Algebraic projective geometry, with its multilinear relations and its embedding into Grassmann-Cayley algebra, has become the basic representation of multiple view geometry, resulting in deep insights into the algebraic structure of geometric relations, as well as in efficient and versatile algorithms for computer vision and image analysis.
Wherever you go in the English-speaking world, there are linguistic riches from times past awaiting rediscovery. All you have to do is choose a location, find some old documents, and dig a little.
