For many years, developers chose mathematical-correlation algorithms for most pattern-matching applications—a technique that still works well, as long as you can adapt your inspection system to its ...

For determining the model shape and model deformation in wind tunnels or wing deformation in flight tests, Image Pattern Correlation Technique (IPCT) is applied. This technique utilizes photogrammetry ...

2. We describe a novel technique for identifying individual whale sharks Rhincodon typus through numerical pattern matching of their natural surface 'spot' colourations. Together with scarring and ...
