We present a method to automatically construct features capable of putting images in correspondence with each other (i.e., registration) without requiring control points or landmarks on the images in question. Our method is based primarily on Principal Component Analysis (PCA) and a suitable image representation. The feature set is a collection of weight vectors and the correspondence mapping i...

harmony and disharmony are generally considered in isolation in the phonological literature. this has led to a striking asymmetry in their analyses. in this article, it is argued that both phenomena call for a parallel treatment and that this can be accomplished within correspondence theory.correspondence theory provides a general framework for defining faithfulness constraints. what happens in...
