CHAPTER 2

The Statistics of Remote Sensing Images

This chapter studies the statistical characteristics of remote sensing images and compares them with those of standard photographic images. The issue of spatial, spectral and spatial-spectral redundancy is analyzed in detail through illustrative examples in real remote sensing images. The statistical behavior presented here is key in applications such as coding or restoration of remote sensing imagery.
