SEMC: Structure-Enhanced Mixture-of-Experts Contrastive Learning for Ultrasound Standard Plane Recognition

AAAI 2026technical

Ultrasound standard plane recognition is essential for clinical tasks such as disease screening, organ evaluation, and biometric measurement. However, existing methods fail to effectively exploit shallow structural information and struggle to capture fine-grained semantic differences through contras

BSAFusion: A Bidirectional Stepwise Feature Alignment Network for Unaligned Medical Image Fusion

AAAI 2025technical

If unaligned multimodal medical images can be simultaneously aligned and fused using a single-stage approach within a unified processing framework, it will not only achieve mutual promotion of dual tasks but also help reduce the complexity of the model. However, the design of this model faces the ch…

C2PD: Continuity-Constrained Pixelwise Deformation for Guided Depth Super-Resolution

AAAI 2025technical

Guided depth super-resolution (GDSR) has demonstrated impressive performance across a wide range of domains, with numerous methods being proposed. However, existing methods often treat depth maps as images, where shading values are computed discretely, making them struggle to effectively restore the…

MESC-3D:Mining Effective Semantic Cues for 3D Reconstruction from a Single Image

CVPR 2025poster

Reconstructing 3D shapes from a single image plays an important role in computer vision. Many methods have been proposed and achieve impressive performance. However, existing methods mainly focus on extracting semantic information from images and then simply concatenating it with 3D point clouds wit…

Multi-Agent Motion Forecasting via Mixed Supervision

RA-L 2025

Accurate motion forecasting is critical for safe decision-making in autonomous driving. Existing methods lack explicit supervision during the generation of multimodal candidate trajectories, which leads to inconsistent candidate quality and difficulty balancing trajectory diversity with scene adapta

SGTC: Semantic-Guided Triplet Co-training for Sparsely Annotated Semi-Supervised Medical Image Segmentation

AAAI 2025technical

Although semi-supervised learning has made significant advances in the field of medical image segmentation, fully annotating a volumetric sample slice by slice remains a costly and time-consuming task. Even worse, most of the existing approaches pay much attention to image-level information and igno…

Exploring Cross-Domain Few-Shot Classification via Frequency-Aware Prompting

IJCAI 2024poster

Cross-Domain Few-Shot Learning has witnessed great stride with the development of meta-learning. However, most existing methods pay more attention to learning domain-adaptive inductive bias (meta-knowledge) through feature-wise manipulation or task diversity improvement while neglecting the phenomen…

Spherical Pseudo-Cylindrical Representation for Omnidirectional Image Super-resolution

AAAI 2024technical

Omnidirectional images have attracted significant attention in recent years due to the rapid development of virtual reality technologies. Equirectangular projection (ERP), a naive form to store and transfer omnidirectional images, however, is challenging for existing two-dimensional (2D) image super…
