Image processing for high resolution satellite and aerial data

The last few years have seen the launch of several high-resolution satellites, and many more are planned in the near future. In parallel, new high-resolution CCD cameras for use in aerial photography have been developed. In this paper, we focus on this new optical high-resolution data. We present the challenges arising from the new technology in the introduction, and then concentrate on three applications to SPOT5 and Pleiades HR simulations and aerial images: deconvolution, urban area extraction, and road network detection. In conclusion, we comment on future prospects.
