Study on Change Detection Automatically Based on Similarity Calibration
land use and land cover change very quickly at different scales all over the world. Remote sensing becomes a major tool to acquire information of LUCC. In recent years
the continuing development of remote sensing technology provides us a large amount of remote sensing data at high spatial
spectral and temporal resolutions. Advances in remote sensing science and diversity in high resolution data hold great promise for improving the precision of information extraction and change detection
which also make change detection of land use and land cover at different scales from global scale to local scale more difficult. However
conventional remote sensing change detection techniques are inefficient due to the high spatial heterogeneity of inner objects in the image
more texture
more details and clear edges. Moreover
the requirement for real time and effective change detection methods and large size of high spatial resolution imagery cells for development of more automatic techniques of change detection. The method of change detection based on integration of change vector analysis and similarity calibration is presented for high spatial resolution data. It can be used to detect the change of building and street quickly and automatically. In this paper
we present details of the method of change object extraction and verification The methods are illustrated with an airborne linear scanner sensor image over the suburb of Tokyo city
Japan. The result of change detection will be compatible to complexity and fuzzy degree of change of object in high spatial resolution imagery at different times
which is distinguishable to the results using conventional change detection
in which the result only provide "change" and "no-change". The experimental results suggest that change detection based on object similarity calibration is more reliable
efficient than post classification change detection using high spatial resolution imagery.
