Neighbor Interpolation
To estimate of the missing color information at a pixel, this
algorithm simply uses the closest and left-uppermost
neighboring pixel (of the missing color) value. For example, for a pixel
containing only red information, we use the green value of the pixel
on its left to estimate the missing green value, and the blue value of
the pixel on its upper-left to estimate the missing blue value.
