Abstract

In this paper we presents an algorithm which generates its high-resolution DTM using a low-resolution DTM of the sea floor terrain and fractal theory. The fractal dimension of each patch region divided from the DTM ís extracted and then with this information and original data, each cell region in the patch ís interpolated using the midpoint displacement method and a medían filter is incorporated to generate natural and smooth sea floor surface The effectiveness of the proposed algorithm ís tested on a fractal terrain map.
