Abstract
This contribution reports the EE1-2.3 test results, which is a combination of JVET-AB0076 and JVET-JVET-AB0102 test 2.1.1. At each GOP, the encoder can adaptively select a scale factor from ×1.0 and ×2.0 and CNN-based super-resolution is utilized for the latter case. Compared with VTM-11.0-NNVC-3.0, the experimental results show {-4.78%, 2.36%, 4.53%} and {-0.72%, 2.71%, 4.27%} BD-rate changes on average (A1 and A2) for {Y, Cb, Cr} under AI and RA configurations, respectively.
