Human-Centric Video Generation via Collaborative Multi-Modal Conditioning

AAAI 2026technical

Human-Centric Video Generation (HCVG) methods seek to synthesize human videos from multimodal inputs, including text, images, and audio. Existing methods struggle to effectively coordinate these heterogeneous modalities due to two challenges: the scarcity of modality-complete data and the difficulty

Phantom-Data: Towards a General Subject-Consistent Video Generation Dataset

ICLR 2026poster

Subject-to-video generation has witnessed substantial progress in recent years. However, existing models still face significant challenges in faithfully following textual instructions. This limitation, commonly known as the copy-paste problem, arises from the widely used in-pair training paradigm. T…

Phantom: Subject-Consistent Video Generation via Cross-Modal Alignment

ICCV 2025poster

The continuous development of foundational models for video generation is evolving into various applications, with subject-consistent video generation still in the exploratory stage. We refer to this as Subject-to-Video, which extracts subject elements from reference images and generates subject-con…

Reinforced Axial Refinement Network for Monocular 3D Object Detection

ECCV 2020poster

Monocular 3D object detection aims to extract the 3D position and properties of objects from a 2D input image. This is an ill-posed problem with a major difficulty lying in the information loss by depth-agnostic cameras. Conventional approaches sample 3D bounding boxes from the space and infer the r…

Deep Fitting Degree Scoring Network for Monocular 3D Object Detection

CVPR 2019poster

In this paper, we propose to learn a deep fitting degree scoring network for monocular 3D object detection, which aims to score fitting degree between proposals and object conclusively. Different from most existing monocular frameworks which use tight constraint to get 3D location, our approach achi…
