Title: Category Independent Object Proposals 

Abstract: 
In this work, we propose a category-independent method to produce a bag of 
regions 
and rank them, such that top-ranked regions are likely to be good 
segmentations of 
different objects. Our key objectives are completeness and diversity: every 
object 
should have at least one good proposed region, and a diverse set should be 
top- 
ranked. Our approach is to generate a set of segmentations by performing 
graph cuts 
based on a seed region and a learned affinity function. Then, the regions are 
ranked 
using structured learning based on various cues. Our experiments on BSDS and 
PASCAL VOC 2008 demonstrate our ability to find most objects within a small 
bag of 
proposed regions. 

I will also introduce upcoming work that leverages structured models to 
jointly 
represent objects and their parts across a range of categories. 

Be there! 
Thanks, 
Rajhans
