Comprehensive Comparisons of Uniform Quantization in Deep Image Compression

1 code implementation1 Mar 2023 Koki Tsubota, Kiyoharu Aizawa

The experimental results reveal that the best approximated quantization differs by the network architectures, and the best approximations of the three are different from the original ones used for the architectures.
