Theory of Operation

BinaryMorph Filter processes an input region by replacing each pixel with a function of its neighbors. The standard binary morph operations supported are:

• Erosion

• Weak erosion

• Shape erosion

• Noise erosion

• Dilation

• Weak dilation

• Shape dilation

• NOP (no operation)

In addition, you may specify a binary morph lookup table to map a source 3x3 pixel neighborhood to a result 3x3 neighborhood to achieve any binary morphology function desired.

The basic setup for BinaryMorph Filter is shown in Figure 13-1, and consists of parameter setup for threshold, number of iterations, morphology function, value of the border pixels, and polarity of the input image.

Note: When Training, modified pixels are not displayed within the image until a tool is placed within the BinaryMorph Filter step.
