Automatic storage, retrieval and visualization of bank check images

This paper presents an automated system for storage and retrieval of bank checks in contrast with the microfilming techniques that are currently used. The bank check images are introduced into an extraction module where the filled in information is segmented. This information is indexed via keywords derived from the MICR line and stored in a database under a hybrid structure where hash tables, trees and inverted files are employed. For the information retrieval and visualization, make-up bank check images are generated. The experimental results reveal a good performance of the proposed method in terms of compactness of stored information and high visual quality of the reconstructed images
