Self-Supervised Cross-Level Consistency Learning For Fundus Image Classification

ICASSP 2024accepted

The rapid development of intelligent systems for eye disease diagnosis decreases the risk of people suffering from vision impairment. However, the superior discrimination ability of existing retinal disease diagnosis methods heavily relies on the large-scale high-quality annotations. In this work, w…

AdaptiveMix: Improving GAN Training via Feature Space Shrinkage

CVPR 2023poster

Due to the outstanding capability for data generation, Generative Adversarial Networks (GANs) have attracted considerable attention in unsupervised learning. However, training GANs is difficult, since the training distribution is dynamic for the discriminator, leading to unstable image representatio…

BoxDiff: Text-to-Image Synthesis with Training-Free Box-Constrained Diffusion

ICCV 2023poster

Recent text-to-image diffusion models have demonstrated an astonishing capacity to generate high-quality images. However, researchers mainly studied the way of synthesizing images with only text prompts. While some works have explored using other modalities as conditions, considerable paired data, e…

Dynamically Masked Discriminator for GANs

NeurIPS 2023poster

Training Generative Adversarial Networks (GANs) remains a challenging problem. The discriminator trains the generator by learning the distribution of real/generated data. However, the distribution of generated data changes throughout the training process, which is difficult for the discriminator to…

NewsNet: A Novel Dataset for Hierarchical Temporal Segmentation

CVPR 2023poster

Temporal video segmentation is the get-to-go automatic video analysis, which decomposes a long-form video into smaller components for the following-up understanding tasks. Recent works have studied several levels of granularity to segment a video, such as shot, event, and scene. Those segmentations…

Effective Presentation Attack Detection Driven by Face Related Task

ECCV 2022poster

"The robustness and generalization ability of Presentation Attack Detection (PAD) methods is critical to ensure the security of Face Recognition Systems (FRSs). However, in a real scenario, Presentation Attacks (PAs) are various and it is hard to predict the Presentation Attack Instrument (PAI) spec…
