Image-Guided Weathering: A New Approach Applied to Flow Phenomena - Supplementary Material

This document contains additional material for the paper ”Image-Guided Weathering: A New Approach Applied to Flow Phenomena”. This material consists of a set of maps and parameters obtained for different stain exemplars. For each exemplar, the following maps are shown: the input stain image, the extracted degree map, the simulated stain after fitting the parameters, the synthesized detail map, and the non-linear color function. The fitted parameters for all the exemplars are included in Table 1 for reference. Figures 1 to Figure 3 first show results for stains fitted without using our flow deflection model. In Figure 3, the fittings were done using multiple stains at the same time. Two groups of stains are shown, one corresponding to three efflorescence stains (top) and another corresponding to two mold stains (bottom). As each group of stains belongs to the same surface and stain material, the stains were fitted using shared parameters for both the target surface and the stain material. Figures 4 to Figure 7 show results for stains fitted using our flow deflection model. Finally, Figure 8 shows exemplars of stains on more complex target objects, where non-flat proxies are used to approximate the targets during the fitting.
