2. Multi resolution Texture synthesis Build image/mesh pyramid. Assign color to each pixel/vertex by doing a neighborhood search in the texture image. Neighborhood search: very expensive TSVQ: Accelerates the search process by considering neighborhoods as points in a multi dimensional space and casting the neighborhood search process as a nearest point searching problem in a multi- dimensional space.

5. Texture synthesis on surfaces Retiling –Sprinkle some new vertices onto the mesh –Space them uniformly over the mesh using point repulsion. –Remove old vertices and re-triangulate –Create a hierarchy of meshes Neighborhood Construction: –flatten a set of nearby vertices –resample the flattened patch
