Frequency-domain methods for demosaicking of Bayer-sampled color images

Frequency-domain methods for demosaicking of Bayer-sampled color images

This letter presents a new and simplified derivation of the frequency-domain representation of color images sampled with the Bayer color filter array. Two new demosaicking algorithms based on the frequency-domain representation are described and shown to give excellent results.
