SDNet: LiDAR Semantic Scene Completion with Sparse-Dense Fusion and Input-Aware Label Refinement

AAAI 2026technical

LiDAR Semantic Scene Completion (SSC) in autonomous driving requires predicting both dense occupancy and semantic labels from sparse input point cloud. Existing methods typically adopt cascaded architecture for feature dilation and semantic abstraction, which blurs distinctive geometric patterns and

Privacy-Preserving V2X Collaborative Perception Integrating Unknown Collaborators

AAAI 2025technical

Vehicle-to-everything (V2X) collaborative perception has recently gained increasing attention in autonomous driving due to its ability to enhance scene understanding by integrating information from other collaborators, e.g. vehicles or infrastructure. Existing algorithms usually share deep features…

RayFusion: Ray Fusion Enhanced Collaborative Visual Perception

NeurIPS 2025poster

Collaborative visual perception methods have gained widespread attention in the autonomous driving community in recent years due to their ability to address sensor limitation problems. However, the absence of explicit depth information often makes it difficult for camera-based perception systems, e.…

SCKD: Semi-Supervised Cross-Modality Knowledge Distillation for 4D Radar Object Detection

AAAI 2025technical

3D object detection is one of the fundamental perception tasks for autonomous vehicles. Fulfilling such a task with a 4D millimeter-wave radar is very attractive since the sensor is able to acquire 3D point clouds similar to Lidar while maintaining robust measurements under adverse weather. However,…

Exploring Base-Class Suppression with Prior Guidance for Bias-Free One-Shot Object Detection

AAAI 2024technical

One-shot object detection (OSOD) aims to detect all object instances towards the given category specified by a query image. Most existing studies in OSOD endeavor to establish effective cross-image correlation with limited query information, however, ignoring the problems of the model bias towards t…

A Two-Stage Based Social Preference Recognition in Multi-Agent Autonomous Driving System

IROS 2023poster

Multi-Agent Reinforcement Learning (MARL) has become a promising solution for constructing a multi-agent autonomous driving system (MADS) in complex and dense scenarios. But most methods consider agents acting selfishly, which leads to conflict behaviors. Some existing works incorporate the concept…

Think Twice Before Detecting GAN-Generated Fake Images From Their Spectral Domain Imprints

CVPR 2022poster

Accurate detection of the fake but photorealistic images is one of the most challenging tasks to address social, biometrics security and privacy related concerns in our community. Earlier research has underlined the existence of spectral domain artifacts in fake images generated by powerful generati…

Infant Footprint Recognition

ICCV 2017poster

Infant recognition has received increasing attention in recent years in many applications, such as tracking child vaccination and identifying missing children. Due to the lack of efficient identification methods for infants and newborns, the current methods of infant recognition rely on identificati…
