Extreme 3D Face Reconstruction: Looking Past Occlusions

Please, note that the main part of the code has been released, though we are still testing it to fix possible glitches. Thank you.

Python and C++ code for realistic 3D face modeling from single image using our shape and detail regression networks

This page contains end-to-end demo code that estimates the 3D facial shape with realistic details directly from an unconstrained 2D face image. For a given input image, it produces standard ply files of the 3D face shape. It accompanies the deep networks described in our paper [1] and [2]. The occlusion recovery code, however, will be published in a future release. We also include demo code and data presented in [1].

Teaser

Dependencies

Library requirements

The code has been tested on Linux only. On Linux you can rely on the default version of python, installing all the packages needed from the package manager or on Anaconda Python and install required packages through conda. A bit more effort is required to install caffé, dlib, and libhdf5.

Data requirements

Before running the code, please, make sure to have all the required data in the following specific folder:

  • Download our Bump-CNN and move the CNN model (1 file: ckpt_109_grad.pth.tar) into the CNN folder
  • Download our CNN and move the CNN model (3 files: 3dmm_cnn_resnet_101.caffemodel,deploy_network.prototxt,mean.binaryproto) into the CNN folder
  • Download the Basel Face Model and move 01_MorphableModel.mat into the 3DMM_model folder
  • Acquire 3DDFA Expression Model, run its code to generate Model_Expression.mat and move this file the 3DMM_model folder
  • Go into 3DMM_model folder. Run the script python trimBaselFace.py. This should output 2 files BaselFaceModel_mod.mat and BaselFaceModel_mod.h5.
  • Download dlib face prediction model and move the .dat file into the dlib_model folder.

Note that we modified the model files from the 3DMM-CNN paper. Therefore, if you generated these files before, you need to re-create them for this code.

Installation (C++ code)

  • Install cmake:
	apt-get install cmake
  • Install opencv (2.4.6 or higher is recommended):
	(http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html)
  • Install libboost (1.5 or higher is recommended):
	apt-get install libboost-all-dev
  • Install OpenGL, freeglut, and glew
	sudo apt-get install freeglut3-dev
	sudo apt-get install libglew-dev
  • Install libhdf5-dev library
	sudo apt-get install libhdf5-dev
  • Install Dlib C++ library
	(http://dlib.net/)
  • Update Dlib directory paths (DLIB_INCLUDE_DIR and DLIB_LIB_DIR) in CMakeLists.txt
  • Make build directory (temporary). Make & install to bin folder
	mkdir build
	cd build
	cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=../bin ..
	make
	make install

This code should generate TestBump in bin folder

Usage

3D face modeling with realistic details from a set of input images

  • Go into demoCode folder. The demo script can be used from the command line with the following syntax:
$ Usage: python testBatchModel.py <inputList> <outputDir>

where the parameters are the following:

  • <inputList> is a text file containing the paths to each of the input images, one in each line.
  • <outputDir> is the path to the output directory, where ply files are stored.

An example for <inputList> is demoCode/testImages.txt

../data/test/03f245cb652c103e1928b1b27028fadd--smith-glasses-too-faced.jpg
../data/test/20140420_011855_News1-Apr-25.jpg
....

The output 3D models will be <outputDir>/<imageName>_<postfix>.ply with <postfix> = <modelType>_<poseType>. <modelType> can be "foundation", "withBump" (before soft-symmetry),"sparseFull" (soft-symmetry on the sparse mesh), and "final". <poseType> can be "frontal" or "aligned" (based on the estimated pose). The final 3D shape has <postfix> as "final_frontal".

The PLY files can be displayed using standard off-the-shelf 3D (ply file) visualization software such as MeshLab.

Note that our occlusion recovery code is not included in this release.

Demo code and data in our paper

  • Go into demoCode folder. The demo script can be used from the command line with the following syntax:
$ Usage: ./testPaperResults.sh
