A texture-mapping scheme for volumetric models

In this article, we propose a texture-mapping procedure to enhance visual appearances of volumetric models. To texture a volumetric model, the proposed method performs an unsupervised training to transform a Self-Organizing Map (SOM) into a fitting surface at first. Then, another unsupervised training is conducted to UV-parameterize the fitting surface. As a result, a bridge connecting the volumetric model’s surface and the texture map has been established. In the following steps, filtering comp
