FEA-Swin: Foreground Enhancement Attention Swin Transformer Network for Accurate UAV-Based Dense Object Detection

Blog Article

UAV-based object detection has recently attracted a lot of attention due to its diverse applications.Most of the existing convolution neural network based object detection models can perform well in common object detection cases.However, due to the fact that objects in UAV images are spatially distributed in a very dense manner, these methods have limited performance for UAV-based object detection.In this paper, we propose a novel transformer-based object detection model to improve the accuracy of object detection in UAV images.

To detect dense objects competently, an advanced foreground enhancement attention Swin Transformer (FEA-Swin) framework is simply southern cat shirt designed by integrating context information into the original backbone of a Swin Transformer.Moreover, to avoid the loss of information of small objects, an improved weighted bidirectional feature pyramid network (BiFPN) is presented by designing the skip connection operation.The proposed method aggregates feature maps from four stages and keeps abundant information of small objects.Specifically, to balance the detection accuracy and efficiency, we introduce an efficient neck of the BiFPN network kenya tree coral for sale by removing a redundant network layer.

Experimental results on both public datasets and a self-made dataset demonstrate the performance of our method compared to the state-of-the-art methods in terms of detection accuracy.
