Title: Cascade systems for image segmentation
In this talk I will describe some of our recent work on learning systems
for image segmentation, that is, for automatic partition of the image into
meaningful regions. A common theme for much of this work is the idea of a
cascade: A sequence of decision-making stages, each trained to improve the
quality of the solutions obtained by the previous stage. I will focus on
two projects that rely, in different ways, on this basic idea. In one
project we re-rank multiple semantic image segmentations obtained from a
random field model (a very short cascade). The second project is on
building a much longer cascade, with tens of stages, for agglomerative
bottom-up merging of image regions. In both of these projects we can report
excellent results on benchmark data sets. This is joint work with Payman
Yadollahpour, Zhile Ren and Dhruv Batra.

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.
