Auto Contour

Auto contour creates closed contours that belong to the current object. The contours surround areas that are either above or below a selected threshold.

To start using it, switch to High Contrast to see what areas fall above or below threshold. Adjust the threshold to the proper level to segment your features of interest, switching back and forth between Regular and High contrast as needed. Select the Alternate mouse to use the mouse buttons to control the filling operation. Then click on the interior of a desired area to flood that area in red. Adjust the area if necessary then press the Build button or the b hot key to build a contour around the area.
