Satellite imaging

The study of advanced computer technique to analyse satelitte images is a growing area as cameras are widely used for earth observation. More specifically, the PERCEPTION project is developping an expertise in the study of linear puschbroom cameras. These cameras are used in passive remote sensing from space as they provide high resolution images. The pushbroom camera is a linear sensor that takes 1-D images at several time instants. The sensor sweeps out a region of space; stitching together all 1-D images gives a complete 2-D image of the observed scene. Several interesting computer vision issues are of interest, such as the calibration of such cameras, or the estimation of satellite vibrations from these sensors.
