The synthesis of weathering using multi-label map

Texture synthesis has been researched for several decades, and a good texture can improve the quality of 3D objects. However, it is very difficult to obtain good textures through realistic scenes or the process of time-varying weathering. This paper introduces a method using a label map to control texture synthesis. The labels, which are extracted from source images, represent the different degrees of weathering in an image, meaning this method can synthesize a new label map that controls the region of weathering, while preserving the boundary feature. Furthermore, we can synthesize a more or less weathered texture from the source texture by image analogy.
