Learning Dynamic Similarity by Bidirectional Hierarchical Sliding Semantic Probe for Efficient Text Video Retrieval

AAAI 2025technical

Text-video retrieval is a foundation task in multi-modal research which aims to align texts and videos in the embedding space. The key challenge is to learn the similarity between videos and texts. A conventional approach involves directly aligning video-text pairs using cosine similarity. However,…

MUPO-Net: A Multilevel Dual-domain Progressive Enhancement Network with Embedded Attention for CT Metal Artifact Reduction

ICASSP 2025accepted

Metal implants in patients cause severe streaking artifacts in computed tomography (CT) images, significantly compromising image quality. Deep learning methods have been successfully applied to metal artifact reduction (MAR) in CT, but often result in overly smooth images, failing to reconstruct com…

Modality Modulation and Dual Consistency for Multi-Modality Semi-Supervised Medical Image Segmentation

ICASSP 2025accepted

Multi-modality (MM) semi-supervised learning (SSL) based medical image segmentation has recently gained increasing attention due to its ability to utilize MM data and low dependency on labeled images. However, current MM-SSL methods face two major challenges: (1) Complex network designs make it diff…

Multi-view Granular-ball Contrastive Clustering

AAAI 2025technical

Previous multi-view contrastive learning methods typically operate at two scales: instance-level and cluster-level. The former generally constructs positive and negative pairs based on the correspondence between samples and view instances. These methods aim to bring positive pairs closer and push…
