AsyncDSB: Schedule-Asynchronous Diffusion Schrödinger Bridge for Image Inpainting

no code implementations11 Dec 2024 Zihao Han, Baoquan Zhang, Lisai Zhang, Shanshan Feng, Kenghong Lin, Guotao Liang, Yunming Ye, Xiaochen Qi, Guangming Ye

Although these methods have shown superior performance, in this paper, we find that 1) existing methods suffer from a schedule-restoration mismatching issue, i. e., the theoretical schedule and practical restoration processes usually exist a large discrepancy, which theoretically results in the schedule not fully leveraged for restoring images; and 2) the key reason causing such issue is that the restoration process of all pixels are actually asynchronous but existing methods set a synchronous noise schedule to them, i. e., all pixels shares the same noise schedule.

FashionSAP: Symbols and Attributes Prompt for Fine-grained Fashion Vision-Language Pre-training

1 code implementation CVPR 2023 Yunpeng Han, Lisai Zhang, Qingcai Chen, Zhijian Chen, Zhonghua Li, Jianxin Yang, Zhao Cao

We propose a method for fine-grained fashion vision-language pre-training based on fashion Symbols and Attributes Prompt (FashionSAP) to model fine-grained multi-modalities fashion attributes and characteristics.

Multi-hop Graph Convolutional Network with High-order Chebyshev Approximation for Text Reasoning

1 code implementation ACL 2021 Shuoran Jiang, Qingcai Chen, Xin Liu, Baotian Hu, Lisai Zhang

In this study, we define the spectral graph convolutional network with the high-order dynamic Chebyshev approximation (HDGCN), which augments the multi-hop graph reasoning by fusing messages aggregated from direct and long-term dependencies into one convolutional layer.

Prototype Completion with Primitive Knowledge for Few-Shot Learning

1 code implementation CVPR 2021 Baoquan Zhang, Xutao Li, Yunming Ye, Zhichao Huang, Lisai Zhang

To avoid the prototype completion error caused by primitive knowledge noises or class differences, we further develop a Gaussian based prototype fusion strategy that combines the mean-based and completed prototypes by exploiting the unlabeled samples.

Text-Guided Neural Image Inpainting

1 code implementation7 Apr 2020 Lisai Zhang, Qingcai Chen, Baotian Hu, Shuoran Jiang

To fulfill such a task, we propose a novel inpainting model named Text-Guided Dual Attention Inpainting Network (TDANet).
