Abstract

Two-dimensional barcodes are widely used for encoding data in printed documents. In a number of applications, the visual appearance of the barcode constitutes a fundamental restriction. In this paper, we propose high capacity color image barcodes that encode data in an image while preserving its basic appearance. Our method aims at high embedding rates and sacrifices image fidelity in favor of embedding robustness in regions where these two goals conflict with each other. The method operates by utilizing cyan, magenta, and yellow printing channels with elongated dots whose orientations are modulated in order to encode the data. At the receiver, by using the complementary sensor channels to estimate the colorant channels, data is extracted in each individual colorant channel. In order to recover from errors introduced in the channel, error correction coding is employed. Our simulation and experimental results indicate that the proposed method can achieve high encoding rates while preserving the appearance of the base image.
