#SceneNet

All the necessary source code for SceneNet SceneNet: Understanding Real World Indoor Scenes with Synthetic Data will be available here soon.

#Updates

This code enables depth and annotation rendering given a 3D model and trajectory. We provide a sample 3D model in the data folder and a trajectory in data/room_89_simple_data folder. More details will be updated soon. Things to do

Simulated Annealing
RGB Rendering to be merged with the code
Releasing Trajectories
Converting Depth to DHA format
Emphasise on Negative Focal Length

#Dependencies

[Pangolin] (https://github.com/ankurhanda/Pangolin-local) Local copy of https://github.com/stevenlovegrove/Pangolin
CVD (It will not be a dependency any more in future!)
TooN (It will be replaced by Eigen3 in future!)
ImageUtilities
SceneGraphRendering (will be merged within soon!)
OpenCV/OpenCV2
libnoise (from synaptic)

#Build

mkdir build
cd build
cmake .. -DCUDA_PROPAGATE_HOST_FLAGS=0
make -j8

#Demo in your build, run

./opengl_depth_rendering ../data/room_89_simple.obj

You should have annotated images in the folder data/room_89_simple_data that should look like these

#Conversion from SUN RGB-D/NYUv2 37/40 Labels

Get the 40 class mapping for NYUv2 from http://www.cs.berkeley.edu/~sgupta/cvpr13/. SUN RGB-D already provide the 37 class mapping in their meta-data files.

Label name and number are from SUN RGB-D/ NYUv2. Their corresponding SceneNet/Eigen et al. mapping is in the last column.

\caption{Results on NYUv2 test data for 13 semantic classes. We see a similar pattern here --- adding synthetic data helps immensely in improving the performance of nearly all functional categories of objects using DHA as input channels. As expected, accuracy on \textit{books}, \textit{painting}, \textit{tv}, and \textit{windows}, is compromised highlighting that the role of depth as a modality to segment these objects is limited. Note that we recomputed the accuracies of \cite{Eigen:etal:ICCV2015} using their publicly available annotations of 320$\times$240 and resizing them to 224$\times$224. Hermans \textit{et al.} \cite{Hermans:etal:ICRA2014} use ``\textit{Decoration}" and ``\textit{Bookshelf}" instead of \textit{painting} and \textit{books} as the other two classes. Therefore, they are not directly comparable. Also, their annotations are not publicly available but we have still added their results in the table. Note that they use 640$\times$480. Poor performance of SceneNet-DHA and SceneNet-DO-DHA on \textit{tv} and \textit{windows} is mainly due to limited training data for these classes in SceneNet.}
