A method for Golden Template Comparison (GTC) is provided that can be used to efficiently perform flaw and defect detection on a two-dimensional test image that is at least rotated and/or scaled and/or sub-pixel translated. Run-time inspection speed and accuracy is substantially improved by retreiving...http://www.google.com.au/patents/US5850466?utm_source=gb-gplus-sharePatent US5850466 - Golden template comparison for rotated and/or scaled images
