Abstract :
A simple but effective multiframe demosaicking method is proposed. It is compared to a multiframe noise reduction of similar complexity. The comparison was based on computer-based simulation of a shaking camera. MSE, PSNR and NCD errors measurements were taken. Further ways of enhancing the algorithm without significant increase in complexity are proposed. The described multiframe demosaicking algorithm is suitable for mass production devices such as mobile phones of digital cameras. Its primary goal is to replace more expensive mechanical motion compensation systems.
