Anqi Yang I'm software engineer at Google Cloud AI, working on multimedia generation and editing. I obtained my PhD from Carnegie Mellon University, advised by Prof. Aswin C. Sankaranarayanan. My thesis has been focused on pushing the frontier of mobile photography, by jointly design camera optics, sensor, and efficient deep restoration algorithms. I have won best paper award at ICCP in 2021 and Google Anita Borg Scholarship in 2016. Prior to that, I obtained my M.S. degree from the Robotics Institute at CMU and my M.S. thesis was on 3D object detection, segmentation, and classfication for dense 3D volumes. I obtained my B.Eng. degree from School of Software Engineering at Tongji University, working with Prof. Lin Zhang. I have spent wonderful summers as research interns at Google Labs, Samsung Research America, and University of Toronto. |

Designing Phase Masks for Under-Display Cameras
Anqi Yang, Eunhee Kang, Hyong-Euk Lee, Aswin C. Sankaranarayanan ICCV, 2023 project page / video / paper Key words: Under-display camera, diffractive optical elements, optimization Under-display cameras is an emerging type of camera that can image a scene through the openings of the display screens. This work proposes a novel design of diffractive optical elements that effectively renders the display screen invisible from the camera's perspective and keeps the display quality high at the same time. |

Designing Display Pixel Layouts for Under-Panel Cameras
Anqi Yang, Aswin C. Sankaranarayanan TPAMI / ICCP, 2021 (Best Paper Award) paper / video / press Key words: Joint optimization of camera and image restoration algorithms, camera ISP, deep learning-based deblurring, hardware prototype, wave optics The opening patterns on the display plays a crucial role in determining diffractive blur in under-panel cameras. This work proposes a suite of modifications to the display opening patterns that significantly increases the imaging quality of UDCs. |

SliceNets --- A Scalable Approach for Object Detection in 3D CT Scans
Anqi Yang, Feng Pan, Vishwanath Saragadam, Duy Dao, Zhuo Hui, Jen-Hao Chang, Aswin C. Sankaranarayanan WACV, 2021 paper / supp / video Key words: 3D object detection, segmentation, classification, leverage 2D to 3D This work addresses the challenging task of automated object detection in aviation screening with 3D computed tomography scans. We propose a slice-and-fuse framework, that slices 3D volumes into 2D slices, leverages efficient 2D detectors (e.g. RetinaNet), and fuse 2D predictions back to 3D. |
