Table 2 Comparison of modelling luminance + chromaticity and RGB

		Mean	Median	Mean bottom quartile	Mean top quartile
Lum + Chrom (16D + 9D ×2)	PTM	32.60	32.80	28.58	36.37
	HSH	31.80	32.86	24.67	36.51
RGB (11D ×3)	PTM	30.35	30.49	25.71	34.20
	HSH	30.33	31.28	23.68	34.95
RBF	47.94	46.47	36.60	61.63

PSNR statistics for PTM and HSH, using LS + regularization, for dimensionalities 16 and 9 for luminance and chromaticity and similarly for modelling R,G,B separately with 11D each. For completeness, we also show values for RBF modelling.
