Smooth Object Boundaries in Binary Images

1. Click Binary»Basic Morphology or select Basic Morphology in the Binary tab of the Processing Functions palette.
2. Select a function from the Basic Morphology list. You can use one of three morphological functions to smooth the boundaries of objects:
   • Proper Open—Smoothes boundaries of objects and fills small holes.
   • Proper Close—Smoothes boundaries of objects and removes small particles.
   • Auto Median—Smoothes boundaries of objects.
3. Set the Size of the Structuring Element.
4. Click the cells of the structuring element that you want to have a value of 0.
5. Click OK to apply the smoothing function and add this step to the script.

Note  The structuring element is a 2D array used as a binary mask. You can modify the structuring element by clicking its cells. If a cell is black, it has a value of 1. If a cell is white (empty), it has a value of 0.

Tip  Experiment with different coefficients and the Kernel Size to get the results you want.
