Open
The Open module performs an erosion (shrinks the current white image), followed
by a dilation routine (grows the current white image). Erosion
followed by dilation will open objects closed by a thin boundary.
Interface
Instructions
1. Erode Count - Specify the number of times to perform erosion before dilation. Higher numbers will
open thicker objects.
2. Symmetrical - if you wish to erode and then dilate an unequal number of times (leaving the
resulting blob larger or smaller than the original) unselect the "Symmetrical" checkbox. This
will allow you to specify a different number of the Dilate Count.
3. Dilate Count - only active if module is not symmetrical meaning the image will be
eroded and then dilated an unequal number of times.
4. Restrict erosion - if using an asymmetrical opening you may want to restrict the
dilation process to NOT become larger than the original image. Selecting "Restrict erosion"
will ensure that the dilation part of the processing does not dilate parts beyond that of the original
blob.
