Gaussian Filter
The Gaussian Filter applies a Gaussian-weighted filter to an image. The filter may have circular symmetry or be elongated and rotated. The Elliptical Filter is similar in these regards but uses uniform weights rather than Gaussian weights.
The Gaussian Filter command opens from
the Image Window > Process >
Filters menu and 
button
on the Main Toolbar. The "immediate"
form, shown first, opens when an image or image set is displayed in
the top-most window. The general form can be used to select source
images from folders, windows, or by matching templates.

Profile [|>] |
Selects the parameter profile for this command and allows you to save or work with existing presets. |
|
[Select] |
Opens the Select Source Images dialog to choose images from an image window, folder, files, pattern, or a file list. |
|
Sigma |
Specifies the width of the Gaussian filter in terms of the Gaussian sigma. For example, Sigma=3 creates a filter width sigma value equal to 3.0. |
|
Symmetric |
Specifies whether the Gaussian filter is circularly symmetric. If checked, then a circular filter kernel is created with Elongation equal to 0. |
|
Elong % |
Specifies the percent elongation of the filter. This property applies only if Symmetric is not checked. |
|
Angle |
Specifies the angle in degrees of the major axis of the Gaussian kernel. This property applies only if Symmetric is not checked. |
|
Source Region |
Specifies the rectangular region to be processed. The options are as follows: Entire image: The entire image is processed. Image Cursor: The region to be processed is selected using the Image Cursor. Rectangle: The region specified by Min and Max limits for Column and Row coordinates is processed. Column and Row, Min and Max: When Rectangle is selected, these values specify the column and row limits to be processed. |
