Introduction

Wentian Du is a prominent inventor based in Hefei, China. He has made significant contributions to the field of target detection, particularly through his work with synthetic aperture radar (SAR) technology. With a total of 2 patents, Du's innovations are paving the way for advancements in this critical area of research.

Latest Patents

Du's latest patents include a "Contextual visual-based SAR target detection method and apparatus" and a "storage medium." These patents describe a method that involves obtaining an SAR image and inputting it into a target detection model. The model is designed to position and recognize targets within the SAR image, yielding a detection result. The method enhances a two-way multi-scale connection operation through top-down and bottom-up attention, which guides the learning of dynamic attention matrices. This enhancement improves feature interaction across different resolutions, allowing for more accurate extraction of multi-scale target feature information. The result is a significant improvement in detection performance with minimal increase in parameters and computational load.

Another notable patent is the "synthetic aperture radar (SAR) image target detection method." This method utilizes the anchor-free target detection algorithm YOLOX as its framework. Du reconstructs the backbone feature extraction network from a lightweight perspective, replacing depthwise separable convolution in MobilenetV2 with a combination of ordinary and depthwise separable convolutions. This innovative approach reduces the number of channels in the feature map while enhancing the extraction of features, ultimately improving the detection of SAR targets through an attention enhancement pyramid attention network.
