With the rapid development of remote sensing technology, high-resolution remote sensing images have become an important means in multiple fields such as environmental monitoring, urban planning, and agricultural management. However, the volume and complexity of remote sensing image data pose significant challenges for traditional analysis methods, including low computational efficiency and the reliance on manual feature design for feature extraction when dealing with large-scale data. In recent years, deep neural networks (DNNs), with their powerful capabilities in automatic feature extraction and pattern recognition, have demonstrated outstanding performance in remote sensing image analysis. This study systematically reviews the application of deep neural networks in key tasks such as remote sensing image classification, object detection, semantic segmentation, and change detection, and analyzes the current research status and progress both domestically and internationally in this field. Additionally, this study also explores cutting-edge research directions such as multi-modal data fusion, model lightweighting and real-time optimization, as well as the interpretability of deep learning models.
