Beyond Facial Consistency: Personalized Person Image Generation with Holistic Identity Preservation
Yuxuan Xiao, Shanshan Zhang, Jian Yang +1
Personalized person image generation requires preserving subject identity across both local facial details and broader appearance cues. Existing methods typically emphasize only on…
IREU: Identity-Related Encoder-Only Unlearning for Customized Portrait Generation
Chaoyi Shi, Shanshan Zhang, Jian Yang
Customized Portrait Generation (CPG) technologies have been widely used to generate high-fidelity person images given an input image indicating the identity and a text prompt indic…
One-Shot Novel View and Pose Human Image Synthesis via 3D Prior Guided Diffusion Model
Shenjian Gong, Kangkan Wang, Shanshan Zhang +1
This paper addresses the challenge of one-shot novel view and pose human image synthesis. The existing methods transfer the reference human image to a target pose using a set of 2D…
Shape-Prior-Based Point Cloud Completion for Single-Stage Fully Sparse 3D Object Detection
Kaizheng Wang, Mingqian Ji, Jian Yang +1
Single-stage fully sparse 3D object detectors rely on point clouds data to detect objects in autonomous driving scenarios. However, the sparsity and incompleteness of point clouds…
Revisiting Token Compression for Accelerating ViT-based Sparse Multi-View 3D Object Detectors
Mingqian Ji, Shanshan Zhang, Jian Yang
Vision Transformer (ViT)-based sparse multi-view 3D object detectors have achieved remarkable accuracy but still suffer from high inference latency due to heavy token processing. T…
RayMamba: Ray-Aligned Serialization for Long-Range 3D Object Detection
Cheng Lu, Mingqian Ji, Shanshan Zhang +2
Long-range 3D object detection remains challenging because LiDAR observations become highly sparse and fragmented in the far field, making reliable context modeling difficult for e…
