Special Issue Information

Dear Colleagues,
Deep image restoration and understanding play a crucial role in enhancing the performance of modern sensing systems by improving the quality and interpretability of visual data captured by various sensors. The increasing deployment of imaging sensors in applications such as medical diagnostics, environmental monitoring, autonomous systems, and security has underscored the importance of restoring degraded images and extracting meaningful information under challenging conditions.

Advancements in deep learning technologies have significantly transformed this field, enabling the development of robust methods that address noise, blur, low resolution, and other distortions inherent to sensor-captured images. Of particular interest is the integration of deep neural networks with sensor data, leading to novel solutions that enhance image quality and understanding in resource-constrained and real-time environments. For instance, incorporating few-shot learning techniques has demonstrated the potential to generalize across limited sensor datasets, paving the way for efficient and scalable implementations.

This Special Issue aims to highlight cutting-edge research in deep image restoration and understanding within the context of sensing technologies. We invite contributions that explore innovative deep learning methodologies, theoretical advancements, and practical applications, particularly in sensor-driven fields such as medical imaging, remote sensing, smart cities, and autonomous systems.

By emphasizing the interplay between sensor technologies and deep learning, this Special Issue seeks to provide a comprehensive platform for advancing state-of-the-art solutions that enhance the functionality and reliability of imaging sensors in diverse applications

Driver drowsiness remains a critical factor in road safety, necessitating the development of robust detection methodologies. This study presents a dual-framework approach that integrates a convolutional neural network (CNN) and a facial landmark analysis model to enhance drowsiness detection. The CNN model classifies driver states into “Awake” and “Drowsy”, achieving a classification accuracy of 92.5%. In parallel, a deep learning-based facial landmark analysis model analyzes a driver’s physiological state by extracting and analyzing facial features. The model’s accuracy was significantly enhanced through advanced image preprocessing techniques, including image normalization, illumination correction, and face hallucination, reaching a 97.33% classification accuracy. The proposed dual-model architecture leverages imagery analysis to detect key drowsiness indicators, such as eye closure dynamics, yawning patterns, and head movement trajectories. By integrating CNN-based classification with precise facial landmark analysis, this study not only improves detection robustness but also ensures greater resilience under challenging conditions, such as low-light environments. The findings underscore the efficacy of multi-model approaches in drowsiness detection and their potential for real-world implementation to enhance road safety and mitigate drowsiness-related vehicular accidents.
