CVPR 2012 Day 1: Accidental Cameras, Large Jigsaws, and Cosegmentation

Today ended the first day of CVPR 2012 in Providence, RI.  And here's a quick recap:
  • On the administrative end of things, Deva Ramanan received an award for his contributions to the field as a new young CVPR researcher.  This is a new nomination-based award so be sure to vote for your favorite vision scientists next year!  Deva's work has truly influenced the field and he is well-known for being a co-author of the Felzenszwalb et al. DPM object detector, but since then he has pushed his ideas on part-based models to the next level.  Congratulations Deva, you are the type of researcher we should all strive to be.  
  • Secondly, it looks like CVPR 2015 will be in Boston.
  • Here are some noteworthy papers from the oral sessions of Day 1:

During the first oral session, Antonio Torralba gave an intriguing talk where he showed the world how accidental anti-pinhole and pin-speck cameras are "all around us."  In his presentation, he showed how a person walking in front of a window can be used to image the world outside of a window.  Additionally he showed a variant of image-based Van-Eck phreaking, where his technique could be used to view what is on a person's computer screen without having to look at the screen directly.

Andrew Gallagher gave a really great presentation on using computer vision to solve jigsaw puzzles, where not only are the pieces jumbled, but their orientation is unknown.  His algorithm was used to solve really really large puzzles, ones which are much larger than could be tackled by a human.

Gunhee Kim presented his newest work on co-segmentation.  He has been working on this for quite some time and if you are interested in segmentation in image collections, you should definitely check it out.
