Dynamic Content Prediction with Motion-aware Priors for Blind Face Video Restoration

CVPR 2025poster

Blind Face Video Restoration (BFVR) focuses on reconstructing high-quality facial image sequences from degraded video inputs. The main challenge is address unknown degradations, while maintaining temporal consistency across frames. Current blind face restoration methods are primarily designed for im…

Learning Degradation-unaware Representation with Prior-based Latent Transformations for Blind Face Restoration

CVPR 2024poster

Blind face restoration focuses on restoring high-fidelity details from images subjected to complex and unknown degradations while preserving identity information. In this paper we present a Prior-based Latent Transformation approach (PLTrans) which is specifically designed to learn a degradation-una…

SCTrans: Multi-scale scRNA-seq Sub-vector Completion Transformer for Gene-selective Cell Type Annotation

IJCAI 2024poster

Cell type annotation is pivotal to single-cell RNA sequencing data (scRNA-seq)-based biological and medical analysis, e.g., identifying biomarkers, exploring cellular heterogeneity, and understanding disease mechanisms. The previous annotation methods typically learn a nonlinear mapping to infer cel…

Text-conditional Attribute Alignment across Latent Spaces for 3D Controllable Face Image Synthesis

CVPR 2024poster

With the advent of generative models and vision language pretraining significant improvement has been made in text-driven face manipulation. The text embedding can be used as target supervision for expression control.However it is non-trivial to associate with its 3D attributesi.e. pose and illumina…

VRetouchEr: Learning Cross-frame Feature Interdependence with Imperfection Flow for Face Retouching in Videos

CVPR 2024poster

Face Video Retouching is a complex task that often requires labor-intensive manual editing. Conventional image retouching methods perform less satisfactorily in terms of generalization performance and stability when applied to videos without exploiting the correlation among frames. To address this i…

Blemish-Aware and Progressive Face Retouching With Limited Paired Data

CVPR 2023poster

Face retouching aims to remove facial blemishes, while at the same time maintaining the textual details of a given input image. The main challenge lies in distinguishing blemishes from the facial characteristics, such as moles. Training an image-to-image translation network with pixel-wise supervisi…

Exploring Intra-Class Variation Factors With Learnable Cluster Prompts for Semi-Supervised Image Synthesis

CVPR 2023poster

Semi-supervised class-conditional image synthesis is typically performed by inferring and injecting class labels into a conditional Generative Adversarial Network (GAN). The supervision in the form of class identity may be inadequate to model classes with diverse visual appearances. In this paper, w…

Text-Guided Unsupervised Latent Transformation for Multi-Attribute Image Manipulation

CVPR 2023poster

Great progress has been made in StyleGAN-based image editing. To associate with preset attributes, most existing approaches focus on supervised learning for semantically meaningful latent space traversal directions, and each manipulation step is typically determined for an individual attribute. To a…

SphericGAN: Semi-Supervised Hyper-Spherical Generative Adversarial Networks for Fine-Grained Image Synthesis

CVPR 2022poster

Generative Adversarial Network (GAN)-based models have greatly facilitated image synthesis. However, the model performance may be degraded when applied to fine-grained data, due to limited training samples and subtle distinction among categories. Different from generic GANs, we address the issue fro…

Semi-Supervised Single-Stage Controllable GANs for Conditional Fine-Grained Image Generation

ICCV 2021poster

Previous state-of-the-art deep generative models improve fine-grained image generation quality by designing hierarchical model structures and synthesizing images across multiple stages. The learning process is typically performed without any supervision in object categories. To address this issue, w…
