A novel approach for audible acoustic quick response codes
Scientific Reports, 2022 Compared to image-based quick response (QR) codes, acoustic QR codes have some advantages. However, an acoustic QR scanner cannot recognize an acoustic QR code at a distance of more than two meters from an acoustic QR announcer. To this end, we propose a

Improving readability by modifying graphic QR code microstructure
Electronics Letters, 2021 White modules of quick response codes (QR codes) are degraded by dot gain, especially when printed at smaller sizes, which results in more false blacks than false whites in error analysis, and also severely affects decoding ability.
