To install openface, follow the below instructions:

To download the trained model:

  • sh models/get-models.sh

Those installation steps don't work for me on mac. "import dlib" fails, and "import openface" fails with opencv dependency.

Hey, is there any way we can get only the eyes images after the align?
Example:
aaron_guiel_0001_l
Thank you

Also, those installation steps don't work on windows. Maybe only support ubantu linux.

I think you can try to use anaconda, and then follow the steps here to install dlib, openface.(https://github.com/samotiian/Installing_openface_with_anaconda)
And for those who can't install opencv library correctly, you can also use conda to install it by type the below command in your terminal:
conda install -c https://conda.binstar.org/menpo opencv3
I hope its helpful.

The problem that I'm experiencing is different:

     24 # Run the HOG face detector on the image data
---> 25 detected_faces = face_detector(image, 1)
     26 
     27 print("Found {} faces in the image file {}".format(len(detected_faces), file_name))

RuntimeError: Unsupported image type, must be 8bit gray or RGB image.

I've tried all that is suggested in ageitgey/face_recognition#21
,but couldn't fix it. Please help!
Thank you!

@karthikveermani it's better if you use Ubuntu for doing this project as in case of mac there are different, more complicated ways to install the dependencies.. I have a mac but i run ubuntu on vm

file_name = sys.argv[1] has been written two times. It only needs to be written once.

I am getting the error AttributeError: module 'openface' has no attribute 'AlignDlib'. Am I missing something here?
import openface works fine.

i have the same error as @nishantkumar1292 : AttributeError: module 'openface' has no attribute 'AlignDlib'
All the steps work fine but when i run the script i got this error.
I am on ubuntu

I also had the "AttributeError: module 'openface' has no attribute 'AlignDlib'" error.
I installed python 3.4 and made sure all the modules/packages needed for the openface are versions in the required range (requirements.txt), and now it works!

I keep getting the following error:

Traceback (most recent call last): File "detect_face_alignment.py", line 15, in <module> detected = frontal_face_detector(img, 1) RuntimeError: Expected writable numpy.ndarray with shape set.

My code matches what is written here. Any ideas as to what I could be doing wrong?

Hi @asthanakarishma, looks like you are also doing something else. Can you share your complete code here.

Hi,
I have a small problem and I have no idea how to solve it in a right way (actually I have, but not sure that it is correct).
Let's suppose that we need to get landmarks from the aligned image. To do that we need:

  1. find a face on the image using face_detector
  2. align image using face_aligner
  3. find face on aligned image using face_detector again
  4. obtain the landmarks with usage face_pose_predictor

And here the problem: face_detector returns empty dlib.rectangles object on aligned image. So, I am not able to use face_pose_predictor because it requires face rectangle which is absent.

My idea is that I can omit step #3 and use face_pose_predictor on aligned image without searching for the face on it. And the bounding box for landmarks detection specify as [[0, 0], [aligned_height, aligned_width]]. But I'm not confident that this is a correct way to deal with the problem.

There's something I don't understand:
In your article, it says "here’s the code for transforming the image using those landmarks.“.
but from my understanding of the source code. the transforming doesn't use any landmarks at all?
can you explain how?
