Disclosure document (101) is a classified communication document (102) or a non-communication document (104) by extracting (300) image information from a digitized image produced by a scanner (106). The image information is typically extracted after first applying a thresholding module (204) on the digitized image, and then applying a connected component processor (208) to the resulting binarized image. The character image information is compared (304) to stored image information. The stored image information may include criteria such as height, location, and density of the connected components within the image. Depending upon the results of the comparison, the document (101) is then classified (308) as either a communication document (102) or a non-communication document (104). If the document (101) is classified as a communication document (102), the subsequent pages are stored in the same file location as the recognized communication document (102). When a next communication document (102) is recognized, it is stored into a new file location, and its supporting documents (104) are then stored with it. Thus, in accordance with the present invention, a stack of documents (101) containing different communications may be inputted into a scanner (106), and the different communications are recognized and grouped together, without further involvement from the user (160).
