Diagonal versus affine transformations for color correction.
Standard methods for color correction involve the use of a diagonal-matrix transformation. Zaidi proposes the use of a two-parameter affine model; we show that this offers no improvement in terms of accuracy over the diagonal model, especially if a sharpening transformation is also used.
