Gallery of Separation Results |
Here, we show several examples of our separation results. In each case, we mention the separation method we have used. In all cases, the scene image is the sum of the computed direct and global images. However, to bring out the details, for some of the scenes we have brightened the direct and global images by a scale factor (between 1 and 2) with respect to the scene image. By clicking on each of the thumbnail images shown below, you can see the corresponding high resolution image.

| This scene of a building corner lit by the sun is scanned using a stick occluder. Notice the sharp shadows cast by the sun in the direct image. The global component on the other hand captures interreflections between the walls as well as the illumination received from the sky. |

| This curtain with folds was illuminated by a halogen lamp and scanned using a mesh occluder. The global image includes interreflections within the folds as well as translucency effects due to the fine spaces between the weaves of the fabric. |

| In this scene, a mannequin is placed just behind a translucent shower curtain. The mannequin is not directly lit by the source but by the light diffused through the shower curtain. The direct image only includes reflections from the shower curtain and not the mannequin. The global component reveals the mannequin behind the curtain. |

Global |
| This scene of red leaves is lit by the sun and is scanned using a thin stick occluder. The direct image has sharp and dark shadows. The global image, on the other hand, has a glowing effect due to the diffusion of light through the translucent leaves. It also includes the illumination of the leaves by the sky and surrounding buildings. Note that the green leaf beneath the red leaves (in the shadow area) does not receive any direct illumination from the sun and hence is visible only in the global image. |
