We label
the demosaicking method [1] as ¡°solc¡±;
the demosaicking method [2] as ¡°ahd¡±;
the demosaicking method [3] as ¡°sad¡±;
the demosaicking method [4] as ¡°dlmmse¡±;
the denoising method [5] as ¡°pbshrink¡±;
the denoising method [6] as ¡°mixscale¡±;
the joint demosaicking-denoising method in [7] as ¡°jdmdn_Hirakawa¡±;
the joint demosaicking-denoising method in [8] as ¡°jdmdn_Zhang¡±;
and the proposed PCA-based direct CFA image denoising scheme as ¡°pcadn¡±.
With these labels,
the color reproduction result by using the demosaicking method ¡°solc¡± and denoising method ¡°pbshrink¡± of image fence is saved as ¡°fence_solc_pbshrink.tif¡±, and so on;
the color reproduction result by using the joint demosaicking-denoising method ¡°jdmdn_Zhang¡± of image fence is saved as ¡°fence_jdmdn_Zhang.tif¡±, and so on;
the color reproduction result by using the proposed CFA denoising method ¡°pcadn¡± and demosaicking method ¡°solc¡± of image fence is saved as ¡°fence_pcadn_solc.tif¡±, and so on.
