Feiran Wang

Hi, I'm Feiran, a third-year PhD student in computer vision at Illinois Tech, advised by Professor Yan Yan. I'm currently a Research Intern at the Bosch Center for Artificial Intelligence (BCAI), mentored by Dr. Xiaoqi Wang.

My research centers on Spatial Intelligence: powering agents to reason about real-world environments, predict spatiotemporal dynamics, and render future states of the world. My philosophy is that explicit 3D representation could be the foundation of a world model where agents and humans can interact with each other. My research spans 3D reconstruction, video generation, Vision-Language Models, Agentic Harness and Self-Evolving Agents.

I hold an M.S. from University of Illinois Urbana-Champaign, advised by Professor David Forsyth, and a B.S. from Shanghai University, advised by Professor Xiaoqiang Li. Previously, I had academic visits at the University of Michigan, and University of Illinois Chicago.

Bosch · Research Internship
2026 May to August · United States

Long-tail dataset generation for autonomous driving. Focusing on 3D-based data synthesis and scene editing to improve perception model robustness in rare and safety-critical scenarios.

Publication

RayMap3R
RayMap3R: Inference-Time RayMap for Dynamic 3D Reconstruction
ECCV, 2026

We revisit and observe that RayMap-based predictions exhibit inherent static scene bias and propose RayMap3R, a training-free streaming framework for dynamic scene reconstruction.

LIST3R
LIST3R: Long-sequence Instance-aware 3D Reconstruction
Jing Gao, Wei Wang, Feiran Wang, Yan Yan
Preprint

We present LIST3R, an instance-aware framework for long-sequence 3D reconstruction inspired by the way humans organize spatial memory around stable and recognizable objects.

CIF
Consistent Instance Field for Dynamic Scene Understanding
CVPR, 2026

CIF formulates a continuous probabilistic field over object existence and identity in space-time, enabling consistent instance representations across views for dynamic scene understanding.

GPF
From Particles to Fields: Reframing Photon Mapping with Continuous Gaussian Photon Fields
Preprint

GPF reformulates photon mapping as a continuous radiance field of 3D Gaussian primitives, achieving photon-level accuracy for global illumination with greatly reduced computation.

CogniMap3D
CogniMap3D: Cognitive 3D Mapping and Rapid Retrieval
ICLR, 2026

We present CogniMap3D, a bioinspired framework that maintains a persistent memory bank of static scenes, enabling efficient spatial knowledge storage and rapid retrieval.

X-Field
X-Field: A Physically Informed Representation for 3D X-ray Reconstruction
NeurIPS, 2025 (Spotlight)

Rooted in the X-ray imaging process, X-Field presents a representation specifically for high-quality X-ray Novel View Synthesis and CT Reconstruction.

ZECO
ZECO: ZeroFusion Guided 3D MRI Conditional Generation
MVA, 2025 (Oral)

To mitigate medical data scarcity, ZECO synthesizes high-quality 3D MRI images across various modalities, conditioned on segmentation masks.

PCCN-RE
PCCN-RE: Point Cloud Colourisation Network Based on Relevance Embedding
Feiran Wang, Jitao Liu, Xiaoqiang Li
IET Computer Vision, 2022

Point clouds captured by LiDAR are often colorless; PCCN-RE enables high-quality colorization with a relevance embedding module built on a Conditional GAN.

Scientific Project

Neuron
A Unified Framework for Unsupervised Sparse-to-dense Brain Image Generation and Neural Circuit Reconstruction

Understanding morphology and distribution of neurons remains a significant challenge in modern neuroscience. We aim to develop a unified framework for sparse-to-dense neural generation and unsupervised segmentation, providing deeper insights into neural activity and connectivity.
