Face-api.js: Missing Age and Gender detection

[MakarandKate]

Please add age and gender detection in lib

Sounds like a reasonable extension. Any links to repos with pretrained models would be helpful.

You can take a look at this https://github.com/bharathvaj1995/gender-detection-tensorflowjs
and the pretrained here https://s3.ap-south-1.amazonaws.com/arunponnusamy/pre-trained-weights/gender_detection.model However, I'm using this works https://github.com/oarriaga/face_classification and the results so far is pretty good. I would have provided the codes for that.

How could I perform transfer learning and train, over which models files, to add gender / age recognition. If I had an already trained model, how could I "plug" it into the API?

[justadudewhohacks]

Not sure if I understood correctly.

If you want to train your own model with transfer learning, I would actually try to use the face landmark model and replace the fully connected layer with an own one that outputs male / female.

Regarding the second question: What kind of model do you have? A tensorflow.js web model? If it is a plain tensorflow model you can probably convert it to a web model using the tfjs-converter tool.

Sorry, I'm new to TensorFlow. I'd need the outputs of face classification
to include gender and approximate age. I currently don't know how to do it,
not even in a way that would result in a model compatible with this API.

Sorry again. If I had a couple of TensoFlow.js Web models for gender / age classification of faces, could I "pipeline" them with each detected face from this API, maybe using single image recognition (not object detection), augmenting the face output predictions with these attributes?

[justadudewhohacks]

Yes, I mean the input of such a model would probably be the image of a face right? So you basically use face-api.js to detect and extract faces from an image and pass these into your network. Does that answer your question?

[ghost]

Yes, and thanks! I've just saw it was an enhancement request and tought it
could be part of the API itself. Again, sorry for my lack of knowledge.

Thanks! It will be of great help.

Yeah, age and gender recognition is not implemented yet, I am collecting some resources at the moment.

[buggles333]

+1 from me, gender detection would be a great addition

[justadudewhohacks]

Age, gender, ethnicity recognition is next on my list. Fortunately there is lot's of data available. Can't promise any ETA yet.

[examityharikrishna]

That's great!

Hi,
Thank you so much for the library, great work! I also find the age and gender recognition quite interesting and had seen that you had already started the implementation in a branch. Can you already give an estimate when you will release it?

[justadudewhohacks]

I am working on it a little bit more actively currently. Can't give any estimations yet when to I will release it, sorry. I have some first working versions, but I am constantly improving the model accuracy, trying to get close to state of the art.

First off - amazing work on this ;)
is it possible to play around with your current implementation? do you have it in a branch that we can access?

[justadudewhohacks]

Age estimation and gender prediction is now implemented.

[examityharikrishna]

That's great news!

[thirukumars]

script.js:26 Uncaught (in promise) TypeError: faceapi.detectAllFaces(...).withFaceLandmarks(...).withFaceExpressions(...).withAgeGender is not a function

I got this error message while running,please help me out

[justadudewhohacks]

it should be withAgeAndGender and not withAgeGender

[thirukumars]

thank you and for draw

faceapi.draw.drawAgeAndGender is not a function

[thirukumars]

hello where do i found the code for recognizing two image without node and using javascript

[ismaildkc]

@thirukumars hello, i'm getting same error, "faceapi.draw.drawAgeAndGender is not a function"
did you solve that?
