An example of depth map Generating and reconstructing 3D shapes from single or multi-view depth maps or silhouettes [10] The major steps of depth-based conversion methods are: Depth budget allocation – how much total depth in the scene and where the screen plane will be. Image segmentation, creation of mattes or masks, usually by rotoscoping ...
The 2D-plus-Depth format is described in a Philips' white paper [3] and articles. [4]Each 2D image frame is supplemented with a greyscale depth map which indicates if a specific pixel in the 2D image needs to be shown in front of the display (white) or behind the screen plane (black).
Stereoscopic depth rendition specifies how the depth of a three-dimensional object is encoded in a stereoscopic reconstruction. It needs attention to ensure a realistic depiction of the three-dimensionality of viewed scenes and is a specific instance of the more general task of 3D rendering of objects in two-dimensional displays.
Using just one (optional) lens, this camera can take 2D photos, 3D photos, or Full HD movies, simply by changing the mode. The optional lens is a proprietary, 45mm f/1.8 prime lens . The NX300 has two LCD screens in the optical path which are used to "black out" their respective half of the lens, sending a slightly different image to the sensor.
Computer stereo vision is the extraction of 3D information from digital images, such as those obtained by a CCD camera. By comparing information about a scene from two vantage points, 3D information can be extracted by examining the relative positions of objects in the two panels. This is similar to the biological process of stereopsis.
A bitmap image holding depth values (either a Z buffer or a W buffer), used for visible surface determination, during rasterization of 3D scenes Depth map A bitmap image or texture map holding depth values. Similar to a height map or displacement map, but usually associated with a projection. Depth value
A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.
These data can be used to aid inter-view image compression or to generate stereoscopic pairs for multiple different view angles and screen sizes. 2D plus depth processing can be used to recreate 3D scenes even from a single view and convert legacy film and video material to a 3D look, though a convincing effect is harder to achieve and the ...
