We label the demosaicking method [1] as ¡°SOLC¡±; the demosaicking method [2] as ¡°VNG¡±; the demosaicking method [3] as ¡°AHD¡±; the demosaicking method [4] as ¡°SAD¡±; the denoising method [5] as ¡°SOFT¡±; the denoising method [6] as ¡°PBSHRINK¡±; the denoising method [7] as ¡°MIXSCALE¡±; the joint demosaicking-denoising method in [8] as ¡°TLS¡± and the proposed joint demosaicking-denoising scheme as ¡°PROPOSED¡±.

 

With these labels, the color reproduction result by using the demosaicking method ¡°SOLC¡± and denoising method ¡°SOFT¡± of image fence is saved as ¡°fence_solc_soft.tif¡±, and so on.
