Hierarchical VQ-VAE for Low-Resolution Video Compression

This paper addresses the growing need for efficient video compression, particularly for edge devices and content delivery networks. It proposes a novel Multi-Scale Vector Quantized Variational Autoencoder (MS-VQ-VAE) that generates compact, high-fidelity latent representations of low-resolution video. The use of a hierarchical latent structure and perceptual loss is key to achieving good compression while maintaining perceptual quality. The lightweight nature of the model makes it suitable for resource-constrained environments.
