The research emphasizes the creation of a powerful and efficient system for the automaticextraction of contact information from physical calling cards through computer vision and information extraction techniques. This is achieved by integrating Tesseract Optical Character Recognition (OCR) with the YOLO (You Only Look Once) object detection algorithm, which acts as a dynamic combination for text and relevant elements identification and digitization from calling cards. The developed system uses client-server architecture to enable communication and data processing seamlessly. The server handles computationally intensive tasks such as object detection, OCR processing, and data validation while the client side has an interactive user interface that enables easy uploading of images and retrieval of structured contact information. The optimizations include this: YOLO is customized for detecting particular card elements (name, phone number, email) and enhancing the capabilities of Tesseract OCR to improve effectiveness for text extraction from varied card formats or fonts in the system. It is designed to be scalable and efficient, processing large datasets without affecting accuracy. This approach not only eases the digitization of calling card details into databases but also goes a long way in contributing to the domains of computer vision, object detection, and mechanized information extraction. It extends the scope to broad applications in automated data entry, customer relationship management (CRM), and digital archival. It takes forward for AI-driven sustaining technologies the integration of these techniques into practical solutions by overcoming the challenges of data extraction from real-world images. © 2024 IEEE.

Metaphors are a common communication tool used in our day-to-day life. The detection and generation of metaphors in textual form have been studied extensively but metaphors in other forms have been under-explored. Recent studies have shown that Vision-Language (VL) models cannot understand visual metaphors in memes and adverts. As of now, no probing studies have been done that involve complex language phenomena like metaphors with videos. Hence, we introduce a new VL task of describing the metaphors present in the videos in our work. To facilitate this novel task, we construct and release a manually created dataset with 705 videos and 2115 human-written captions, along with a new metric called Average Concept Distance (ACD), to automatically evaluate the creativity of the metaphors generated. We also propose a novel low-resource video metaphor captioning system: GIT-LLaVA, which obtains comparable performance to SoTA video language models on the proposed task. We perform a comprehensive analysis of existing video language models on this task and publish our dataset, models, and benchmark results to enable further research. © 2024 Association for Computational Linguistics.

Wind energy is a resource that is environmentally sustainable, crucial component needed for wind energy production. Accurate estimation of wind speed is essential for many applications. This paper proposes the Hybrid deep learning model for wind speed forecasting. The hybrid wind speed model was developed based on the Convolutional Neural Network (CNN) and Long Short Term Memory (LSTM). CNN model includes a series of Convolutional layers followed by pooling layers, designed to extract relevant features from the input sequences, final dense layers of the network facilitate the prediction of future wind speeds. LSTM model is used for improving the accuracy of short - term prediction. Using the wind dataset from the National Renewable Energy Laboratory (NREL) in Muppandal, Kanyakumari, Tamil Nadu, wind speed was determined. The performance of the proposed model (CNN-LSTM) is quantified using Mean Absolute Error (MAE), Mean Root Square Error (RMSE), and Mean Absolute Percentage Error (MAPE). The experimental results proved that the proposed hybrid model outperformed the benchmarks models being the RNN, CNN, GRU and LSTM. © 2024 IEEE.

India depends heavily on agriculture for its survival. Rainfall is crucial to agriculture. Predicting rainfall has become a significant issue recently. People are made aware of the possibility of rain and are better prepared to protect their crops by taking preventative measures when rain is predicted. Making an accurate rainfall prediction has always been challenging, but in recent years, because of climatic variability and change, it has become even more challenging. The effectiveness of classification systems for predicting rainfall has soared. For the purpose of predicting rainfall in the Indian states, this research employs a variety of categorization techniques. The classification algorithms are Logistic Regression by Lesso, Decision Tree, Light GBM, Extreme Gradient Boosting, Random Forest Method, K Nearest Neighbor Technique, Naive Bayes and Support Vector Machine Techniques. Dataset, which included several meteorological parameters, was obtained via Kaggle. With a testing data ratio of 70:30. Based on precision, accuracy, recall, f1-score, and execution time, the efficacy of the classification algorithms was assessed. There are few challenges with the existing system with data and with accuracy which are the major problems in predictions and to understand which algorithm is best especially for rainfall prediction our aim is to find measures for all possible algorithms and provide a conclusion saying the algorithm that fits for rainfall prediction. © 2023 IEEE.

The goal of the proposed system is to identify whether a video has endured software manipulation or not. This system specially deals with identifying deepfake videos from real ones. As new techniques emerged to make deepfake, a handful of photos and fake videos are spreading at an alarmingly increasing rate, which is indistinguishable from the real ones to the naked eye. The proposed system uses CNN with transfer learning to predict the degree of manipulation involved. The user uploads the video that they want to check;the video is saved on the server, and then they experience the process of deepfake detection. Then the user is presented with a plot showing the degree of the fakeness of the video and the accuracy of the prediction. The user can then assume based on the plot, as it shows the frames where manipulation might be involved. © 2024 IEEE.

In today's interconnected digital ecosystem, protecting cyber-physical systems is critical. STPA-Sec is a systematic method that allows to analyze system designs and identify vulnerabilities in those designs from the onset and throughout the system lifecycle. In this article, we describe a carefully designed metamodel that accommodates the concepts and steps of the method. We translate key concepts from STPA-Sec into a metamodel, with the intention of facilitating a more structured and disciplined application of STPA-Sec. We demonstrate the advantage of using the metamodel in two case studies. This article offers a step forward in the rigorous application of STPA-Sec.

As healthcare services have become increasingly digitized, Electronic Health Records (EHRs) have become widely adopted, providing seamless data exchange among providers. Conventional EHRs, however, are extremely vulnerable to cyber threats because patients' sensitive data is centralized and transmitted electronically. The paper proposes a decentralized, privacy-preserving framework for managing EHRs on blockchains in order to address these security and privacy concerns. Using cryptographic techniques, such as homomorphic encryption and zero-knowledge proofs, the proposed system enhances security and ensures data integrity. Additionally, the model facilitates scalable, efficient, and secure access to patient records through the integration of cloud-based storage and blockchain. Using smart contracts, we also ensure compliance with healthcare regulations by regulating access control and authentication. As a result of performance evaluations, the proposed approach is demonstrated to be feasible, and the advantages it offers in terms of security, privacy, and efficiency are highlighted. © 2025 The Authors

Neural Computing and Applications 2024年第24期36卷 15149-15164页

The survival rate of lung cancer relies significantly on how far the disease has spread when it is detected, how it reacts to the treatment, the patient’s overall health, and other factors. Therefore, the earlier the lung cancer diagnosis, the higher the survival rate. For radiologists, recognizing malignant lung nodules from computed tomography (CT) scans is a challenging and time-consuming process. As a result, computer-aided diagnosis (CAD) systems have been suggested to alleviate these burdens. Deep-learning approaches have demonstrated remarkable results in recent years, surpassing traditional methods in different fields. Researchers are currently experimenting with several deep-learning strategies to increase the effectiveness of CAD systems in lung cancer detection with CT. This work proposes a deep-learning framework for detecting and diagnosing lung cancer. The proposed framework used recent deep-learning techniques in all its layers. The autoencoder technique structure is tuned and used in the preprocessing stage to denoise and reconstruct the medical lung cancer dataset. Besides, it depends on the transfer learning pre-trained models to make multi-classification among different lung cancer cases such as benign, adenocarcinoma, and squamous cell carcinoma. The proposed model provides high performance while recognizing and differentiating between two types of datasets, including biopsy and CT scans. The Cancer Imaging Archive and Kaggle datasets are utilized to train and test the proposed model. The empirical results show that the proposed framework performs well according to various performance metrics. According to accuracy, precision, recall, F1-score, and AUC metrics, it achieves 99.60, 99.61, 99.62, 99.70, and 99.75%, respectively. Also, it depicts 0.0028, 0.0026, and 0.0507 in mean absolute error, mean squared error, and root mean square error metrics. Furthermore, it helps physicians effectively diagnose lung cancer in its early stages and allows spe
