Fig. 6From: Noise reduction of diffusion tensor images by sparse representation and dictionary learningFA 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 mapsBack to article page
