to justify whether the system achieves the required target or not. This paper represents the various benchmark approaches for feature extraction, expression classification, and facial expression datasets like JAFFE, RaFD, CK +, MMI, FER2013 etc., and their features, representations, and challenges given in the investigations according to the researchers requirement so far. Retrospectively, discusses the suggestions and recommendations of the forthcoming mechanisms to reduce the semantic gap to analyze the expressions in general. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.
