Printed Color Document Storage and Retrieval for Image Databases
Abstract:This paper describes a computationally efficient storage and retrieval method for the (R,G,B) color images of the printed documents. The proposed method is developed based on the principal component analysis of image color distribution. A new similarity measure is introduced for image retrieval based on the Tanimoto measure of recognizing similar patterns. This similarity measure is computationally effective since the vector inner product is the only operation needed for its computation.
Several feature sets are experimented in the computer simulation of the algorithm to demonstrate the efficacy of the image retrieval. It is determined experimentally that the proposed method is not affected by substantial changes in the databases. This is due to the fact that the features used for document retrieval are not predefined sets. Rather, they are extracted directly from the document images submitted for recording or searching. This makes the algorithm very robust and attractive for many applications of the image storage and retrieval systems.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
