Depth-Image-Based Rendering (DIBR)

DIBR is a technique to synthesize a non-captured view (virtual) using some of the captured (reference) views of the 3D world.

Free Viewpoint Streaming

A DASH-based Free Viewpoint Video Streaming System [1]
  • They have proposed a framework for adaptive free-viewpoint video streaming.
  • They have developed an empirical rate-distortion model for MVD (multi-view-plus-depth) videos.
  • They have developed two DIBR implementations which exploit graphics processing units (GPUs) to speed up the view synthesis process. The first implementation performs double warping view synthesis for an arbitrary camera arrangement. The second implementation performs horizontal pixel shifting for 1D parallel camera arrangements or rectified camera views. Both implementations use the OpenGL graphics API to perform the different stages of the view synthesis process.

Adaptive Streaming of Interactive Free Viewpoint Videos to Heterogeneous Clients [2]

  • This is extended version of [1].
  • They have predicted user's view request using a simple location estimation technique known as dead reckoning.
  • They have developed a virtual view distortion model which is based on mathematical analysis. It stills needs some pre-measured rate-distortion points to find the model's parameters.

DIBR for FVV

In [1], they have used Depth-Image-Based Rendering (DIBR) to synthesize a non-reference video from reference views (free-viewpoint application).
