DESCRIPTION:High Dynamic Range (HDR) imaging captures a wider luminance ra
 nge\, enhancing visual realism beyond standard imaging constraints. We pre
 sent deep learning-based approaches for HDR reconstruction\, generation\, 
 and display. For reconstruction\, we leverage implicit neural fields with 
 a physics-driven camera model to recover HDR content from multi-focus\, mu
 lti-exposure image stacks\, effectively handling misalignment and depth va
 riations. Additionally\, we utilize 3D Gaussian Splatting to reconstruct H
 DR radiance fields\, enabling real-time\, depth-of-field cinematic renderi
 ng. In HDR generation\, we introduce an unsupervised generative model (Glo
 wGAN) that learns HDR distributions from LDR images via exposure-consisten
 t projections\, alongside LEDiff\, a diffusion-based framework that fine-t
 unes Stable Diffusion on a limited HDR dataset for HDR synthesis and LDR-t
 o-HDR restoration through latent space fusion. For display\, we propose a 
 self-supervised tone mapping approach that optimizes contrast perception a
 t test time\, surpassing traditional methods in perceptual fidelity.\n\nBi
 o: Chao Wang received his Ph.D. from the Max Planck Institute for Informat
 ics\, where he was advised by Prof. Karol Myszkowski and Prof. Hans-Peter 
 Seidel. He also worked closely with Prof. Ana Serrano and Dr. Thomas Leimk
 ühler. Before joining MPI\, he earned an M.S. degree from Peking Universi
 ty and a B.S. degree from the University of Electronic Science and Technol
 ogy of China. Chao has gained research experience across academia and indu
 stry. He served as a Research Scientist Intern at Adobe’s Next Cam Lab\,
  collaborating with Marc Levoy and Cecilia Zhang\, and previously worked a
 s an Algorithm Research Scientist Intern at Tencent’s Robotics X Lab. He
  was also a visiting researcher at the University of Calgary.\n\nJoin Zoom
