AnaMoDiff: 2D Analogical Motion Diffusion via Disentangled Denoising

no code implementations5 Feb 2024 Maham Tanveer, Yizhi Wang, Ruiqi Wang, Nanxuan Zhao, Ali Mahdavi-Amiri, Hao Zhang

We present AnaMoDiff, a novel diffusion-based method for 2D motion analogies that is applied to raw, unannotated videos of articulated characters.

Slice3D: Multi-Slice, Occlusion-Revealing, Single View 3D Reconstruction

no code implementations3 Dec 2023 Yizhi Wang, Wallace Lira, Wenqi Wang, Ali Mahdavi-Amiri, Hao Zhang

Our key observation is that object slicing is more advantageous than altering views to reveal occluded structures.

Quantum generative adversarial learning in photonics

no code implementations1 Oct 2023 Yizhi Wang, Shichuan Xue, Yaxuan Wang, Yong liu, Jiangfang Ding, Weixu Shi, Dongyang Wang, Yingwen Liu, Xiang Fu, Guangyao Huang, Anqi Huang, Mingtang Deng, Junjie Wu

Quantum Generative Adversarial Networks (QGANs), an intersection of quantum computing and machine learning, have attracted widespread attention due to their potential advantages over classical analogs.

BRICS: Bi-level feature Representation of Image CollectionS

no code implementations29 May 2023 Dingdong Yang, Yizhi Wang, Ali Mahdavi-Amiri, Hao Zhang

Our key codes and feature grids are jointly trained continuously with well-defined gradient flows, leading to high usage rates of the feature grids and improved generative modeling compared to discrete Vector Quantization (VQ).

DeepVecFont-v2: Exploiting Transformers to Synthesize Vector Fonts with Higher Quality

1 code implementation CVPR 2023 Yuqing Wang, Yizhi Wang, Longhui Yu, Yuesheng Zhu, Zhouhui Lian

First, we adopt Transformers instead of RNNs to process sequential data and design a relaxation representation for vector outlines, markedly improving the model's capability and stability of synthesizing long and complex outlines.

DS-Fusion: Artistic Typography via Discriminated and Stylized Diffusion

1 code implementation ICCV 2023 Maham Tanveer, Yizhi Wang, Ali Mahdavi-Amiri, Hao Zhang

We introduce a novel method to automatically generate an artistic typography by stylizing one or more letter fonts to visually convey the semantics of an input word, while ensuring that the output remains readable.

ARO-Net: Learning Implicit Fields from Anchored Radial Observations

1 code implementation CVPR 2023 Yizhi Wang, Zeyu Huang, Ariel Shamir, Hui Huang, Hao Zhang, Ruizhen Hu

We introduce anchored radial observations (ARO), a novel shape encoding for learning implicit field representation of 3D shapes that is category-agnostic and generalizable amid significant shape variations.

Aesthetic Text Logo Synthesis via Content-aware Layout Inferring

1 code implementation CVPR 2022 Yizhi Wang, Guo Pu, Wenhan Luo, Yexin Wang, Pengfei Xiong, Hongwen Kang, Zhouhui Lian

To train and evaluate our approach, we construct a dataset named as TextLogo3K, consisting of about 3, 500 text logo images and their pixel-level annotations.

Attribute2Font: Creating Fonts You Want From Attributes

2 code implementations16 May 2020 Yizhi Wang, Yue Gao, Zhouhui Lian

To the best of our knowledge, our model is the first one in the literature which is capable of generating glyph images in new font styles, instead of retrieving existing fonts, according to given values of specified font attributes.

Boosting Scene Character Recognition by Learning Canonical Forms of Glyphs

1 code implementation12 Jul 2019 Yizhi Wang, Zhouhui Lian, Yingmin Tang, Jianguo Xiao

In this paper, we propose a novel methodology for boosting scene character recognition by learning canonical forms of glyphs, based on the fact that characters appearing in scene images are all derived from their corresponding canonical forms.

Graphical Time Warping for Joint Alignment of Multiple Curves

no code implementations NeurIPS 2016 Yizhi Wang, David J. Miller, Kira Poskanzer, Yue Wang, Lin Tian, Guoqiang Yu

We name the proposed approach graphical time warping (GTW), emphasizing the graphical nature of the solution and that the dependency structure of the warping functions can be represented by a graph.
