Volume Rendering Effect Analysis with Image Preprocessing Technology Based on Three Dimension Anisotropic Diffusion

This paper mainly researches how to promote two-dimensional anisotropic diffusion into three-dimensional space, it deduces three dimension anisotropic diffusion formula and compares two-dimensional anisotropic diffusion with three-dimension one, and concludes that the three-dimensional anisotropic diffusion has better image smoothing effect.
