In this condition, we have only number 20
and 40 views. Thus when we get away from these
anchor views, PSNR are decreasing. Especially extrapolation
cases (view< 20; 40 > view) are obvious.
Figure 3(b) shows 4 DIBR modes and the local system
as a reference. 2 view cases of the 2V2D and
the 2V1DP keep high quality in range of view 20 to
Table 2: PSNR of various methods at xed view-
point.

40, while in 1 view cases of the left view’s (1V1D:L)
and the right view’s (1V1D:R) 1V1D mode, the image
quality is rapidly decreasing. Comparing to the
2V2D and 2V1DP at the viewpoint 30, the difference
of the image quality is 0.13 dB. PSNR values at some
specified viewpoint are listed in Table 2.
