Anisotropic vector diffusion in image smoothing
Zeyun Yu, Chandrajit Bajaj · Proceedings - International Conference on Image Processing · 2003
Anisotropic diffusion has been widely used in image processing for its efficiency of smoothing the noisy images while preserving the sharp edges. In this paper we explore a general version of anisotropic diffusion schemes for vector-valued images, based on the polar-coordinate representation of the vectors. As an example, we apply our method to color images and show its ability of edge-preserving smoothing on vector-valued images.
