基于卷积神经网络的高分辨率遥感影像目标边界提取方法OA
High resolution remote sensing image object boundary extraction method based on convolutional neural network
为有效应对高分辨率遥感影像遮挡、旋转等因素对目标边界提取效果的影响,文中提出基于卷积神经网络(CNN)的高分辨率遥感影像目标边界提取方法.以卷积神经网络实现高分辨率遥感影像目标边界提取框架为基础,引入了特征增强模块,避免网络目标边界浅层、深层特征提取时存在语义信息的表征不足以及丢失细节信息问题;同时,优化网络损失函数,通过预处理目标边界图,将其转化为边界信息的概率图,并设定阈值来排除不确定性像素点,增强模型目标边界提取鲁棒性和精确度.实验结果显示,该方法可实现目标边界精准提取且不易受遥感影像旋转影响,在不同遮挡程度下均具备较为优异的目标边界提取能力.
In view of the impact of factors such as occlusion and rotation on object boundary extraction in high-resolution remote sensing images,a CNN-based method for extracting object boundaries from high-resolution remote sensing images is proposed.The high-resolution remote sensing image object boundary extraction framework is implemented by CNN,on the basis of which,a feature enhancement module is introduced to avoid insufficient representation of semantic information and loss of detail information in the shallow and deep feature extraction of network object boundaries.The network loss function is optimized,and the object boundary map is preprocessed and then converted into a probability map of boundary information,and then a threshold value is set to exclude uncertain pixels,so as to enhance the robustness and accuracy of model object boundary extraction.The experimental results show that the proposed method can achieve accurate extraction of object boundaries,and is not easily affected by remote sensing image rotation.In addition,it has excellent ability of object boundary extraction under different degrees of occlusion.
