1. Multi resolution Texture Synthesis on Surfaces Arul Prakash Lavanya Tekumalla

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.

3. 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 samples
