Remote Sensing Image Change Detection Based On Domestic Resource Satellite

Remote sensing image change detection is an important aspect for remote sensingapplications,the main aim is detect and judge the area or target whether has change at differenttime,and determine what type of change.Remote sensing image change detection is still at theprimary stage,because of the complexity and difficulty of detection,at present there are nointernational research breakthrough,lack of a unified theory,and the degree of automation islow.According to one of the difficulties in the change detection of remote sensing imageautomatic degree is not high,combining the MFC program design and open source visualLibrary, write an automatically change detection software,the software has a visual interface and image processing function.This paper introduces theprocess detection algorithm in detail.Finally, through remote sensing image change detectionexperiments testing the effect of software and analyze the problems in the process of changedetection.At present,the change detection applications are mainly using foreign existing maturecommercial software like ERDAS or ENVI.This kind of software is powerful and the result ofdetection is ideal,but need high price to buy,and still need to manually set parameters duringthe steps before the detection.This method restricts the level of automation of changedetection.The innovation of this article is overcome the traditional remote sensing imagechange detection depends on the platforms,using the dialog box based on Microsoftfoundation class library as a visual interface,and open source visual library that has highperformance and completely open source for image processing,in the least human interventionfinally complete automatic change detection.
