Demosaicking algorithm for the Fujifilm X-Trans color filter array

Digital cameras reconstruct a full color image using the information captured by different color sensors (RGB) through a Color Filter Array (CFA). A demosaicking algorithm uses the information of the CFA data to restore a full color array. Demosaicking algorithms reconstruct two unknown color components for a pixel at each spatial location. During this stage, the values of other components will be measured mostly by neighboring pixels´ information. Since the Fujifilm X-Trans pattern is one of the more successful CFAs, we attempt to model the demosaicking steps using this pattern and simulate both non-adaptive and adaptive demosaicking schemes. Kodak sample images are used in order to validate and compare different approaches with related previous work.
