Graph lattice method for image clustering, classification, and repeated structure finding

摘要

A document recognition system and method, where images are represented as a collection of primitive features whose spatial relations are represented as a graph. Useful subsets of all the possible subgraphs representing different portions of images are represented over a corpus of many images. The data structure is a lattice of subgraphs, and algorithms are provided as means to build and use the graph lattice efficiently and effectively.
