Faculty Candidate Seminar: Multi-perspective computational
imaging and its applications in 3D reconstruction
February 3, 2017
Dr. Jinwei Ye, Senior Scientist, Canon USA. Inc.
January 30, 2017 3:00 pm to 4:00 pm, 145/149 EE Building
Refreshments starting at 2:45 pm
Abstract:
Traditional single perspective camera has long served as the workhorse in compute
vision and graphics.
However, the essential depth information of a scene is discarded in its image due
to perspective flattening.
In contrast, a multi-perspective camera combines light rays collected from different
viewpoints. Such
capability can benefit a broad class of applications, ranging from scene understanding
to 3D
reconstruction. In this talk, I will present the designing, modeling, and constructing
of multi-perspective
computational imaging systems and showcase their applications in depth recovery and
3D reconstruction.
First, I will show a special type of multi-perspective camera, the crossed-slit camera,
and demonstrate its
advantages in acquiring 3D information. Then, I will present several multi-perspective
illumination systems
and show their applications in recovering challenging invisible objects (e.g., mirror-like
objects, transparent
fluids and gas flows). Finally, I will end my talk with a brief discussion on key
challenges and future
opportunities in multi-perspective computational imaging.
Bio:
Dr. Jinwei Ye is a senior scientist in the Innovation Center of Canon, USA. Prior
to that, she was a post-
doctoral researcher in the US Army Research Laboratory (ARL). She received her Ph.D.
in Computer
Science from the ¾Å¾Å¸£ÀûÍø of Delaware in 2014 and B.E. in Electrical Engineering
from Huazhong
¾Å¾Å¸£ÀûÍø of Science and Technology, China in 2009. Dr. Ye's research spans the fields
of computer vision,
computational photography and computer graphics. In particular, she is interested
in the co-design of
cameras, illuminations and computational algorithms for efficient 3D visual information
acquisition and
processing. Jinwei's works have been published in premier conferences such as CVPR,
ECCV and ICCV.
