Video results

Video compression performance are presented on the entire JVET test sequences. PSNR in the YUV420 domain are obtained as follows:

\[\mathrm{PSNR_{YUV420}} = -10 \log_{10} \left(\frac{4\mathrm{MSE}_Y + \mathrm{MSE}_U + \mathrm{MSE}_V}{6}\right).\]

Random-access compression

The following table sums up the compression performance obtained by Cool-chic 4.0 against several conventional codecs in a random access configuration settings. An intra period of 32 frames is used. Results are measure through BD-rates which represents the relative rate required for Cool-chic to obtain the same quality than some other codec.

Sequence	BD-rate of Cool-chic 4.0.0 against [%]			Decoding complexity
	HEVC (HM 16)	HEVC (x265-medium)	AVC (x264-medium)	MAC / pixel	Frame rate [fps]
C-BasketballDrill	+59.6	+15.2	-11.5	946	18.3
C-BQMall	+128.7	+49.3	+20.6	945	16.7
C-PartyScene	+113.0	+37.9	+20.3	946	17.5
C-RaceHorses	+118.7	+41.0	+19.3	950	16.5
Average	+105.0	+35.9	+12.2	947	17.3

Decoding time are obtained on a single CPU core of an Intel Core i9-9940X CPU @ 3.30GHz Processor.
