Firstly, with Gaussianizing filter being defined explicitly, a practical method on filtering performance evaluation is given. Secondly, two typical Gaussianizing filters are studied.

After implementation, mechanisms and performances of each filter are contrastively discussed, an example with lake trial is illustrated.
