Can Large Vision-Language Models Detect Images Copyright Infringement from GenAI?

no code implementations23 Feb 2025 Qipan Xu, Zhenting Wang, Xiaoxiao He, Ligong Han, Ruixiang Tang

Our experimental results reveal that LVLMs are prone to overfitting, leading to the misclassification of some negative samples as IP-infringement cases.

New Capability to Look Up an ASL Sign from a Video Example

no code implementations18 Jul 2024 Carol Neidle, Augustine Opoku, Carey Ballard, Yang Zhou, Xiaoxiao He, Gregory Dimitriadis, Dimitris Metaxas

The user submits a video for analysis and is presented with the five most likely sign matches, in decreasing order of likelihood, so that the user can confirm the selection and then be taken to our ASLLRP Sign Bank entry for that sign.

DMCVR: Morphology-Guided Diffusion Model for 3D Cardiac Volume Reconstruction

1 code implementation18 Aug 2023 Xiaoxiao He, Chaowei Tan, Ligong Han, Bo Liu, Leon Axel, Kang Li, Dimitris N. Metaxas

However, current cardiac MRI-based reconstruction technology used in clinical settings is 2D with limited through-plane resolution, resulting in low-quality reconstructed cardiac volumes.

Improving Tuning-Free Real Image Editing with Proximal Guidance

1 code implementation8 Jun 2023 Ligong Han, Song Wen, Qi Chen, Zhixing Zhang, Kunpeng Song, Mengwei Ren, Ruijiang Gao, Anastasis Stathopoulos, Xiaoxiao He, Yuxiao Chen, Di Liu, Qilong Zhangli, Jindong Jiang, Zhaoyang Xia, Akash Srivastava, Dimitris Metaxas

Null-text inversion (NTI) optimizes null embeddings to align the reconstruction and inversion trajectories with larger CFG scales, enabling real image editing with cross-attention control.

Dealing With Heterogeneous 3D MR Knee Images: A Federated Few-Shot Learning Method With Dual Knowledge Distillation

1 code implementation25 Mar 2023 Xiaoxiao He, Chaowei Tan, Bo Liu, Liping Si, Weiwu Yao, Liang Zhao, Di Liu, Qilong Zhangli, Qi Chang, Kang Li, Dimitris N. Metaxas

The supervised learning of the proposed method extracts features from limited labeled data in each client, while the unsupervised data is used to distill both feature and response-based knowledge from a national data repository to further improve the accuracy of the collaborative model and reduce the communication cost.

Recursive 3D Segmentation of Shoulder Joint with Coarse-scanned MR Image

1 code implementation13 Mar 2022 Xiaoxiao He, Chaowei Tan, Virak Tan, Kang Li

For diagnosis of shoulder illness, it is essential to look at the morphology deviation of scapula and humerus from the medical images that are acquired from Magnetic Resonance (MR) imaging.

Effective 3D Humerus and Scapula Extraction using Low-contrast and High-shape-variability MR Data

no code implementations22 Feb 2019 Xiaoxiao He, Chaowei Tan, Yuting Qiao, Virak Tan, Dimitris Metaxas, Kang Li

For the initial shoulder preoperative diagnosis, it is essential to obtain a three-dimensional (3D) bone mask from medical images, e. g., magnetic resonance (MR).
