Frequency Domain Analysis of Fuzzy B- Spline for 3D Tsunami Visualization from Remote Sensing Data

摘要

This paper utilizes fuzzy B-spline based on frequency domain analysis to visualize 3D tsunami waves from remote sensing satellite data. In doing so, two dimensional Fourier transform (2DFFT) was used to extract the successive tsunami wave characteristics i.e. frequency, wavelength, direction and energy. In this context, fuzzy B-spline was utilized to reconstruct a global topographic structure between the data points, were used to support an approximation to the real successive tsunami wave propagation
