“…Many follow-up works have been centered around enhancing the autoencoder network [9,8] and/or improving the prior modeling [30,9]. Lately, there have been few attempts at introducing normalizing flow models [28,13] to learned image compression Inspired by the success of learned image compression, research on learned video compression is catching up quickly. However, most end-to-end learned video compression systems [26,27,24,14,32] were developed based primarily on the traditional, hybrid-based coding architecture, replacing key components, such as inter-frame prediction and residual coding, with neural networks.…”
