Cool-chic
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.
