The SRMS and means of differences between the estimated orientations before and after adding white Gaussian noise with SNR=0db. The textures D19, D22, D56, D76 and D102 have higher errors compared with other directional textures due to either multiple principal directions or weak staight lines that are significantly affected by the additive noise.
