ObjEmbed: Towards Universal Multimodal Object Embeddings

ICML 2026poster

Aligning objects with corresponding textual descriptions is a fundamental challenge and a realistic requirement in vision-language understanding. While recent multimodal embedding models excel at global image-text alignment, they often struggle with fine-grained alignment between image regions and s…

WeDetect: Fast Open-Vocabulary Object Detection as Retrieval

CVPR 2026

Open-vocabulary object detection aims to detect arbitrary classes via text prompts. Methods without cross-modal fusion layers (non-fusion) offer faster inference by treating recognition as a retrieval problem, i.e., matching regions to text queries in a shared embedding space. In this work, we fully

Spatial-Semantic Collaborative Cropping for User Generated Content

AAAI 2024technical

A large amount of User Generated Content (UGC) is uploaded to the Internet daily and displayed to people world-widely through the client side (mobile and PC). This requires the cropping algorithms to produce the aesthetic thumbnail within a specific aspect ratio on different devices. However, existi…

Self-Supervised Object Localization with Joint Graph Partition

AAAI 2022technical

Object localization aims to generate a tight bounding box for the target object, which is a challenging problem that has been deeply studied in recent years. Since collecting bounding-box labels is time-consuming and laborious, many researchers focus on weakly supervised object localization (WSOL).…

Context Decoupling Augmentation for Weakly Supervised Semantic Segmentation

ICCV 2021poster

Data augmentation is vital for deep learning neural networks. By providing massive training samples, it helps to improve the generalization ability of the model. Weakly supervised semantic segmentation (WSSS) is a challenging problem that has been deeply studied in recent years, conventional data au…

Self-Supervised 3D Skeleton Action Representation Learning With Motion Consistency and Continuity

ICCV 2021poster

Recently, self-supervised learning (SSL) has been proved very effective and it can help boost the performance in learning representations from unlabeled data in the image domain. Yet, very little is explored about its usefulness in 3D skeleton-based action recognition understanding. Directly applyin…

Human Interaction Learning on 3D Skeleton Point Clouds for Video Violence Recognition

ECCV 2020poster

This paper introduces a new method for recognizing violent behavior by learning contextual relationships between related people from human skeleton points. Unlike previous work, we first formulate 3D skeleton point clouds from human skeleton sequences extracted from videos and then perform interacti…
