摘要:
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.

摘要:
Technologies are generally described herein for displaying stereoscopic three-dimensional and multiview stereoscopic three-dimensional visual information on curvilinear display surfaces. The display devices can include a control system configured to execute various methods for obtaining the visual information and displaying the visual information on the curvilinear display surface. If the visual information is intended for display on a first display surface, the control system can modify the visual information for display on the curvilinear display surface. The control system also can modify the visual information based upon relative positions and orientations of a viewer, projector, and/or the display surface, as well as to correct for anticipated environmental or optical interference. The control system outputs the visual information or modified visual information to a display device for display on a curvilinear display surface.

The invention relates to a method and an apparatus for generating a depth map from a digital monoscopic color image. The method includes the following general steps: a) obtaining a first color component of the MCI, said first color component corresponding to partial color information of the MCI; and, b) assigning depth values to pixels of the MCI based on values of the first color component of respective pixels for forming the depth map for the MCI. In one embodiment, the depth values are generated by adjusting and/or scaling of pixel values of the Cr chroma component of the monoscopic source color image in the Y′CbCr color system.

The invention relates to a method and a graphical user interface for modifying a depth map for a digital monoscopic color image. The method includes interactively selecting a region of the depth map based on color of a target region in the color image, and modifying depth values in the thereby selected region of the depth map using a depth modification rule. The color-based pixel selection rules for the depth map and the depth modification rule selected based on one color image from a video sequence may be saved and applied to automatically modify depths maps of other color images from the same sequence.
摘要:
This invention relates to reducing bandwidth requirements for stereoscopic imagery and video signals. The invention comprises a method of producing two streams of images or signals for producing images, separately for the left eye and for the right eye. One image of each stereoscopic pair in the streams is of reduced quality relative to the other. On occurrence of a significant change in image content, or similar occurrence, the image quality of the two streams are switched or transposed, whereby the higher quality image is seen alternately by one eye and then the other. Intervals between switching are indeterminate, and such switching is continued for the duration of the streams of images or video signals.
