A High Capacity Color Barcode framework is proposed by exploiting the spectral diversity afforded by the Cyan; Magenta and yellow print colorant channels and the complimentary Red, Green and Blue channels, respectively, used for capturing color images. Here a three-fold increase in the data rate is achieved by encoding independent data in the C, M, and Y print colorant channels and decoding the data from the complimentary R, G, and B channels captured via a mobile phone camera. To mitigate the effect of cross-channel interference among the print colorant and capture color channel, Expectation Maximization Type Algorithm is used that estimates the parameters from regions encoding the data itself.
