b) Other Tweaks

Perspective Transformation

Ie When we acquire QR code image, the plane in which camera lies may not be parallel to QR image which result in foreshortening effect. Then perspective transformation can be adopted.

Interpolatation

In the mathematical field of numerical analysis, interpolation is a method of constructing new data points within the range of a discrete set of known data points.
