ABSTRACT

In this study, we want to composite the source image and the target image when the environment includes water surface in the target image such as lake, sea, etc. The water surface is different from other common environment. On the water surface, the object must be reflected or refract and sometimes is deformed by the wave of water. In order to composite the object in the source image onto the water image, we analyze the water surface of the target image and let the object be synthesized realistically based on the wave of water. Our composite process consists of three steps. First, we use Shape-from-Shading technique to extract the　normal　vector　of the water surface in the target image. Next, the source image is deformed according to the normal　vector map. Finally, we composite the deformed object onto the target image.
