1. Video coding standards only define the decoding procedure and the corresponding bit stream but do not specify the encoding algorithms.

2. The resolution and frame rate of the “Breakdancers” sequence is $$1024 \times 768$$ pixels and $$15$$ frames per second, respectively.

3. For clarity, the image coordinate axes are labeled in lower case and the world coordinate axes are labeled in upper case.

4. For simplicity, we denote $$(\boldsymbol{h}^m)^T=\boldsymbol{h}^{mT}$$, according to the notation used in [35].

5. Note that the first multiplication represents an inner product and the second equation leads to a scalar.

6. assuming a translational motion

7. Sharing the result of the cost function can be done to enforce spatially consistent disparity values

8. In this case, the symbol $$\phi$$ does not represent an empty set but an undefined element.

9. This selected reference view is left out from the data set for rendering.

10. The discussed alternative method [51] presents the depth image of a different viewpoint and time. However, the properties of the sequence do not vary over time and across the views, so that a subjective comparison is still possible.

11. This remark is similar to a statement of Jean le Rond d’Alembert, a French mathematician, who stated that “Algebra is generous; she often gives more than is asked of her”

12. The resolution of the “Breakdancers” sequence is $$1024 \times 768$$ pixels and the frame rate is 15 frames per second. The compression is performed using an H.264/MPEG-4 AVC encoder with main profile.

13. In [89], the original MPEG sequences were down-sampled such that a comparison with the results presented within MVC is not directly possible.

14. The period of inserted intra-coded frames corresponds to the Group Of Pictures (GOP) size.

15. At the time the presented experiments were performed and published [21]–[23], a simulcast compression constituted the anchor for the coding performance comparisons [32]. In 2007, the reference software JMVM became the anchor for comparisons [85], [90].

16. To derive this equation, the following properties of series are needed: $$\sum_{i=1}^n i = \frac{n(n+1)}{2}$$ and $$\sum_{i=1}^n i^2 = \frac{n(n+1)(2n+1)}{6}$$, where $$i$$ takes the parameter $$x$$ or $$y$$.

17. “Breakdancers” and “Ballet” depth image number 0 of camera 0. Note that the complexity of depth images is not significantly varying over time and across the views, so that including more depth images would not change the results.
