Abstract

Since the data storage capacity per unit area of a QR code is very limited, it is restricted in various QR code applications. In this work, we propose an approach based on visual skew to improve the data capacity of the QR code. Our method can enhance the capacity of the QR code per unit area by using different angle views to combine several QR codes together. The storage capacity of the proposed mechanism can be increased by 1.5 times per unit area more than that of the normal QR-code.
