Edit Segment

The "Edit Segment" tool allows users to modify a segmented region using a paintbrush or eraser, providing a detailed and customized approach to segmentation editing.

Steps

1. Select a Segment

   • Select the segment you want to edit and click the "Edit Segment" tool.

2. Paint

   • The following are the various options available for painting purposes:
     • Brush Shape: Circle, Square, and Lasso are the main types of brush shapes you can choose from.
     • Brush Size: This option is used to change the diameter (e.g., Circle) or area (e.g., Square) for a brush shape. It is not available for Lasso.
     • Edit in 3D: If enabled, it will allow editing in the 3D view. For Lasso, it is enabled by default.
     • Sphere Brush: This option is only available for the Circle brush shape. If enabled, a 3D spherical brush is used rather than a 2D circular brush.
     • Threshold Intensity: Enable or disable threshold intensity for segment editing. If enabled, a Threshold Intensity slider will be available to choose the intensity range.
   • To paint, place the mouse cursor inside the 2D or 3D view, hold down the left mouse button, and move the cursor.
     
     

3. Erase

   • Switch the tab from "Paint" to "Erase". All the other options remain the same and will be used for erasing purposes.
   • To erase, place the mouse cursor inside the 2D or 3D view, hold down the left mouse button, and move the cursor.
