Web25 de jun. de 2024 · We further reuse the VQ-VAE to calculate two feature losses, which help improve structure coherence and texture realism, respectively. Experimental results on CelebA-HQ, Places2, and ImageNet datasets show that our method not only enhances the diversity of the inpainting solutions but also improves the visual quality of the generated … Webexperiments). We use the released VQ-VAE implementation in the Sonnet library 2 3. 3 Method The proposed method follows a two-stage approach: first, we train a hierarchical VQ-VAE (see Fig. 2a) to encode images onto a discrete latent space, and then we fit a powerful PixelCNN prior over the discrete latent space induced by all the data.
