Back-compatible Color QR Codes for colorimetric applications

作者：

Highlights：

• Color correction often relies on color charts that can accomodate limited colors (10 s).

• QR Codes can be used to accomodate a large number of color samples (1000 s).

• QR Code have compact form factor (a few inches) while chart have a wide factor form.

• Our grayscale affinity to black and white during color mapping is fully back-compatible.

• Grayscale method leads to much higher readability in adversarial opticial conditions.
