smooth - gaussian image smoothing

  smooth[/qualifiers]

Gaussian smoothing of current image. The gaussian width can be specified with qualifier sigma. If sigma is not specified a default value of 1.5 pixels is used.

smooth/exposure_map

Smooth the exposure map.

smooth/sigma=n

To enter the user defined value of sigma for the Gaussian smoothing

smooth/scaling_factor=x

Enter a Scaling factor.

smooth/x_only

The smoothing is applied only in the x direction.

smooth/y_only

The smoothing is applied only in the y direction.

smooth/gaussin

A gaussian function is used in the smoothing. ThIs is the default function used.

smooth/wavelet

A wavelet function is used in the smoothing.

Examples:

smooth/sigma=2.         ! Smooth the current image using a gaussian filter with
                        ! sigma equal to 2 image pixels.
