I am having problems setting up facetracker on windows,
Could some one please link to a tutorial or expain how to set up.
Thanks,
Cheers
The headers are deprecated, but still work in 2.4.8.
Ignore my previous version of this comment - I had version mismatch issues and that was stupid of me.
Hi,
I compiled the source files and libraries but when I'm executing the face_tracker, the compiler said that there's problem loading the model files even though they are in the right directory.
Here's my error log:
Loading tracker file: ../model/face2.tracker
Assertion failed: (s.is_open()), function Load, file src/lib/Tracker.cc, line 61.
Thanks,
Edward
Is there an entry-point function where I can get the facial landmarks and triangulation for a single image input instead of a video stream?
Thanks.

and it goes on like this. I have OpenCV 2.4.9 installed through the package manager.
I want to train their own models, but I found the code does not provide a training model of the code, I would like to know if I had misunderstood the algorithm or the code does not provide training code? You can provide training model code?
I am trying to use FaceTracker to estimate the pose of a human subject's head for a wide variety of poses.
I found that FaceTracker works better on certain people's heads than others, and does not not work for various head poses.
Is it possible to train the system on specific people or for certain poses?
Running the executable does not appear to do anything, as far as I can tell. Or at least if I only give it inputs/options according to the help info. When running it in the command window it gives no errors, just give a new input line. I can get it to output the help info.
Do I need to use the openframeworks wrapper to be able to get anything from it?
I'm using the python wrapper, and when I run any of the example programs, a segfault routinely occurs using the tracker.draw method. Any ideas on how to fix?
Hi,
I am new to openFrameworks and I am trying to build FaceTracker and ofxFaceTracker on windows using codeBlocks. Can you please tell me the steps to built it on windows.

Well, I am using windows 7 32bit.
Hi Kyle,
I need to modify the models to fit landmarks on children faces.
How can you compute the new face2.tracker files?
Bests,
Pablo Negri
I know this used to be a problem for people, but if I download the latest 0.9.0 ofx release, clone faceTracker and ofxCV into the addons, and use project generator to generate a new project with ofxCV, ofxFaceTracker and ofxOpenCv, i still get this error on compile. Those are all the steps necessary. I'm using visualStudio 2015
For what it's worth, I have no such problem on mac
Whoops... this issue was meant for ofxFaceTracker
1.in face_tracker.cc
line177:
changed to cv::VideoCapture camera(CV_CAP_ANY); if(!camera.isOpened()) return -1;
line188:
changed to camera.read(frame);
2.in io.h
replace <opencv/cv.h> with <opencv2/opencv.hpp>
3.in Makefile add link to -lopencv_videoio
and that's all.
I compiled it on my mac with opencv3.0 and g++5.3 and it works.
Hi all,
I've built and installed OpenCV 2.3.1, and I modified my FaceTracker Makefile per #3 as I am on Linux Mint 14. FaceTracker builds without issue, but nothing happens when I execute ./face_tracker

I would like to train a tracker based on my training data, so would you supply the code or lib of training part?
Hello
I am trying to install FaceTracker on Ubuntu 11.10. Following the instructions, the opencv was correctly installed.
When make FaceTracker, I got the following errors:
g++ -MM -MT src/lib/IO.o -MF src/lib/IO.d -Wextra -Wall -pedantic-errors -arch x86_64 -O3 -I/usr/local/include -Iinclude/ src/lib/IO.cc

If removing "-arch x86_64", there are many linking errors.
BTW, there seems to be a type in the readme.md file, "OPECV_PATH" may should be "OPENCV_PATH".
Thanks,
Peter

Hey, not really a bug.
I've found your and Jason's work pretty handy, so I built an Android app over it. Here is a link to the repo. Standalone apk also available. Hoping you could include it in the readme so it can help others.

Hi,
Does anyone know how the program handle the tracking when the face rotate? When we rotate the head and when we show our left/right profile, the program only displays points of the half face shown.
There is a function 'int CLM::GetViewIdx()' which returns the index of the head orientation (0 for front face, 1 for left profile, 2 for right profile). This index is used to read an array '_visi' which states what patch belongs or not to each orientation.
I've determined that this array is used to draw the points but I would like to know if it is also used for the tracking, if all patches are tracked but only the not hidden are displayed or if only the not hidden patches are tracked.
I know that something happens when my head orientation reaches a certain amount of yaw because there is a blip, little jumps between 2 drawings.
Thanks in advance for more explanations
Hi, I study the method of face tracking, and I get your code. I run the code on vs2013, when the face turns, the tracking failed and can't get the correct trail any more, should I modify some parameters to improve the problem?
Hope your reply. Thank you very much.
I want to try the face substitution but I need to include the forehead. In the tracker, I only see the mesh draw up until the eyebrows. What's the best way to solve this?
Hi,
I build FaceTracker on windows using CodeBloks, but it is giving me a segmentation fault. I debugged the program and found that segfault occur in PDM.cpp file at line 6.
1 void PDM::CalcShape3D(cv::Mat &s,cv::Mat &plocal)
2 {
3 assert((s.type() == CV_64F) && (plocal.type() == CV_64F));
4 assert((s.rows == _M.rows) && (s.cols = 1));
5 assert((plocal.rows == _E.cols) && (plocal.cols == 1));
6 s = _M + _V*plocal; return;
7 }
Can anybody help me.
Thanks
Hello, im having trouble with a high cpu perfomance in iOS. This is causing some delay`s in the face position. Anyone has a advice about that?
hi, is it likely to use fewer or more tracking points?
Hi,I wanna know what math is behind the algorithm, and would you please tell me which paper i the codes refer to?
Hi i tried to increase the performances due to some image operations i'm doing on the ROI defined by the points but without success (i'm using a 4core - 8 GB ram MBP - with a logitech C920 camera, 1080p at 30 frames-per-second (fps) and with the internal webcam too, and i'm getting over 100% cpu loading!!!), i tried to use gpu::Mat but isn't available for non nvidia cards (last generation of 17'' MBP has an ati card), for openCL in opencv i didn't find any example, my question is if i switch to the openframeworks version will it have a better performance? I didn't understand if the ofx versions uses opengl acceleration to do the face detection operation so before moving the whole project to it could you tell me if there is an improvement which will justify a move to the other version? Thank you in advance.
Attempt to compile the code on 10.8.4 gave me the following error: "ISO C++ does not support ‘long long’". Possibly my bad, fixed by adding "-Wno-long-long" to the list of CFLAGS.

What differences between the implementation on the FaceTracker and the implementation described on "Mastering OpenCV with Practical Computer Vision Projects. PACKT, Oct 2012. " by Saragih's?
There is some paper describing it?
Hi everyone,
i'm trying to print the coordinates from a specific point of the mask. How can i make this and how can i define the same point that i will have the coordinates? I'm a beginner on this, so if you could help me, it will be really nice.
Thanks
Hello, I am new to facetracker. I am recently doing a project to do gaze estimation, and I am using facetracker. I need the infomation of 3D head position w.r.t the camera, is Facetracker
offering that?
Thank you very much !
Is there any python version of this code?
The face tracking works really flawlessly but how can we detect which are the points that compose the eyes and the mouth? They are the ones inside the face shape perimeter but there is a way to get them precisely to define three polygons to create a mask (i'm trying to use the face to create a mask to apply to a texture to avoid the texture cover the eyes and the mouth area). thanx in advance. The idea is to fill the face area without filling the eyes and mouth polygons to generate the mask to be applied to a texture centered to the nose of the human.

Hi @kylemcdonald , could you explain how the deformation of face is handled, is there any reference paper?
Hello, I'm a graduate student from China. I has been studying this project for a month, but I don't know how to calculate the Jacob in the PDM.cpp. I don't know why Multiply the Rx, Ry, Rz by P_.
Looking forward to your reply. Thank you.
Not really an issue, so apologies if this is the wrong place for this.
I had a quick chat with Jason Saragih a while back and he seemed to think that this could potentially run OK on iOS.
Do you think this could be ported to AS3, or even Unity, since it leverages the GPU better, to run smoothly online?
