Developers of machine-vision systems face a significant challenge: Their systems must accurately locate reference patterns that may appear different from one product to the next. For many years, ...

An algorithm, which determines the range of a preceding vehicle by a single image, had been proposed. It uses a "Range-Window Algorithm". Here in order to realize higher robustness and stability, the ...

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 ...
