Low-latency Space-time Supersampling for Real-time Rendering

1 code implementation18 Dec 2023 Ruian He, Shili Zhou, Yuqi Sun, Ri Cheng, Weimin Tan, Bo Yan

With the rise of real-time rendering and the evolution of display devices, there is a growing demand for post-processing methods that offer high-resolution content in a high frame rate.

Context-Aware Iteration Policy Network for Efficient Optical Flow Estimation

no code implementations12 Dec 2023 Ri Cheng, Ruian He, Xuhao Jiang, Shili Zhou, Weimin Tan, Bo Yan

In this paper, we develop a Context-Aware Iteration Policy Network for efficient optical flow estimation, which determines the optimal number of iterations per sample.

Unsupervised Disentangling of Facial Representations with 3D-aware Latent Diffusion Models

1 code implementation15 Sep 2023 Ruian He, Zhen Xing, Weimin Tan, Bo Yan

Second, we propose a novel representation diffusion model (RDM) to disentangle 3D latent into facial identity and expression.

Uncertainty-Guided Spatial Pruning Architecture for Efficient Frame Interpolation

no code implementations31 Jul 2023 Ri Cheng, Xuhao Jiang, Ruian He, Shili Zhou, Weimin Tan, Bo Yan

We can use dynamic spatial pruning method to skip redundant computation, but this method cannot properly identify easy regions in VFI tasks without supervision.

Instruct-NeuralTalker: Editing Audio-Driven Talking Radiance Fields with Instructions

no code implementations19 Jun 2023 Yuqi Sun, Ruian He, Weimin Tan, Bo Yan

Given a short speech video, we first build an efficient talking radiance field, and then apply the latest conditional diffusion model for image editing based on the given instructions and guiding implicit representation optimization towards the editing target.

Feature Pyramid Network for Multi-task Affective Analysis

1 code implementation8 Jul 2021 Ruian He, Zhen Xing, Weimin Tan, Bo Yan

Affective Analysis is not a single task, and the valence-arousal value, expression class, and action unit can be predicted at the same time.
