Using the geometric pattern-matching algorithm with the gray rectangle pattern described earlier yields information about the rectangle’s edges, not about the gray-scale levels in the rectangle.

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 ...
