Leveraging Anatomical Consistency for Multi-Object Detection in Ultrasound Images via Source-free Unsupervised Domain Adaptation

AAAI 2025technical

Source-free unsupervised domain adaptation aims to eliminate domain shifts when data from the source domain and annotation from the target domain are not available. The multi-object detection tasks in medical image analysis are constrained by patient privacy and extremely huge annotation consumption…

Bidirectional Recurrence for Cardiac Motion Tracking with Gaussian Process Latent Coding

NeurIPS 2024poster

Quantitative analysis of cardiac motion is crucial for assessing cardiac function. This analysis typically uses imaging modalities such as MRI and Echocardiograms that capture detailed image sequences throughout the heartbeat cycle. Previous methods predominantly focused on the analysis of image pai…

C^2RV: Cross-Regional and Cross-View Learning for Sparse-View CBCT Reconstruction

CVPR 2024poster

Cone beam computed tomography (CBCT) is an important imaging technology widely used in medical scenarios such as diagnosis and preoperative planning. Using fewer projection views to reconstruct CT also known as sparse-view reconstruction can reduce ionizing radiation and further benefit intervention…

CardiacNet: Learning to Reconstruct Abnormalities for Cardiac Disease Assessment from Echocardiogram Videos

ECCV 2024oral

"Echocardiogram video plays a crucial role in analysing cardiac function and diagnosing cardiac diseases. Current deep neural network methods primarily aim to enhance diagnosis accuracy by incorporating prior knowledge, such as segmenting cardiac structures or lesions annotated by human experts. How…

Unsupervised Domain Adaptation for Anatomical Structure Detection in Ultrasound Images

ICML 2024poster

Models trained on ultrasound images from one institution typically experience a decline in effectiveness when transferred directly to other institutions. Moreover, unlike natural images, dense and overlapped structures exist in fetus ultrasound images, making the detection of structures more challen…

RSCFed: Random Sampling Consensus Federated Semi-Supervised Learning

CVPR 2022poster

Federated semi-supervised learning (FSSL) aims to derive a global model by jointly training fully-labeled and fully-unlabeled clients. The existing approaches work well when local clients have independent and identically distributed (IID) data but fail to generalize to a more practical FSSL setting,…

ME-PCN: Point Completion Conditioned on Mask Emptiness

ICCV 2021poster

Point completion refers to completing the missing geometries of an object from incomplete observations. Main-stream methods predict the missing shapes by decoding a global feature learned from the input point cloud, which often leads to deficient results in preserving topology consistency and surfac…

FPConv: Learning Local Flattening for Point Convolution

CVPR 2020poster

We introduce FPConv, a novel surface-style convolution operator designed for 3D point cloud analysis. Unlike previous methods, FPConv doesn't require transforming to intermediate representation like 3D grid or graph and directly works on surface geometry of point cloud. To be more specific, for each…

Skeleton-bridged Point Completion: From Global Inference to Local Adjustment

NeurIPS 2020poster

Point completion refers to complete the missing geometries of objects from partial point clouds. Existing works usually estimate the missing shape by decoding a latent feature encoded from the input points. However, real-world objects are usually with diverse topologies and surface details, which a…
