A Dual-Source Approach for 3D Pose Estimation from a Single Image

Introduction

The code package provides a tool for estimating 3D human pose from a single image. If you use this code for research purposes, please cite the following paper in any resulting publication:

Hashim Yasin, Umar Iqbal, Björn Krüger, Andreas Weber, Juergen Gall
A Dual-Source Approach for 3D Pose Estimation from a Single Image
IEEE Conference on Computer Vision and Pattern Recognition (CVPR) 2016.

The code is tested on Ubuntu 14.04 (64bit) with MATLAB (2016a).

#Instructions

1. PROVIDED
   Within this Release, we provide

   • the pre-normalized 3D pose database for Human3.6M
   • pre-trained random forests for 2D pose estimation

2. REQUIREMENTS
   2.1. LIBRARIES

• OpenCV
• Boost-1.55
• Gflags
• GLog compiled with Gflags

If the libraries are installed locally, please set 'CUSTOM_LIBRARY_PATH' in '../MEX/src/CMakeLists.txt' to your corresponding directory containing the glog, gflags folders. In '../MEX/src/cmake/Modules' scripts are provied to find your local glog and gflags installation.

Also please make sure that all local libraries are specified in your LD_LIBRARY_PATH and in your PATH variables.

2.2. TOOLBOXES
Matlab's optimization toolbox.

2.3. DATASET
Please get the Human36M Dataset and extract it to '../Human36M/code-v1.1/Release-v1.1' or any other location. If Human36M is located somewhere else, the path has to be adapted. See 6. for more information.

3. Run the script 'get_data.sh' to download the required models and pre-normalized database of 3D poses.

4. Switch to the 'code' folder to run any function.

5. COMPILATION
   To compile and install the binaries, please run 'installBinaries.m'. This script automatically runs cmake to build the neccecasry C++ implementations. For some Matlab installations, this results in some undefined reference errors. In that case, please switch to '../MEX/src/build' and run the following commands manually from your terminal

   • $ cmake -G "Unix Makefiles" ../
   • $ make

6. CONFIGURATION
   6.1. Adjust Parameters Open 'Initialize.m' located in the 'code' folder. Line 9:
   If necessary, adjust the path for the Human36M code

   Line 16 and following:
   In some cases, matlab has problems executing the binaries, because there are conflicts with matlab's provided openCV libraries. If this is the case, please adjust the 'OPENCV_LIBRARY_PATH' and the 'OPENCV_INCLUDE_PATH'

   Line 48 and following:
   Adapt configuration parameters for pose estimation like location of ground truth files or save paths for (temporary) estimation results:

   TDPose_ConfigPath:
   /some/location/3D_Pose_Estimation/MEX/src/regressors
   TDPose_ExperimentName:
   Folder contained in TDPose_ConfigPath
   TDPose_TestImageLocation:
   Path, where the test image are located
   TDPose_NTrees:
   Number of trees that are used in each forest
   TDPose_TrainFile:
   Path to the train annotation file for the dataset
   TDPose_TmpFileSavePath:
   Path where to save temporary data
   TDPose_TmpSaveResults:
   Path where to save (temporary) results
   TDPose_VisualizeResults:
   1, if results should be visualized
   TDPose_PauseAfterResult:
   1, if estimation should be paused
   TDPose_DeleteFilesAfterEstimation:
   delete all estimation files

Line 85:
You can specify, how many iterations you want to perform.

7. RUNNING THE CODE

You can either call 'RUN_Complete.m' to perform 3D Pose Estimation onthe whole dataset once or call 'RUN_Iterated.m' to performe 3D Pose Estimation for each single image of the dataset.

Ideally the approach requires roughly 100GBs of RAM to load 3D pose databases for the retrievel of K-NNs. However, in this release we have modified the code to fit in 32GBs of RAM. Therefore, the run-time will be different as compared to  the one reported in the paper.  

8. FUTURE RELEASE
In the future we will also add support for HumanEva dataset
