Another representative 3D content format is DIBR
. This format stores the center image and the gray-level depth map for the same scene.

Depth video is the auxiliary information in DIBR
, and the characteristics of depth maps are different from those of the corresponding color video.
Instead of using raw data of multiviewed images, the DIBR
technique makes use of two types of images: 2D texture images and synchronized depth maps.
Compared to DIBR
and IDW, this new warping method didn't rely on depth estimation or sparse linear equations calculation, but applied the robust SIFT features, which can work out an expected homography rapidly.
Under the programme, pilot measures are being introduced in the Dibr
and Fier regions, and recommendations drawn up for the reform of the health system.
Normally, the 2D-to-3D conversion process is distributed into two basic steps: depth estimation for a given 2D image and subsequent Depth Image Based Rendering (DIBR
) of a query image to form a stereopair.
Depth-Image-Based Rendering (DIBR
) is widely used for view synthesis in 3D video coding.
In 2D-to-3D video conversion process, the virtual left and right view can be generated from 2D video and its corresponding depth map by depth image based rendering (DIBR
In 3D video coding system, depth maps are not directly provided to viewers but are used to synthesize the virtual views by DIBR
(Depth Image Based Rendering) algorithm .
With a few pairs of depth and color images from neighboring views in MVD, arbitrary intermediate views can be synthesized via the depth-image-based rendering (DIBR
) technique .
