Light Field Vision

Speaker: Hajime Nagahara

Time: Mar 18, 4:00pm - 5:00pm.

Location: Lecture hall, Administration Center


Light field is group of rays coming from an environment. Light field imaging is getting popular, since some light field cameras are available in a market. However, Light field is usually for visualization application, such as refocusing or viewpoint free displaying. We propose light field vision, a new approach that uses light field cameras in research of visual recognition. Light field has rich 4D function I(x, y, u, v), while regular camera only captures to 2D sub-dimensional image (x, y) of it.  We try to solve the problems that have been difficult to solve in the area of computer vision based on normal images.

In this talk, we propose the light field vision concept and show some examples; transparent object classification, segmentation, and dynamic object segmentation etc.
