Contourlet, one of multiscale analysis tool with great property of multi-directionality, locality and sparse approximation, is an excellent 2-dimentional image description approach. Contourlet can be employed as a remote sensing image fusion approach to improve spatial resolution and application through precise capture of edge information from panchromatic image and injection of that into multispectral...
Monitoring urban growth and change is an important issue for urban planning and disaster management. In this study, three temporal TerraSAR-X images are used to monitor the urban changes. The difference and correlation coefficient between two images are calculated with a sliding window. Then a new factor that composites the difference and correlation coefficient is proposed to detect the changes....
In this paper we introduce new model for efficient building extraction and change detection in sparsely populated remotely sensed image pairs. In the two time layers interacting marked point processes recognize the buildings while a priori constraints and low level similarity information are involved in the model. The exploration is accelerated through a non-uniform object birth process, which proposes...
