Detailed Description

Smoothes image and mixes the result with the original.

Example. With loops=2 and smooth mixing with coeff=c (instead of maximum), this operator produces

\[ F2 = (1-c)F + cM\{ (1-c)F + cM\{F\} \} = (1-c)F + (1-c)cM{F} + c^2M^2{F} \]

where $F$ is an image, $M\{\}$ is a FastAverage operator of size $W \times H$, and $c$ is the mixing coefficient between 0.0 and 1.0.

This operator can be also used for restoring images containing specks of low quality.
