  25. 25. 13<br />b) Other Tweaks<br /><ul><li>Perspective Transformation</li></ul>IeWhen 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.<br /><ul><li>Interpolatation</li></ul>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.<br />
