Script:   gauss

Use this function to apply the discrete Gaussian filter to an image. The filter's kernel is based on the discrete approximation of the isotropic 2D Gaussian distribution:

The effect is similar to the one of the Lowpass filter, but it degrades the image less while reducing the noise. If you choose this command, the following options will become available:

Input

Displays the input image frame number. If you want to process another image, type or select the corresponding value.

Output

Displays the number of the frame in which the output image will be created. Depending on the Preferences. ImageWarp will set it either to the first available value or to the Input frame number. Type or select another value if you want the output image to be created in a different frame.

Preview

Select this check box to watch the Preview of the output image.

Size

Lets you choose the size of the Gaussian kernel. This value determines the standard deviation (sigma) of the Gaussian distribution, so that the kernel is effectively truncated at the point of three sigma. The Size must not exceed 2*Overscan+1. See Preferences for more details.
