1 # Facial Landmarks for Cubism
3 A library that extracts facial landmarks from a webcam feed (computed by [OpenSeeFace](https://github.com/emilianavt/OpenSeeFace)) and converts them
4 into Live2D® Cubism SDK parameters.
6 *Disclaimer: This library is designed for use with the Live2D® Cubism SDK.
7 It is not part of the SDK itself, and is not affiliated in any way with Live2D
8 Inc. The Live2D® Cubism SDK belongs solely to Live2D Inc. You will need to
9 agree to Live2D Inc.'s license agreements to use the Live2D® Cubism SDK.*

18 ## Old version using dlib
19 The old version using dlib is no longer actively maintained, but if
20 you want to use it, you can get it on the [dlib-stable branch](https://github.com/adrianiainlam/facial-landmarks-for-cubism/tree/dlib-stable).
22 ## Spin-off: Mouse Tracking for Cubism
24 An alternative version using mouse cursor tracking and audio based lip
25 syncing instead of face tracking is available at
26 <https://github.com/adrianiainlam/mouse-tracker-for-cubism>.
28 The main advantage is a much lower CPU load.
30 ## Supporting environments
32 This library was developed and tested only on Ubuntu 18.04 using GCC 7.5.0.
34 Currently it only supports Unix-like environments, as I am using
35 `<sys/socket.h>` etc to communicate with OpenSeeFace. If there is demand
36 for it, I can try to make it work on Windows as well (contributions
39 The library should only require C++11. The Cubism
40 SDK requires C++14. I have made use of one C++17 library (`<filesystem>`)
41 in the example program, but it should be straightforward to change this
42 if you don't have C++17 support.
46 1. Download OpenSeeFace from <https://github.com/emilianavt/OpenSeeFace>,
47 refer to its documentation and install its dependencies.
49 Note: I have forked OSF and added a small feature (flipping the webcam
50 feed horizontally like a mirror). If you want, you can clone my fork
51 instead: <https://github.com/adrianiainlam/OpenSeeFace>.
53 2. Install dependencies.
55 You will require a recent C/C++ compiler, `make`, `patch`, and CMake >= 3.16. To compile the example
56 program you will also require the OpenGL library (and its dev headers)
57 among other libraries required for the example program. The libraries I
58 had to install on Ubuntu 18.04 (this list may not be exhaustive) are:
60 libgl1-mesa-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev libglu1-mesa-dev
62 3. Clone this repository
64 git clone https://github.com/adrianiainlam/facial-landmarks-for-cubism.git
66 4. To build the library only: (Skip this step if you want to build the example
67 program. It will be done automatically.)
69 cd <path of the git repo>
72 To build the example program:
74 5. Download "Cubism 4 SDK for Native R2" from the Live2D website:
75 <https://www.live2d.com/en/download/cubism-sdk/download-native/>.
77 Extract the archive -- put the "CubismSdkForNative-4-r.2" folder under
78 the "example" folder of this repo.
80 Note: The Cubism SDK is the property of Live2D and is not part of this
81 project. You must agree to Live2D's license agreements to use it.
84 "example/CubismSdkForNative-4-r.2/Samples/OpenGL/thirdParty/scripts"
89 7. Go back to the "example" directory and run
93 8. Now try running the example program.
95 First, (in a separate terminal) go to where you have downloaded
98 ./python3 ./facetracker.py -v 4 --model 3 -M
100 The `-M` option is currently available only on my OSF fork.
102 I tried models 3 and 4, and I think both work reasonably well.
103 Please feel free to explore other options provided by OSF.
105 Back to the original terminal, from the "example" directory:
107 cd ./demo_build/build/make_gcc/bin/Demo/
111 ## Command-line arguments for the example program
113 Most command-line arguments are to control the Cubism side of the program.
114 Only one argument (`--config`) is used to specify the configuration file
115 for the Facial Landmarks for Cubism library.
117 * `--window-width`, `-W`: Specify the window width
118 * `--window-height`, `-H`: Specify the window height
119 * `--window-title`, `-t`: Specify the window title
120 * `--root-dir`, `-d`: The directory at which the "Resources" folder will
121 be found. This is where the model data will be located.
122 * `--scale-factor`, `-f`: How the model should be scaled
123 * `--translate-x`, `-x`: Horizontal translation of the model within the
125 * `--translate-y`, `-y`: Vertical translation of the model within the window
126 * `--model`, `-m`: Name of the model to be used. This must be located inside
127 the "Resources" folder.
128 * `--old-param-id`, `-o`: If set to 1, translate new (Cubism 3+) parameter
129 IDs to old (Cubism 2.1) IDs. This is necessary, for example, for
130 [the Chitose model available from Live2D](https://www.live2d.com/en/download/sample-data/).
131 * `--config`, `-c`: Path to the configuration file for the Facial Landmarks
132 for Cubism library. See below for more details.
135 ## Configuration file
137 Due to the differences in hardware and differences in each person's face,
138 I have decided to make pretty much every parameter tweakable. The file
139 "config.txt" lists and documents all parameters and their default values.
140 You can change the values there and pass it to the example program using
141 the `-c` argument. If using the library directly, the path to this file
142 should be passed to the constructor (or pass an empty string to use
147 The library itself is provided under the MIT license. By "the library itself"
148 I refer to the following files that I have provided under this repo:
150 * src/facial_landmark_detector.cpp
152 * include/facial_landmark_detector.h
153 * and if you decide to build the binary for the library, the resulting
154 binary file (typically build/libFacialLandmarksForCubism.a)
156 The license text can be found in LICENSE-MIT.txt, and also at the top of
157 the .cpp and .h files.
159 The example program is a patched version of the sample program provided
160 by Live2D (because there's really no point in reinventing the wheel),
161 and as such, as per the licensing restrictions by Live2D, is still the
164 The patch file (example/demo.patch) contains lines showing additions by
165 me, as well as deleted lines and unchanged lines for context. The deleted
166 and unchanged lines are obviously still owned by Live2D. For my additions,
167 where substantial enough for me to claim ownership, I release them under
168 the Do What the Fuck You Want to Public License, version 2. The full license
169 text can be found in LICENSE-WTFPL.txt.
171 All other files not mentioned above that I have provided in this repo
172 (i.e. not downloaded and placed here by you), *excluding* the two license
173 documents and files generated by Git, are also released under the Do What
174 the Fuck You Want to Public License, version 2, whose full license text
175 can be found in LICENSE-WTFPL.txt.
177 In order to use example program, or in any other way use this library
178 with the Live2D® Cubism SDK, you must agree to the license by Live2D Inc.

182 This is not a license requirement, but if you find my library useful,
183 I'd love to hear from you! Send me an email at spam(at)adrianiainlam.tk --
184 replacing "spam" with the name of this repo :).
188 Contributions welcome! This is only a hobby weekend project so I don't
189 really have many environments / faces to test it on. Feel free to submit
190 issues or pull requests on GitHub, or send questions or patches to me
191 (see my email address above) if you prefer email. Thanks :)
