[Abstract]:With the rapid development of remote sensing technology, remote sensing image change detection has been widely used in many fields, such as urban change, natural disaster assessment, environment, landform monitoring, agroforestry, resource change, military reconnaissance and so on. On the basis of a large number of innovative algorithms in the field of remote sensing image change detection, Matlab2009a and Visual C++6.0 Integrated development environment is used as a tool to develop a fully functional remote sensing image change detection software platform.
This paper explores the detection algorithm of remote sensing image change based on Markov random field, and focuses on the key technologies involved in developing the application software platform of remote sensing image change detection. Firstly, the basic theory of Markov random field is briefly introduced. On this basis, a Markov random field based on Markov random field is discussed. At last, the effectiveness of the method is illustrated by the simulation experiment. Secondly, the development background, interface design and function design of the application software platform for remote sensing image change detection are introduced. Finally, the key technologies involved in the development of remote sensing image change detection software platform are expounded. The key technologies of the software platform include multi thread programming, dynamic link library technology, Matlab and VC hybrid programming technology and memory mapping technology. Multithreading can handle the task of long running time in the background to avoid the situation of the dead machine when the program runs; the dynamic link library can make the program easier to upgrade and maintain. The hybrid programming technology of VC and Matlab combines the powerful numerical computing power of Matlab and the excellent window program development ability of VC to develop high quality software, and can quickly read and process large capacity remote sensing image data by using memory mapping file technology.
