GRACE: Loss-Resilient Real-Time Video through Neural Codecs.
In
NSDI, 2024.
We present a loss-resilient real-time video system called GRACE, which preserves the user's quality of experience (QoE) across a wide range of packet losses through an autoencoder-based neural video codec.
Online Overexposed Pixels Hallucination in Videos with Adaptive Reference Frame Selection.
In
arXiV, 2023.
We present a learning-based system to hallucinate HDR content in overexposed video sequences, without resorting to complex acquisition mechanisms like alternating exposures or costly processing typical of HDR imaging.
AI-Mediated 3D Video Conferencing.
