Interactive Image Based Relighting with Physical Light Acquisition

We present an interactive image-based technique to relight real scene with physical light sources acquisition. Firstly, basis images of the real scene are acquired from a fixed viewpoint. Secondly, light direction is estimated and physical light image is captured. Thirdly, measurement image between the reference light image and the novel light image is computed for relighting scene. We demonstrate the technique by interactively relighting a pre-captured real scene using a hand held spotlight projecting light on a white paper. Key words: Interactive, Image-based Relighting, Physical Light Acquisition, Lighting Sensitive Display
