2-D Polygon Finder Settings

Use 2D Polygon Finder to create polygons after you correct and filter the image data. This tool maps areas of equal intensity and attempts to create a polygon to surround each feature in a 2D section. You can view these polygons on the Image window and verify that they are correct. You can also access the polygons with the Edit Polygon, Cut Mask and 3D Object Builder tools, or save them to a file that can be read by any of these tools.

Open 2D Polygon Finder by choosing Model | 2D Polygon Finder on the main softWoRx menu.  

Use

To...

Window, Select region, Reset, Details,

Wavelengths

Specify input data and output parameters as shown in Image Input and Output.

Border Width

Specify a border area around the image. If preprocessing (such as filtering) has created a noisy border around the image, you can specify how much of that area to ignore.

Polygon Smoothing

Specify the optimal number of pixels between polygon points. The 2D Polygon Finder samples more finely in areas of greater detail.

Minimum Perimeter

Specify the minimum number of points for a polygon. Any polygons with fewer points than the Minimum Perimeter are excluded.

Maximum Perimeter

Specify the maximum number of points for a polygon. Any polygons with more points than the Maximum Perimeter are excluded.

Exclude Edge Objects

Exclude polygons that touch the edge of the image.

Outer Objects Only

Find only the outer-most continuous polygons. When this option is unselected, polygons that are fully contained within others are created (if detected).

Threshold

Specify the intensity value to follow to identify features.

Number of Polygons

Display the total number of polygons in all Z sections.

Polygon Statistics

Display a table of statistical values.  

Polygon Editor

Start the Polygon Editor to modify the polygons in the selected window.

3D Object Builder

Launch the 3D Object Builder to associate the 2D Polygons into 3D Objects (after polygons are created on 2D sections).

Save Polygon File

Provide a file name for the polygon list and save it.
