We have seen in Chapter 3 that image sensors measure light intensity but
not its wavelength, and that in order to capture colors the most common
configuration is to use a single sensor covered with a mosaic color filter called
Color Filter Array (CFA). By far the most popular CFA is the Bayer pattern,
