I would like to explain the supported modes in the guided filter,
(1) Basic mode shows better denoising performance compared to bilateral
filter and can be applied in many applications such as detail enhancement,
dehazing, and so on, which is illustrated in paper
http://kaiminghe.com/eccv10/.

Additionally so called fast mode, which is indeed faster than bilateral
filter, is
Why this filter is being applied at first place at all?
It is extraordinary slow and used very slow algorithm and reallocates
memory all the time.

Enhanced guided filter and fast enhanced guided filter are supported.
The enhanced guided filter can better preserve edges for denoising tasks.
And the box filter operation is optimized.
