Abstract

These three lectures cover rather independent subjects. Elementary methods of filtering of digital images are described in a simple way with particular reference to smoothing and sharpening of images. Some simple geometric transformations are described. The use of control points for actual calculation of the transformation functions is explained. Some methods of resampling digital images are described and discussed. The importance of exogenous (i.e. not remotely sensed data) is inhanced. It is also discussed how to store and process these data in a remote sensing environment, to make them compatible with digital images.
