LatentWarp: Consistent Diffusion Latents for Zero-Shot Video-to-Video Translation

no code implementations1 Nov 2023 Yuxiang Bao, Di Qiu, Guoliang Kang, Baochang Zhang, Bo Jin, Kaiye Wang, Pengfei Yan

As a result, the corresponding regions across the adjacent frames can share closely-related query tokens and attention outputs, which can further improve latent-level consistency to enhance visual temporal coherence of generated videos.

Learn to Cluster Faces via Pairwise Classification

no code implementations ICCV 2021 Junfu Liu, Di Qiu, Pengfei Yan, Xiaolin Wei

However, they usually suffer from excessive memory consumption especially on large-scale graphs, and rely on empirical thresholds to determine the connectivities between samples in inference, which restricts their applications in various real-world scenes.

Guided Collaborative Training for Pixel-wise Semi-Supervised Learning

1 code implementation ECCV 2020 Zhanghan Ke, Di Qiu, Kaican Li, Qiong Yan, Rynson W. H. Lau

Although SSL methods have achieved impressive results in image classification, the performances of applying them to pixel-wise tasks are unsatisfactory due to their need for dense outputs.

Towards Geometry Guided Neural Relighting with Flash Photography

no code implementations12 Aug 2020 Di Qiu, Jin Zeng, Zhanghan Ke, Wenxiu Sun, Chengxi Yang

By incorporating the depth map, our approach is able to extrapolate realistic high-frequency effects under novel lighting via geometry guided image decomposition from the flashlight image, and predict the cast shadow map from the shadow-encoding transformed depth map.

Modal Uncertainty Estimation via Discrete Latent Representation

no code implementations25 Jul 2020 Di Qiu, Lok Ming Lui

We motivate our use of discrete latent space through the multi-modal posterior collapse problem in current conditional generative models, then develop the theoretical background, and extensively validate our method on both synthetic and realistic tasks.

Gradient Regularized Contrastive Learning for Continual Domain Adaptation

no code implementations25 Jul 2020 Peng Su, Shixiang Tang, Peng Gao, Di Qiu, Ni Zhao, Xiaogang Wang

At the core of our method, gradient regularization plays two key roles: (1) enforces the gradient of contrastive loss not to increase the supervised training loss on the source domain, which maintains the discriminative power of learned features; (2) regularizes the gradient update on the new domain not to increase the classification loss on the old target domains, which enables the model to adapt to an in-coming target domain while preserving the performance of previously observed domains.

Adapting Object Detectors with Conditional Domain Normalization

no code implementations ECCV 2020 Peng Su, Kun Wang, Xingyu Zeng, Shixiang Tang, Dapeng Chen, Di Qiu, Xiaogang Wang

Then this domain-vector is used to encode the features from another domain through a conditional normalization, resulting in different domains' features carrying the same domain attribute.
