An Image-like Diffusion Method for Human-Object Interaction Detection

CVPR 2025poster

Human-object interaction (HOI) detection often faces high levels of ambiguity and indeterminacy, as the same interaction can appear vastly different across different human-object pairs. Additionally, the indeterminacy can be further exacerbated by issues such as occlusions and cluttered backgrounds.…

Boundary Probing for Input Privacy Protection When Using LMM Services

ICCV 2025poster

Alongside the rapid development of Large Multimodal Models (LMMs) like GPT-4V, privacy concerns also rise. As LMMs are commonly deployed as cloud services, users are typically required to upload their personal images and videos to the cloud to access these services, raising great concerns about visu…

Class-Agnostic Object Counting with Text-to-Image Diffusion Model

ECCV 2024poster

"Class-agnostic object counting aims to count objects of arbitrary classes with limited information (, a few exemplars or the class names) provided. It requires the model to effectively acquire the characteristics of the target objects and accurately perform counting, which can be challenging. In th…

SemTrack: A Large-scale Dataset for Semantic Tracking in the Wild

ECCV 2024poster

"Knowing merely where the target is located is not sufficient for many real-life scenarios. In contrast, capturing rich details about the tracked target via its semantic trajectory, i.e. who/what this target is interacting with and when, where, and how they are interacting over time, is especially c…

LMC: Large Model Collaboration with Cross-assessment for Training-Free Open-Set Object Recognition

NeurIPS 2023poster

Open-set object recognition aims to identify if an object is from a class that has been encountered during training or not. To perform open-set object recognition accurately, a key challenge is how to reduce the reliance on spurious-discriminative features. In this paper, motivated by that different…
