How Do I Mask a Template for Pattern Matching?

Primary Software: Vision Development Module
Primary Software Version: 8.6
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I know that Vision Development Module 8.6 has a new feature that allows me to mask a template for pattern matching. How do I do this?

Solution:
Masking a template can be very useful in situations where you want to ignore parts of your template. There are a couple of ways to mask a template.
  • Create a template in Template Editor (Start»All Programs»National Instruments»Vision»Template Editor) and select the Define Pattern Matching Mask tab.

    Note: Please reference the Online Help from the Help Menu for additional configuration information.



  • Create a template in Vision Assistant or Vision Builder for Automated Inspection 3.6 using the Match Pattern step. After defining your template area, select Next and define the mask. 

Note: You can only mask 8-bit grayscale templates.
