Abstract

Each pixel in a full-colour image has three colour values, and warping of the colour image requires three times the computational load of a greyscale image. A new colour image warping is proposed for enhancing computational efficiency in real-time video applications. Considering that a colour filter array (CFA) is commonly utilised in an image sensor, the raw CFA image obtained from the image sensor is warped before colour reconstruction. The computational load is only one third of the conventional colour image warping.
