How Folds Cut a Scene

  title={How Folds Cut a Scene},
  author={Patrick S. Huggins and Steven W. Zucker},
We consider the interactions between edges and intensity distributions in semi-open image neighborhoods surrounding them. Locally this amounts to a kind of figure-ground problem, and we analyze the case of smooth figures occluding arbitrary backgrounds. Techniques from differential topology permit a classification into what we call folds (the side of an edge from a smooth object) and cuts (the background). Intuitively, cuts arise when an arbitrary scene is “cut” from view by an occluder. The… CONTINUE READING
