For resolution test of production process, a special pattern is inserted. The pattern is pre-defined but the location can vary. The pattern is composed of a few lines (rectagles with various but pre-defined dimensions) and a few characters drawn with rectangles.
How can a ruby script find the location of the pattern?

Hi,
the solution strongly depends on how the pattern is defined. Could you how a sample?

Below is the pattern. Line widths are 26, 28, ..., 35um.
I have a proposal:
The idea is take the biggest rectangle from the pattern, look for the same on the mask and with these candidates do a detailed analysis using an XOR.
This was my test pattern:
And this is where the script found it:
