Abstract
We compute morphological medians hierarchically between the spatial fields [e.g., digital elevation models (DEMs)] represented with similar sizes via grayscale morphology-based interpolations. These hierarchically generated sequential morphological medians facilitate construction of morphing-like sequence between the source and the target spatial fields to visualize the spatiotemporal changes that have occurred between discrete time-intervals and episodic intervals. Two DEMs of similar sizes but belonging to two different regions are considered as source and target spatial fields further to 1) demonstrate morphology-based algorithm to generate all possible sequential morphological medians and 2) create morphing depicting source-DEM transforming into target-DEM. Application of morphological interpolation to DEM morphing is shown for the first time.
