Claim 0:
1. A method for visual recognition, comprising:
receiving an output of an optical character recognition process comprising a recognized block, the recognized block comprising a set of positional properties and recognized text;
creating a block weight from the set of positional properties for the recognized block;
creating a set of block tri-character grams for the recognized block based on the recognized text for the recognized block;
creating a block tri-character gram feature vector based on the set of block tri-character grams;
creating a block feature vector for the recognized block from the block weight and the block tri-character gram feature vector for the recognized block;
creating a feature vector based on the block feature vector;
retrieving a set of results from an index, wherein the index includes entries for documents, and further wherein the set of results is retrieved based on the feature vector; and
submitting the feature vector to a trained machine classifier,
wherein retrieving the set of results from the index based on the feature vector occurs responsive to the trained machine classifier classifying the feature vector into a designated category.
