摘要：

This paper presents the application of different spectral methods, like Fourier series and polynomial-based expansions, to Digital Elevation Models (DEMs) in order to fuse their content. Two different fusion techniques: 1) a filter-based one and 2) a weighted average of expansion coefficients, are examined. Their performance is evaluated by using both ground-truth lidar data as well as fusion quality measures. The results point out that polynomial-based spectral expansions perform better than the traditional Fourier approach.
