The following posters (NIPS06 and ICML07) provide a good introduction to our work. Also, here are the slides from our ICML talk. And here is a video of the talk itself.

Code

If you are interested in obtaining our LSML Matlab code please contact us. The LSML code requires my basic toolbox, version 2.20 or higher. Updated as of Mar. 06, 2009, see readme.

Boundary Learning

The goal is simple: to learn edges and object boundaries from human labeled images while making few modeling assumptions. Some example training and testing images are given for a number of domains (click each icon to see some corresponding images, click again to enlarge further).

Code

Executables for the BEL edge detection are now available.

Behavior Recognition

This work has close ties to the Smart Vivarium, an ongoing project to automate the monitoring of animal health and welfare. The specific problems we are working on include: behavior recognition tracking abnormal activity detection large scale deployment

Papers

Piotr Dollár, Vincent Rabaud, Garrison Cottrell and Serge Belongie

The following poster provides a good introduction to our work.

Mouse Behavior & Facial Expression Datasets

The datasets, as described in Dollár et. al 2005, are available for download as a number of zip files. The video is encoded using the DivX codex, for help obtaining the codec click here.

Mouse Behavior [7 parts]:
      set00 | set01 | set02 | set03 | set04 | set05 | set06

Facial Expressions [4 parts]:
      set00 | set01 | set02 | set03

If you end up using the dataset or getting classification results, and you are willing to share your results, we would be grateful. Also, please cite the above paper if you report results in a publication.

Code

If you are interested in obtaining our code please contact us. You can see the documentation here, the code requires my basic toolbox, version 1.03. I will updated this code to be compatible with the more recent versions of my toolbox in the near future.
