Comparisons Between Bgi And Wiener Filter Method In Resolution Enhancement Of Simulated Image
GEO Satellite imagery is an important tool and can be used to estimate rainfall during the thunderstorms and
hurricanes for flash flood warnings in real time. However, for the GEO satellite is located higher than normal LEO satellite,
the spatial resolution images are lower. Therefore, in order to obtain an image with enough resolution, some methods are to
be implemented in GEO satellite observation, such as resolution enhancement which is a technique that achieves higher
resolution for satellite image with lower resolution? This paper focuses on the comparative between two techniques that are
used to increase resolution of the images. Wiener filter and Backus–Gilbert inversion (BGI) technique, the two algorithms
are compared via both the simulation. The theory of BGI and Wiener filter method are described. The simulation is
introduced, and the results are discussed.
