本发明提出基于改进U?net网络的无人机麦田遥感图像分割方法,通过加入注意力模块的方式加强目标特征学习,同时通过改进损失函数的方法对权重进行重分配,从而解决遥感图像中目标背景类别分布不均的问题;最后,结合形状先验信息对分割结果进行进一步修正。本发明利用采集的无人机麦田数据集进行训练和模型验证,试验结果表明,分割准确率和平均交并比分别达93.31%和73.91%,较好解决了田埂分割遮挡和缺失等问题。
To detect wind turbines precisely and quickly in very high resolution remote sensing images (VHRRSI) we propose target mask U-Net. This convolution neural network (CNN), which is carefully designed to...
Taking Xiamen city as the study area this research first retrieved surface net radiation using meteorological data and Landsat 5 TM images of the four seasons in the year 2009. Meanwhile the 65 differ...
Satellite data from Moderate Resolution Imaging Radiometer (MODIS) is currently being used to extract net primary production (NPP) at global scale. Over the years, small scale on-ground flux tower mea...
Japan International Cooperation Agency (JICA) has initiated a three year-project of JICA NET Distance Education on remote sensing and GIS for developing countries since 2004FY in cooperation with Japa...
Image segmentation is the foundation of further object-oriented image analysis, understanding and recognition. It is one of the key technologies in high resolution remote sensing applications. In this...
The present study aims to assess the effect of agricultural developments on inter-annual variations in the agricultural Net Primary Productivity (NPP) of selected districts of the semi-arid region of ...
Daily net surface radiation fluxes are estimated for Indian land mass at spatial grid intervals of 0.1 degree. Two approaches are employed to obtain daily net radiation for four sample days viz., Nove...
Polar orbiting satellites (MODIS and SPOT) have been commonly used to measure terrestrial Net Primary Productivity (NPP) at regional/global scale. Charge Coupled Device (CCD) instrument on geostationa...
The net ecosystem productivity (NEP) is the estimates of net carbon exchanges between the vegetation-soil system and the atmosphere. Estimates of NEP could play important role in defining a terrestria...
High-accuracy estimation of the net primary production (NPP) of vegetation is important in the study of the carbon cycle and the biotic response to climatic warming. This study estimated the NPP of ve...
