In recent years, image processing methods based on convolutional neural networks (CNNs) have achieved very good results. At the same time, many branch techniques have been proposed to improve accuracy. Aiming at the change detection task of remote sensing images, we propose a new network based on U-Net in this paper. The attention mechanism is cleverly applied in the change detection task, and the data-dependent upsampling (DUpsampling) method is used at the same time, so that the network shows improvement in accuracy, and the calculation amount is greatly reduced. The experimental results show that, in the two-phase images of Yinchuan City, the proposed network has a better antinoise ability and can avoid false detection to a certain extent.
近年来,基于卷积神经网络(CNN)的图像处理方法取得了非常好的效果。同时,人们提出了许多分支技术来提高准确率。针对遥感图像的变化检测任务,本文提出了一种基于U-Net的新网络。将注意力机制巧妙地应用于变化检测任务中,同时采用数据依赖上采样(DUpsampling)方法,使网络在准确率上有所提高,且计算量大大减少。实验结果表明, 在银川市的两期影像中,所提网络具有较好的抗噪能力,且在一定程度上能够避免误检。
