Table 3.

The PSNR values (dB) of each channel (R, G, B) and CPSNRs of the whole image (RGB) of 9 demosaicking algorithms on Kodak, McMaster, Urban100, Manga109 datasets and the final average values of them. The bolded two methods in each section are those that achieve better performance among all algorithms.
