Self-similarity Based Editing of 3D Surface Texture s

摘要: This paper presents inexpensive methods for selfsimilarity based editing of real-world 3D surface textures. Unlike self-similarity 2D texture e diting approaches which only make changes to pixel color o r intensity values, these techniques also allow surfa ce geometry, reflectance and other representations the captured textures be edited relit using illumination directions that differ from thos original. A single operation at a given location affects all similar areas produces cha nges on images sample rendered under differen t conditions. We perform painting, cloning warpin g operations over two sets representations: (1) height albedo maps , (2) eigen base images. The are commonly used bump mapping, can representing with complex reflectance. res ult efficiently in modern computer graphics packages real-time applicatio ns as rendering process requires simple calculations such weighted sums
