Close

The Close module performs a dilation routine (grows the current white image), followed by an erosion (shrinks the current white image). Dilation followed by erosion will connect objects close to each other.

Interface

Instructions

1. Dilate Count - Specify the number of times to perform dilation before erosion. Higher numbers will connect more distant objects.

2. Symmetrical - if you wish to dilate and then erode an unequal number of times (leaving the resulting blob smaller or larger than the original) unselect the "Symmetrical" checkbox. This will allow you to specify a different number fo the Erode Count.

3. Erode Count - only active if module is not symmetrical meaning the image will be dilated and then eroded an unequal number of times.

4. Restrict erosian - if using an asymmetrical closing you may want to restrict the eroding process to NOT erode more than the original image. Selecting "Restrict erosian" will ensure that the eroding part of the prorcessing does not erode parts of the original blob.
