Special Issue Information

Dear Colleagues,

Recent progress in sensor technologies—ranging from optical, infrared, and event cameras to LiDAR, radar, and multispectral devices—has significantly expanded the possibilities for object detection in real-world scenarios. Image processing and analysis represent the core of these advancements, enabling the accurate and efficient extraction of meaningful information from raw sensor data. Modern approaches combine classical computer vision methods with deep learning techniques to address challenges such as occlusion, varying illumination, real-time performance, and multi-modal data fusion. This Special Issue seeks original research and reviews that explore innovative algorithms and frameworks, and their applications in sensor-based object detection. Potential contributions may include novel data-preprocessing strategies, feature extraction methods, fusion of heterogeneous sensor data, and the deployment of these methods in fields such as autonomous vehicles, robotics, environmental monitoring, and smart surveillance.

This topic aligns with the scope of Sensors by focusing on the integration of sensing devices with advanced image analysis methods to improve the detection, classification, and interpretation of objects in diverse environments, enhancing both the capabilities of sensors and the impacts of their application.

The rising demand for real-time perception in aerial platforms has intensified the need for lightweight, hardware-efficient object detectors capable of reliable onboard operation. This survey provides a focused examination of real-time aerial object detection, emphasizing algorithms designed for edge devices and UAV onboard processors, where computation, memory, and power resources are severely constrained. We first review the major aerial and remote-sensing datasets and analyze the unique challenges they introduce, such as small objects, fine-grained variation, multiscale variation, and complex backgrounds, which directly shape detector design. Recent studies addressing these challenges are then grouped, covering advances in lightweight backbones, fine-grained feature representation, multi-scale fusion, and optimized Transformer modules adapted for embedded environments. The review further highlights hardware-aware optimization techniques, including quantization, pruning, and TensorRT acceleration, as well as emerging trends in automated NAS tailored to UAV constraints. We discuss the adaptation of large pretrained models, such as CLIP-based embeddings and compressed Transformers, to meet onboard real-time requirements. By unifying architectural strategies, model compression, and deployment-level optimization, this survey offers a comprehensive perspective on designing next-generation detectors that achieve both high accuracy and true real-time performance in aerial applications.
