Lowpass

Menu:   Processing > Filters… > Smooth > Lowpass

Script:   lowpass

Use this function to apply the lowpass filter to an image. The filter replaces the target pixel with the mean value in its neighborhood, thus eliminating high-frequency information. As a result, the image gets blurred and the noise suppressed. 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 square neighborhood in which the averaging will be performed. This value must not exceed 2*Overscan+1. See Preferences for more details.
