It is also known as CFA interpolation or color … See more The aim of a demosaicing algorithm is to reconstruct a full color image (i.e. a full set of color triples) from the spatially undersampled color channels output from the CFA. The algorithm should have the following traits: See more A color filter array is a mosaic of color filters in front of the image sensor. Commercially, the most commonly used CFA configuration … See more Simple interpolation These algorithms are examples of multivariate interpolation on a uniform grid, using relatively straightforward mathematical operations on nearby instances of the same color component. The simplest … See more • Bayer filter See more To reconstruct a full color image from the data collected by the color filtering array, a form of interpolation is needed to fill in the blanks. The mathematics here is subject to individual implementation, and is called demosaicing.
