FA maps of the denoising results for real datasets. The first and second rows are the denoising results for DTI datasets with b values of 1931 and 3091 respectively. The column a and b are the original fractional anisotropy maps and the denoised maps. The column c and d are the original and denoised color fractional anisotropy maps
