Abstract
A method for demosaicing a raw image includes: (1) horizontally-interpolating a green channel formed of primary pixel-values B(x,y)to yield a horizontally-interpolated green channel that includes both B(x,y)and non-primary pixel-values I(x,y); (2) modifying each I(x,y), by horizontally-neighboring pixel-values, to yield a refined horizontally-interpolated green channel; (3) vertically-interpolating the green channel to yield a vertically-interpolated green channel that includes pixel-values I(x,y); (4) modifying each I(x,y)by vertically-neighboring pixel-values, to yield a refined vertically-interpolated green channel; (5) generating a full-resolution green channel from the refined interpolated green channels and gradients thereof; (6) generating a full-resolution red channel by determining red pixel-values from a local-red mean value of neighboring pixel-values and the full-resolution green channel; (7) generating a full-resolution blue channel by determining pixel-values from a local-blue mean value of neighboring pixel-values and the full-resolution green channel; and (8) combining the full-resolution channels to yield a demosaiced raw image.
