THE USE OF VARIOGRAMS IN REMOTE-SENSING .1. SCENE MODELS AND SIMULATED IMAGES

Variograms are the tool used to link models of ground scenes to spatial variation in images. Explicit variograms are calculated for simple models of ground scenes consisting of randomly located discs on a continuous background. By incorporating the effect of the IFOV of the sensor through a process called regularization, explicit variograms for images of these scene models are derived. Verification of the explicit variograms is accomplished by simulating images that match the assumed scene model and sensor parameters and calculating empirical variograms for these images.
