Detailed Description

This functor makes a color interpolation of common BAYER Patterns used in digital cameras.

Member Enumeration Documentation

enum lti::bayerDemosaicing::eBayerMethod

Enumeration of supported interpolation methods.

Enumerator:

Simple	Do averaging of two green values per pixel.
NearestNeighbor	Take the nearest (vertical) green value for each pixel.

enum lti::bayerDemosaicing::eBayerPattern

In a Bayer pattern there are three different color filters used in front of the actual pixels of the CCD chip.

They have the colors red(R), green(G), and blue(B). On a 2x2 grid of pixels two are always green and these always lie on a diagonal. This results in four possible constellations for the three colors.

If NoBayer is chosen then no demosaicing takes place. This makes sense for mono cameras or to avoid demosaicing.

Enumerator:

NoBayer	no Bayer pattern used, no demosaicing, mono camera
RGGB	Red, Green in first row, Green, Blue in second.
BGGR	Blue, Green in first row, Green, Red in second.
GBRG	Green, Blue in first row, Red, Green in second.
GRBG	Green, Red in first row, Blue, Green in second.
