Mingzhen Sun, Weining Wang, Xinxin Zhu, Jing Liu

Abstract: Highlights•Propose to reparameterize image features to fully exploit VQ-VAE codebook capacity.•Propose a dynamic method to quantize reparameterized image features.•Propose a novel regularization loss to enhance reconstruction of image details.
