遥感图像数据规模大,光照、遮挡等情况复杂,目标密集、尺度不一以及缺乏大量带标注图像用于训练深度网络等特点对遥感图像分割的完整性和正确性造成了更大的挑战。针对深度卷积网络中因多次卷积造成分辨率显著下降,像素类别预测精度降低的问题,本文在深度卷积编码—解码网络的基础上设计了一个采用完全残差连接和多尺度特征融合的端到端遥感图像分割模型。该模型具有两方面优点:首先,长距离和短距离的完全残差连接既简化了深层网络的训练,又为本层末端融入了原始输入信息,增强了特征融合。其次,不同尺度和方式的特征融合使网络能够提取丰富的上下文信息,应对目标尺度变化,提升分割性能。本文通过对ISPRS Vaihingen和Road Detection数据集做数据扩充并进行实验,分别从平均IOU、平均F1值两方面对模型进行评价。通过与目前先进的模型以及文献中的研究成果进行比较,结果表明本文所提模型优于对比模型,在两个数据集上的平均IOU分别达到了85%和84%,平均F1值分别达到了92%和93%,能够有效提高遥感图像目标分割的完整性和正确性。 相似文献

The Photogrammetric Society was formed in 1952. The Council of the Society considered that the twentieth anniversary was a good point at which to record the events which led to its formation and the significant occasions and decisions which have taken place since 1952. Consequently, Paul Lamboit was invited to compile this History. He has placed the birth and development of the society within the national and international photogrammetric context and his record of the deliberations which took place between 1947 and 1952 will be of particular interest to historians of our subject.
This account was first published in a limited edition in 1971. Sufficient interest has since been expressed to prompt a wider circulation through publication in the Photogrammetric Record .
The author served the Society continuously in several official capacities from 1953 to 1969 and he was elected to Honorary Membership in 1969. 相似文献

A scholarly account of the formative discussions, the founding and the first 20 years of the Photogrammetric Society was published in 1971 and republished in 1974. This present review concentrates on the latter years of the life of the Photogrammetric Society prior to its merger with the Remote Sensing Society in 2001.
The authors joined the Photogrammetric Society in 1960 and were conspicuous in its affairs for many years. Although both occupied the Society's presidential chair, they also fulfilled several other roles in its efficient management. Atkinson's first contribution to the Photogrammetric Record was published in 1968 and Newton's in 1971. 相似文献
