Abstract
A computer system and computerized method that groups documents with similar image layout together. A document similarity metric based on locally connected subgraphs is employed. Region adjacency graphs are generated from word segments extracted from document images. Fuzzy attributed graph isomorphism is performed on subgraphs checking node and edge attribute similarity. Document similarity is then calculated on a normalized score between matching subgraphs of different documents. Unsupervised clustering of document layouts is performed to generate clusters of documents with similar structure.
