Render Synthetic Objects with Background Image According to Image-Based Lighting

Image-based lighting (IBL) technique helps people integrate synthetic object into real-world environment. The general IBL method renders object using the captured omnidirectional high dynamic range (HDR) image as lighting condition. This paper extends the general IBL technique to employing single-view background image in HDR format to produce environment light. This idea is different from the general IBL technique which limits the input in omnidirectional light probe image. Besides, the proposed method can modify the background image slightly for special purpose based on texture transplanting. The created texture is saved in database; when people wish to modify the background image, they call texture from database and transfer it to the target surface. The method provided in this paper can produce visual effect just as real objects would.
