Abstract To address the issues of complex background interference, loss of fine details in small objects and the high demand for detection efficiency in aerial image object detection, a depth-reshaping enhanced network(DR-ENet) is proposed. Firstly, the traditional downsampling methods are replaced by spatial depth-reshaping techniques to reduce information loss during feature extraction and enhance the ability of the network to capture details. Then, a deformable spatial pyramid pooling method is designed to enhance the adaptability of network to object shape variations and its ability to recognize in complex backgrounds. Simultaneously, an attention decoupling detection head is proposed to enhance the learning effectiveness for different detection tasks. Finally, a small-scale aerial dataset , PORT, is constructed to simultaneously consider the characteristics of dense small objects and complex backgrounds. Experiments on three public aerial datasets and PORT dataset demonstrate that DR-ENet achieves performance improvement, proving its effectiveness and high efficiency in aerial image object detection.
