Elliptical Filter
The Elliptical Filter applies an equal weight elliptical filter to an image. The filter may have circular symmetry or be elongated and rotated. The Gaussian Filter is similar in these regards but uses Gaussian weights rather than equal weights. The Rectangle Filter is similar but has uniform weights over a rectangle rather than an ellipse.
This command opens from the Process > Filters menu.
Properties of the Elliptical Filter
|
Profile Selects the parameter profile for this command. |
|
|
[Select] |
Selects the source images from an image window, folder, files, pattern, or a file list. |
|
Width |
Specifies the width in pixels of the elliptical filter if circular or the width along the major axis if the filter is elongated. |
|
|
Specifies whether the elliptical 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 Elliptical 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. |
