The present study proposes a method to extract and apply biological properties to naturally realize a scar texture on the skin. The ratio of melanin to hemoglobin in the skin, which determines inter- and intra-individual variations in skin appearance, is extracted as a biological property. First, a color table is defined using parameterized biological properties. Using an inverse-lighting equation that we define, biological parameters and rendering parameters are extracted from a single obtained or downloaded scar image without taking a picture of a scar directly. The extracted parameters are used to realize the most appropriate scar on the actual skin. To express the geometric depth of the scar, a tessellation process is employed. Finally, we provide the experimental results from the evaluation of our method.
