Improving the Training of Data-Efficient GANs via Quality Aware Dynamic Discriminator Rejection Sampling

CVPR 2025poster

Data-Efficient Generative Adversarial Nets (DE-GANs) have become more and more popular in recent years. Existing methods apply data augmentation, noise injection and pre-trained models to maximumly increase the number of training samples thus improving the training of DE-GANs. However, none of these…

Training Diffusion-based Generative Models with Limited Data

ICML 2025poster

Diffusion-based generative models (diffusion models) often require a large amount of data to train a score-based model that learns the score function of the data distribution through denoising score matching. However, collecting and cleaning such data can be expensive, time-consuming, and even infea…

Neural Sign Actors: A Diffusion Model for 3D Sign Language Production from Text

CVPR 2024poster

Sign Languages (SL) serve as the primary mode of communication for the Deaf and Hard of Hearing communities. Deep learning methods for SL recognition and translation have achieved promising results. However Sign Language Production (SLP) poses a challenge as the generated motions must be realistic a…

Spatio-temporal Prompting Network for Robust Video Feature Extraction

ICCV 2023poster

The frame quality deterioration problem is one of the main challenges in the field of video understanding. To compensate for the information loss caused by deteriorated frames, recent approaches exploit transformer-based integration modules to obtain spatio-temporal information. However, these integ…

Efficient One-Stage Video Object Detection by Exploiting Temporal Consistency

ECCV 2022poster

"Recently, one-stage detectors have achieved competitive accuracy and faster speed compared with traditional two-stage detectors on image data. However, in the field of video object detection (VOD), most existing VOD methods are still based on two-stage detectors. Moreover, directly adapting existin…

TDViT: Temporal Dilated Video Transformer for Dense Video Tasks

ECCV 2022poster

"Deep video models, for example, 3D CNNs or video transformers, have achieved promising performance on sparse video tasks, i.e., predicting one result per video. However, challenges arise when adapting existing deep video models to dense video tasks, i.e., predicting one result per frame. Specifical…

MAMBA: Multi-level Aggregation via Memory Bank for Video Object Detection

AAAI 2021technical

State-of-the-art video object detection methods maintain a memory structure, either a sliding window or a memory queue, to enhance the current frame using attention mechanisms. However, we argue that these memory structures are not efficient or sufficient because of two implied operations: (1) conca…
