Motivation |
| Biomedical images are often corrupted by a large amount of noise which makes their analysis difficult. Smoothing is an accepted methodology to reduce the effect of noise. However, normal smoothing blurs the bounderies, particulary in images containing fine structures. Hence, in this project we attempt to perform anisotropic smoothing that preserves the bounderies while reducing the noise. |
| Approaches |
| Different methods have been implemented: the Edge Enhancing Diffusion, the Ridge Enhancing Diffusion and the Spatial Coring. |
