RA Code: A Robust and Aesthetic Code for Resolution-Constrained Applications.

Recently, some picture-embedding schemes have been proposed to improve the aesthetic appearance of 2D barcodes. However, these aesthetic 2D barcodes are not robust to the distortions incurred by the print/display-and-capture channel under limited rendering space and resolution. In this paper, a picture-embedding 2D barcode named the Robust and Aesthetic (RA) Code is proposed to counter the channel...
