Digital image processing, remote sensing and GIS: technical development and applications for earth science and environmental monitoring.

·  Development of novel sub-pixel image feature matching technology based on FFT phase correlation for precise image co-registration, motion measurement, super quality low occlusion DEM (digital elevation model) generation from very narrow baseline to conventional wide baseline stereo images and super resolution image reconstruction. The technology and the software package developed have found wide applications in topographic mapping, quantitative change detection, mobile objects detection and sub-pixel measurement of terrain deformation resulted from earthquakes.  

·  Advanced digital image processing. Methodology, technique and software development.

·  Interferomatric SAR (InSAR) technology and applications for geohazard study: rapid erosion, sand encroachment, subsidence and earthquake/neo-tectonic deformation.

· Remote Sensing and GIS applications for regional geohazard assessment, neo-tectonic history of fault evolution and geological and terrain type mapping.
