The application of Artificial Intelligence (AI) in stock price prediction has demonstrated significant advancements, with Machine Learning and Deep Learning techniques proving highly efficient in this domain. Two widely adopted architectures for stock price prediction are the Long Short Term Memory (LSTM) and Gated Recurrent Unit (GRU) models. Recognizing the potential impact of financial news sentiment on forecasting, this study investigates whether incorporating such sentiment yields superior results compared to relying solely on historical stock prices. Accurate predictions in the financial market are challenging due to its inherent high volatility and non-linear nature. To contribute insights into the effectiveness of various deep learning architectures, a comparative analysis was conducted on Long Short-Term Memory (LSTM), Gated Recurrent Unit (GRU), Convolutional Neural Network (CNN), and the Prophet model. The evaluation focused on three companies listed on the National Stock Exchange (NSE). The study employs the Mean Squared Error (MSE) metric to rigorously assess and compare the models’ performance. The results of the comparative analysis provide valuable implications for precision in stock price prediction within the context of market volatility and non-linearity. The study adds to the growing body of research on the application of AI in financial forecasting, emphasizing the importance of considering sentiment analysis alongside traditional approaches for enhanced predictive accuracy. © 2024 IEEE.

Efficient navigation of emergency response vehicles (ERVs) through urban congestion is crucial to life-saving efforts, yet traditional traffic systems often slow down their swift passage. In this work, we introduce Dynamic Priority Signalling System (DyPSS), an intelligent, multi-layered traffic management solution designed to minimize ERV delays by creating "green corridors"at traffic signals. Using technologies like fog computing, cloud computing, global positioning system and deep learning, DyPSS adjusts traffic lights instantly to clear congestion as an ERV approaches. Simulation testing was conducted using SUMO and it demonstrated DyPSS's potential to significantly reduce ERV travel time in dense urban settings with minimal disruption to general traffic flow. This system could drastically improve emergency response by reducing delays and helping responders reach their destinations faster, potentially saving more lives. © 2025 IEEE.

Our methodology emphasizes the development of a Vision Transformer model trained on a comprehensive dataset, enhanced with both image data and keypoint information, leveraging the capabilities of the Mediapipe library. To improve the model’s ability to generalize, we applied advanced augmentation strategies, including ImageDataGenerator, among others. Through extensive experimentation, involving rigorous hyperparameter optimization across numerous epochs, we sought to determine the most effective model configuration. The results of our validation process revealed a promising evaluation loss of 0.2941 and an impressive accuracy rate of 97.52%. This integration of data augmentation techniques with ViT transformers establishes a groundbreaking framework in the field of ISLR, underscoring its significant potential for practical implementation and marking a substantial progression in the technology for sign language recognition. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.

High Dynamic Range Imaging for Dynamic Scenes Based on Multi-Level Spike Camera

IEEE Transactions on Circuits and Systems for Video technology 2025年第6期35卷 5394-5406页

Spike camera is a retina-inspired neuromorphic camera which can capture dynamic scenes of high-speed motion by firing a continuous stream of spikes at an extremely high temporal resolution. The limitation in the current design is that each spike only represents the arrival of a fixed amount of photons. It can not deal with strong light areas in which the amount of accumulated photons reaches the pre-specified threshold multiple times within a single readout interval. In this paper, we propose a new spike camera model of high-speed imaging for high dynamic range scenarios. In this scheme, each pixel accumulates the incoming photons persistently and generates a new type of spike stream in which each spike symbol may be associated with different levels, indicating the arrival of different amounts of photons since the last readout. This enables the camera to support dynamic scenes with wider dynamic range. To achieve this, we propose a two-level buffer mechanism, one for photon accumulation and one for spike-firing encoding. We use a register to hold the number of spike-firings which has not been read out yet. At each readout time, the major part in the counter is read out via a carefully designed exponential encoding and the counter is updated. Such encoding and readout strategy enables a very efficient expansion of the dynamic range using a small number of encoding bits. Furthermore, we propose an image reconstruction scheme for the proposed camera, utilizing both spike intervals and spike levels to recover the light intensity. We incorporate Mamba and propose a temporal-spatial selective scan mechanism to extract temporal-spatial correlation within spike streams. We employ a pyramid adaptive filtering and alignment module to achieve coarse-to-fine feature alignment. Experimental results show that the proposed scheme can achieve better imaging quality and outperform the existing spike camera in high dynamic range scenarios. © 1991-2012 IEEE.

The Sign Language Recognition System (SLRS) is a cutting-edge technology that aims to enhance communication accessibility for the deaf community in India by replacing the traditional approach of using a human interpreter. However, the existing SLRS for Indian Sign Language (ISL) do not focus on some major problems including occlusion, similar hand gesture, multi viewing angle problem and inefficiency due to extracting features from a large sequence of frame that contains redundant and unnecessary information. Therefore, in this research paper an occlusion robust SLRS named Multi Featured Deep Network (MF-DNet) is proposed for recognizing ISL words. The suggested MF-DNet uses a histogram difference based keyframe selection technique to remove redundant frames. To resolve occlusion, similar hand gesture, and multi viewing angle problem the suggested MF-DNet incorporates pose features with Convolution Neural Network (CNN) features. For classification the proposed system uses Bi Directional Long Shor Term Memory (BiLSTM) network, which is compared with different classifier such as LSTM, ConvLSTM and stacked LSTM networks. The proposed SLRS achieved an average classification accuracy of 96.88% on the ISL dataset, 99.06% on the benchmark LSA64 dataset and 99.85% on the WLASL dataset. The results obtained from the MF-DNet is compared with some of the existing SLRS where the proposed method outperformed the existing methods. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

Grape farming is a globally significant agricultural practice, but grapevines frequently encounter viral, fungal, and bacterial infections that compromise crop quality and yield. Conventional disease detection methods are labor-intensive and require significant expertise. This study investigates deep learning techniques, focusing on EfficientNet models, to automate grape leaf disease identification and classification. The transfer learning approach was applied to train and fine-tune EfficientNet models on a publicly available dataset with four classes: black rot, leaf blight, esca, and healthy leaves. A model performance was measured through accuracy and loss metrics. EfficientNetB0 achieved accuracy of 92.45% and 96.73%, and loss of 0.197 and 0.098, on training and validation data, respectively. However, EfficientNetB5 and EfficientNetB7 gave validation accuracies of 96.07% and 96.39%, respectively. The accuracy and loss trends demonstrate that EfficientNetB0 outperforms the other two counterparts. This approach highlights the potential of EfficientNetB0 for accurate, efficient grape disease detection and classification. © 2025 IEEE.

The advent of technologies like Deep Learning has revolutionized human interaction, transcending language and disability barriers. Sign Language Recognition (SLR) systems have emerged as vital tools, facilitating seamless communication between individuals and between humans and machines through Interfaces. However, existing SLR systems pose significant challenges, including the demand for high accuracy, low latency, simplicity in development and deployment, lightweight design for edge compatibility, and efficient resource utilization during training. Addressing these challenges necessitates developing a system that balances training data accuracy, ease of training, and resource efficiency. Conventional Deep learning approaches often rely on high-dimensional image datasets for training HGR models, resulting in trade-offs between latency, accuracy, complexity, and resource requirements. To mitigate these challenges, this paper harnesses the capabilities of Google Mediapipe to extract a 21-point hand landmark vector from each training image. By leveraging this low-dimensional data, we train model that are accurate, lightweight, less complex, and exhibit low latency, making them compatible with edge devices. The hand gesture images were collected for several gestures, such as peace, okay, and stop. These images will be converted to landmark vectors using Mediapipe. These landmark points were used to train the Deep Neural Network architecture developed in Tensorflow. The model was trained with each hand gesture assigned with a common word in English and the proposed model was tested with a live webcam stream. The proposed model is developed in Python in the Google Colab IDE with the help of libraries and frameworks like OpenCV, Tensorflow and Google Mediapipe. The proposed model outperforms current state-of-the-art approaches by achieving an accuracy of 9 4. 8 8 %. © 2024 IEEE.
