| Abstract(in English) | The authors study to recognize water's behaviors by computer vision approach and reproduce the recognized behaviors using Bump Mapping in a virtual environment. To reproduce the shape of water's surfaces, it's necessary to estimate the orientations of surface normals to the surface. For this, we proposed to utilize Shape from Shading. However, since Shape from Shading assumes orthographic projection for the camera projection model, large estimation errors appear in pixels apart from the optical axis of the camera. To improve the estimation accuracy, one idea is to check the combination of all the possible surface normal's orientations, but this causes combinatorial explosion. This paper proposes a genetic algorithm based method for suppressing the errors efficiently, Experimental results using synthetic images show the effectiveness of the proposed method |
