Figure 1. Geometric pattern-matching tools let users set up a target for use in a machine-vision system. The software trains itself to handle any pattern, and it can create test suites that help it ...

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 ...

We describe a new algorithm for matching star lists, given by their two-dimensional coordinates. Such matching should be unaffected by translation, rotation, rescaling, random perturbations, and some ...

“It is also insensitive to changes in lighting conditions, which is a common occurrence in real-world situations,” notes Zadeh, who developed the geometric pattern-matching (GPM) algorithm for his ...
