(b) our proposed architecture with ReLU modifications. Recent works have revealed the great potential in lossy image compression using deep learning. In our model, we empirically set =1.54e3 and Mmax=100 when optimizing for VMAF. Two recent studies adopted structural similarity functions as loss layers of image generation models, obtaining improved results, as validated by conducting a human subjective study (Snell et al., 2017) and by objective evaluation against several other perceptual models (Zhao et al., 2017).
