             abstract = "The modeling of weathering effects in still images is a powerful 
                         editing tool for many graphics applications. Although most of 
                         these effects can be generated by manually creating textures 
                         through graphics editing applications, performing such artist work 
                         is time consuming. More sophisticated and automatic solutions to 
                         simulate a wide variety of weathering effects become essential. We 
                         present a method to generate and transfer weathering effects on 
                         images based on chroma distribution and luminance manipulation. 
                         Our solution has three main contributions over prior work. First, 
                         we propose an alternative solution to appearance manifolds, called 
                         appearance maps, to help synthesize variations in appearance in 
                         objects due to weathering effects. Although powerful, appearance 
                         manifolds are costly to build. The use of appearance maps allows 
                         real-time editing of images. Second, we extend the technique by 
                         using texture mapping ideas to allow the inclusion of weathering 
                         effects on images without them. Finally, we provide a mechanism to 
                         properly handle highlights, extending the range of possible images 
                         for manipulation. The results illustrate the flexibility of our 
                         solution and we also present results comparing real and virtual 
                         decay processes. Applications of this technique include virtual 
                         restorations of objects and images, as well simulation studies on 
                         future appearance of objects under environmental influence.",
