Cross-modal Collaborative Representation Learning for Text-to-Image Person Retrieval

IJCAI 2025

Text-to-image person retrieval (TIPR) aims to find images of the same identity that match a given text description. Current TIPR methods mainly focus on mining the association between images and texts, ignoring their potential complementarity. Besides, existing matching losses treat all positive pai

Richer Semantics, Better Alignment: Aligning Visual Features with Explicit and Enriched Semantics for Visible-Infrared Person Re-Identification

IJCAI 2025

Visible-infrared person re-identification (VIReID) retrieves pedestrian images with the same identity across different modalities. Existing methods learn visual features solely from images, failing to align them into the modality-invariant semantic space. In this paper, we propose a novel framework,

Enhancing Cross-modal Completion and Alignment for Unsupervised Incomplete Text-to-Image Person Retrieval

IJCAI 2024poster

Traditional text-image person retrieval methods heavily rely on fully matched and identity-annotated multimodal data, representing an ideal yet limited scenario. The issues of handling incomplete multimodal data and the complexities of labeling multimodal data are common challenges encountered in re…

Rethink Pair-Wise Self-Supervised Cross-Modal Retrieval From A Contrastive Learning Perspective

ICASSP 2023accepted

Cross-modal retrieval often faces the challenges of eliminating modality gap, learning robust modality invariance and semantic discrimination. Existing self-supervised crossmodal approaches still suffer from the faulty negative sample selection strategy and the lack of reliable high-level semantic d…

Semantically Contrastive Learning for Low-Light Image Enhancement

AAAI 2022technical

Low-light image enhancement (LLE) remains challenging due to the unfavorable prevailing low-contrast and weak-visibility problems of single RGB images. In this paper, we respond to the intriguing learning-related question -- if leveraging both accessible unpaired over/underexposed images and high-le…

Cross Scene Video Foreground Segmentation Via Co-Occurrence Probability Oriented Supervised and Unsupervised Model Interaction

ICASSP 2021accepted

Using only one deep model for cross scene video foreground segmentation is still very challenging because existing methods are scene-dependent, which restricts the consistent segmentation. In this paper, we propose a cross scene video foreground segmentation framework to extend the generalization ca…

Nlkd: Using Coarse Annotations For Semantic Segmentation Based on Knowledge Distillation

ICASSP 2021accepted

Modern supervised learning relies on a large amount of training data, yet there are many noisy annotations in real datasets. For semantic segmentation tasks, pixel-level annotation noise is typically located at the edge of an object, while pixels within objects are fine-annotated. We argue the coars…
