Abstract: 2D and 3D data of a scene are linked by associating points in the 3D data with corresponding points in multiple different 2D images within the 2D data. Labels assigned to points in either data can be propagated to the other data. Labels propagated to a point in the 3D data are aggregated, and the labels ranked highest are kept and propagated back to the 2D images. 3D data including labels produced in this manner allow partially obscured objects in certain views to be more accurately identified. Thus, an object can be manipulated in all 2D views of the 2D data in which the object is at least partially visible, in order to digitally remove, alter, or replace it.

Abstract: A one-way display system includes a transparent screen and a transparent color filter. An image is emitted by the screen or projected onto the screen. The image is formed from a combination of colored lights. Instead of spanning all the wavelengths of each color, each light only spans a narrow band of the color. The color filter removes the narrow band so the image is only visible from one side of the screen. As the color filter removes only the narrow band, one can still look out and see objects on the other side of the screen minus the colors of the narrow band.

Abstract: A one-way display system includes a partially reflective screen with a first image, and a partially absorptive screen with a second image that is an inverse of the first image. The two screens can be stacked on top of each other or separated by a small distance. A portion of ambient light on a first side of the display system passes through the partially reflective screen and exits as intermediate light. A portion of the intermediate light passes through the partially absorptive screen and exits as transmitted light to a second side of the display system. The transmitted light is spatially and chromatically uniform like the ambient light. This allows observers on the second side to see objects on the first side without the first image, and observers on the first side to see the first image.
