Depth maps are generated from a monoscopic source images and asymmetrically smoothed to a near-saturation level. Each depth map contains depth values focused on edges of local regions in the source image. Each edge is defined by a predetermined image parameter having an estimated value exceeding a predefined threshold. The depth values are based on the corresponding estimated values of the image parameter. The depth map is used to process the source image by a depth image based rendering algorithm to create at least one deviated image, which forms with the source image a set of monoscopic images. At least one stereoscopic image pair is selected from such a set for use in generating different viewpoints for multiview and stereoscopic purposes, including still and moving images.

A video game character or avatar is generated using images of the player so that the on-screen avatar being controlled by the player appears like the player. Answers to a questionnaire or a psychological profile are provided by the player to determine characteristics that the player views as desirable, which are used to generate a final version of the avatar. Iterations of the avatar appearance are generated from the initial appearance to the final, more desirable appearance. Using the avatar, as play of the game proceeds the player's avatar begins as a character appearing like themselves and gradually becomes a character that is more as they would like to appear. The avatar increases the emotional impact of games by providing strong visual and psychological connections with the player. The avatar may instead begin from an initial character that does not appear similar to the player. The iterations may make the avatar gradually less appealing or with other changes in appearance, in some embodiments.

A near-eye display projects virtual images from an image generator to an eyebox within which the virtual images can be seen by a viewer. A first optical path conveys image-bearing light from the image generator to a selectively reflective powered optic and a second optical path conveys the image-bearing light along a line of sight from the selectively reflective powered optic to the eyebox. First and second selectively reflective surfaces fold the first optical path with respect to the second optical path to locate the image generator out of the line of sight to the eyebox. The image generator is effectively inclined to the line of sight to the eyebox for reducing a thickness of the near-eye display. The selectively reflective powered optic is oriented normal to local overlapping portions of the first and second optical paths at the selectively reflective powered optic.
