3D models are often lacking a photorealistic appearance, due to low quality of the acquired texture, or to the complete absence of it. Moreover, especially in case of reality based models, it is often of specific interest to texture with images different from photos, like multispectral/multimodal views (InfraRed, X-rays, UV fluorescence etc), or images taken in different moments in time. In this work, a fully automatic approach for texture mapping is proposed. The method relies on the automatic extraction from the model geometry of appropriate depth maps, in form of images, whose pixels maintain an exact correspondence with vertices of the 3D model. A multiresolution method is here proposed to speed up the automatic texturing phase. Maximization of Mutual Information (MMI) is used as similarity measure as it proved to optimally exploit shared information, discarding unrelated features. 3D texturing is then applied to the portion of the model which is visualized in the texture.
