Abstract
A 3-D effect is added to a single image by adding depth to the single image. Depth can be added to the single image by selecting an arbitrary region or a number of pixels. A user interface simultaneously displays the single image and novel views of the single original image taken from virtual camera positions rotated relative to the original field of view. Depths given to the original image allow pixels to be reprojected onto the novel views to allow the user to observe the depth changes as they are being added. Functions are provided to edit gaps or voids generated in the process of adding depth to the single image. The gaps occur because of depth discontinuities between regions to which depth has been added and the voids are due to the uncovering of previously occluded surfaces in the original image.
