The recognition and classification of the remote sensing image is a key technology in the application of remote sensing image, which has been one of the research hotspots. Extreme learning machine (EML), is a kind of machine learning method, which has advantages of fast learning speed and good generalization capability, and has been getting more and more attention from the researchers. Based on the...
Twenty-first century as an important symbol of the era of the knowledge economy and big data, Internet and networking have a rapid development and have become indispensable data sources in people's lives. Besides, because of its convenience and quickness, these are increasingly applied in more and more aspects. Among them, POI as a true representative of the geographical entity on the network map...
With the development of information technology and the rising requirement of remote sensing data by society, we hope to build a sharing and pubic platform to realize the interoperation of remote sensing data among different systems. This paper proposes the model of Remote Sensing Data Service System based on Enterprise Service Bus to realize the sharing of data and service. Applying the Service Oriented...
An extreme drought was occurred in Northern China in spring, 2009. MODIS data were used in this paper because of its' almost real time and large covered area. Because the subsurface of Northern China is bare soil or scarce vegetation covered area in spring, thermal inertia model which is suitable for this kink was used in this paper. Our results showed that most areas of the Henan province were in...
The Lab Intelligent Monitoring System based on S3C2440 ARM microprocessor and embedded Linux has been designed to accomplish the remote monitoring of the parameters and video images of environment in the Laboratory. The embedded database SQLite manages the data collected by sensor networks. A system program based on Qt/Embedded and Linux drivers realizes the local management of environmental data...
The resource of remote sensing data is rich, their formats and resolution are very different, it is necessary to take some approach to fuse the data. The technique of Principal Components Transform fuses data by replacing the first principal component with the high resolution image after the principal component analysis of multi-spectrum image and then carry on the Principal Components Inverse Transformation...
Independent Component Analysis (ICA) is an effective approach to the separation of blind signal, and has attracted broad attention and has be successfully used in many fields. The fundamental, target functions and practical algorithm of Independent Component Analysis are discussed. Then, by modifying the performance of FastICA algorithm are merged into one iteration of M-FastlCA. The M-FastICA algorithm...
