To update the papers on your CVPR 2012 USB proceedings, please download the file USB_update.zip and unzip it from the root directory of your USB proceedings. Make sure that you have "flat" view turned off in your unzip software--you should only see listed (and unzip) the "data" folder. The zip file contains some updated main conference papers as well as additions to the workshops (including an updated table of contents) for a late workshop that missed the camera-ready deadline.
1) This is a second update, if you updated before this afternoon (Tuesday 6/19), you should grab the latest version.
2) the download (~60MB) will be a slow at the conference center.
