OpenFace 2.2.0

Update of OpenFace to version 2.2.0, a number of bug fixes and library updates

Change log:

• Moving to C++17. This means that the code can only be build using C++17 compilers (e.g. g++ >8 and Visual Studio 2017, clang > 5), fixing related bugs - (#698, #629, #641)
• Removing an explicit dependency on boost (all the filesystem operations are performed using std::filesystem or boost::filesysteme). If boost is available it will used boost:filesystem, otherwise std::filesystem (this requires C++17).
• Visual Studio 2017 is now the main version for Visual Studio builds, VS 2015 is no longer supported
• Updating OpenCV to 4.1 version (#511)
• Fixing a bug with output images when using GUI (#694)
• Updating RAWImage - #609, so it can be initialized from System.Drawing.Bitmap directly
• Fixing overlap detection for multi face tracking: (#693)

OpenFace 2.1.0

• Removing TBB dependency. TBB can still be used, but is called through OpenCV (
  #241)
• Updating OpenBLAS version in 64-bit Windows builds (should lead to significant performance gains on that architecture)
• Allow specifying image output format (for both aligned images and visualized images). See wiki for more details
• Removing unused -q flag (#593)

OpenFace 2.0.6

A number of changes:

• Removed duplicated code and some C++ warnings
• Fixing snapshot function in HeadPoseLive
• C++ code cleanup (#533, #534)
• Adding a Visual Studio 2017 solution file
• Moving to C++ OpenCV convention
• Storing models in additional locations (see wiki and scripts (#553)

OpenFace 2.0.5

Changelog:

• Fixing a crash in OpenFaceOffline in processing images without any faces present (#488)
• Fixing a crash in OpenFaceDemo that was caused by memory management issues in wrapper between C# and C++ (#453)
• Fixing waitKey being called even when no output is visualized
• Removing AVX requirements on Windows code (will make it more compatible with some older machines)
• Fixing bbox directory issue (#539)

OpenFace 2.0.4

Changelog:

• Fixing a bug that sometimes caused a crash when the face left the screen
• Updating readme for OSX to do with memory issues in OpenBLAS
• Hard stop in CMake if Boost or OpenCV not found
• Fixing Haar detector copy in CMake (mentioned in #509)
• Getting ready for OpenCV 4.0 (thanks #511)
• Updating wiki on Mac installation and possible OpenBLAS issues

OpenFace 2.0.3

A lot of house-keeping: updating libraries and extra testing on various Ubuntu versions.

Changelog:

• Big re-org and cleanup of CMake (thanks aleh-arol - https://github.com/aleh-arol and severin-lemaignan - https://github.com/severin-lemaignan)
• CMake is now only for Ubuntu and OSX, while for windows builds use Visual Studio 2015
• Updating dlib to 19.13
  • Bringing up to recent build that has fewer clashes with OpenBLAS and boost
  • Now the code will require a separate build to link to on OS X and Ubuntu (this will allow users to re-use their own dlib builds and will increase stability)
• Instructions and testing for Ubuntu 14, 16, and 18
• Fixing boost and dlib clashes, that resulted in requiring a certain version of boost, now most versions of boost should work
• OpenBLAS include fixes with testing on Ubuntu 14.04, 16.04, 18.04, and OS X
• Some of the issues were caused by Ubuntu 14.04 openblas install not containing headers
• Some CNN util cleanup
• Cleaning up includes in Cpp interop code
• Bug fixes:
  • Really short executables using FeatureExtraction
• Option to process .webm files in the GUI

OpenFace 2.0.2

Mainly stability fixes:

• Cmake fixes and updates for OS X at Travis CI
• Threading issues resolved on certain versions of TBB on OS X and Ubuntu
• Fixing numerical stability bug with rotation matrices
• Fixing issue of OpenBLAS linking for OS X (default is to link to Accelerate)
• Addition of a docker image (thanks Edgar Aroutiounian)

OpenFace 2.0.1

Bug fixes:

• Fixing output video and image writing in Windows GUI
• Ability to us multi face tracking with x86 architectures (not running out of memory)
• Smaller memory footprint when using multiple CE-CLM models

Code cleanup:

• CEN response map computation path simplification

Features:

• Ability to tell OpenFace not to output aligned faces when detection unreliable

OpenFace 2.0.0

A lot of changes:

• A new facial landmark detection model - CE-CLM. Much more accurate model that is able to cope much better with profile faces
  • Training code for new models
  • Slightly slower than previous model, but previous models can still be used as well
• A new CNN based face detector (MTCNN) that can detect faces in much more difficult scenarios and even at profile faces!
• Both combined lead to better results on landmark detection, head pose estimation, gaze, and AUs
• GUI better support for multi-face images (correct visualization, output fixes with face id)
• GUI selection of face detector and landmark detector
• bug fix with memory allocation in visual C++ bindings
• Experimental evaluation on 300VW data
• Experimental evaluation on IJB-FL data
• Matlab hierarchical fitting has much cleaner and clearer code
• A lot of code optimizations
• Threading based input and output

OpenFace 1.0.0

Changelog:

• AU visualization module
• Stability fixes when AU or gaze models unavailable due to licensing
• Multi-PIE trained models added
• Bug fix with visualizing when faces are not detected in first frame
