- Note, for example, how the glass bottle in the primal image (a) appears as the caustic in the dual image (b) and vice-versa. Because we have determined the complete light transport between the projector and camera, it is easy to relight the dual image using a synthetic light source (c) or a light modified by a matte captured later by the same ...

- A novel photographic technique called dual photography is presented, which exploits Helmholtz reciprocity to interchange the lights and cameras in a scene, and is fundamentally a more efficient way to capture such a 6D dataset than a system based on multiple projectors and one camera. We present a novel photographic technique called dual photography, which exploits Helmholtz …

- Abstract. We present a novel photographic technique called dual photography, which exploits Helmholtz reciprocity to interchange the lights and cameras in a scene. With a video projector providing structured illumination, reciprocity permits us to generate pictures from the viewpoint of the projector, even though no camera was present at that ...

- Dualphotography. Dualphotography is the photography technique of simultaneously taking two photographs of one scene, thus capturing a scene from both sides of the photographic device at once. In other words, it is the practice of creating a photographic scene from two opposing or complementary sides of a single real-world situation.

- The accurate measurement of the light transport characteristics of a complex scene is an important goal in computer graphics and has applications in relighting and dual photography. However, since the light transport data sets are typically very large, much of the previous research has focused on adaptive algorithms that capture them efficiently.

The objects are seen from the front in the dual image, while the camera sees them from the side. (c) Dual photography is able to capture details not visible in the ...
