Edge-adaptive upsampling of depth map videos for enhanced free viewpoint video quality
journal contribution
posted on 2016-10-10, 10:11 authored by Erhan Ekmekcioglu, Marta Mrak, Stewart T. Worrall, Ahmet KondozQuality enhancement of free-viewpoint videos is addressed for 3D
video systems that use the colour texture video plus depth map representation
format. More specifically, a novel and efficient shape adaptive
filter is presented for upsampling depth map videos that are of
lower resolution than their colour texture counterparts. Either measurement
or estimation of depth map videos can take place at lower resolution.
At the same time, depth map reconstruction takes place at low
resolution if reduced resolution compression techniques are utilised.
The proposed design is based on the observation that significant
transitions in depth intensity across depth map frames influence the
overall quality of generated free-viewpoint videos. Hence, sharpness
and accuracy in the free-viewpoint videos rendered using 3D
geometry via depth maps, especially across object borders, are targeted.
Accordingly, significant enhancement of rendered free-viewpoint video
quality is obtained when the proposed method is applied on top of
MPEG spatial scalability filters.
