Evaluation code roomlayout.m of cooperative_scene_parsing don't work on the output

Hi Yinyu:

I followed your guide to evaluate the results using code from [cooperative_scene_parsing](https://github.com/thusiyuan/cooperative_scene_parsing). With GT downloaded and some essential changes to path settings, the roomlayout.m runs successfully on the results predicted by your work.

However, the roomlayout.m outputs the same IoU of 0 on every sample. Here is sample 1 as an example:

I tried to turn on the visualization option looking to find the reason:

The predicted layout bounding box showed in the visualization above is nothing like the visualization with your code utils/visualize.py:

Is there anything I missed? If some more changes need to be made on the evaluation code from [cooperative_scene_parsing](https://github.com/thusiyuan/cooperative_scene_parsing), Is it possible to open-source your version of the final evaluation code?
