[Colloquium] REMINDER: 5/12 Research at TTIC: Greg Shakhnarovich, TTIC

[Mary Marre via Colloquium]

When:     Friday, May 12th at noon



Where:    TTIC, 6045 S Kenwood Avenue, 5th Floor, Room 526



Who:       Greg Shakhnarovich, TTIC



Title:       Image Colorization and Its Role in Visual Learning

Abstract:
I will present our recent and ongoing work on fully automatic image
colorization. Our approach exploits both low-level and semantic
representations during colorization.  As many scene elements naturally
appear according to multimodal color distributions, we train our model to
predict per-pixel color histograms. Our system achieves state-of-the-art
results under a variety of metrics. Moreover, it provides a vehicle to
explore the role the colorization task can play as a proxy for visual
understanding, providing a self-supervision mechanism for learning
representations. I will describe the application of our self-supervised
network in several contexts, such as classification and semantic
segmentation. On these tasks, we present results that are state-of-the-art
among methods not using massive supervised pre-training.

Joint work with Gustav Larsson and Michael Maire.

*Research at TTIC Seminar Series*

TTIC is hosting a weekly seminar series presenting the research currently
underway at the Institute. Every week a different TTIC faculty member will
present their research.  The lectures are intended both for students
seeking research topics and adviser, and for the general TTIC and
University of Chicago communities interested in hearing what their
colleagues are up to.

To receive announcements about the seminar series, please subscribe to the
mailing list: https://groups.google.com/a/ttic.edu/group/talks/subscribe
