The results for 4K test sequences in Table
9.2
are summarized in Table
9.9
(Random Access Main only). We observe a coding efficiency improvement of up
to 76 % for HEVC.
In addition, still picture coding performance of HEVC based intra coding,
relative to JPEG and AVC intra coding is reported in [
18
]. The results show
that bit rate reductions due to HEVC intra coding are about 44 and 32 %,
respectively. Comparisons of HEVC intra coding to JPEG and JPEG2000 by means
of objective and subjective evaluations are also reported in [
9
]. The evaluation
