EKMEKCIOGLU, E., WORRALL, S. and KONDOZ, A., 2008. Utilisation of downsampling for arbitrary views in multi-view video coding. Electronics Letters, 44 (5), pp.339-340.
The effect of using downsampling for arbitrary views inside a multiview
sequence on the multi-view coding (MVC) efficiency is explored.
A bit rate adaptive approach is proposed to consider downsampling
certain views prior to encoding with relevant downscaling ratios. The
inter-view references, if any, are downsampled to the same resolution
and the decoded view is upsampled back to the original resolution.
The results over several multi-view test sequences imply that up to
0.9 dB gain or 20% reduction in bit rate can be achieved, reducing
the computational complexity in the encoder significantly at the
