@UttamDwivedi - sorry, but I've just seen your message. If it's still relevant, please mail me at [email protected] and I'll try to help.

@darshanime, indeed there is a problem with a newer implementation of Caffe's io.py. We reported it in the project page: http://www.openu.ac.il/home/hassner/projects/cnn_agegender/

@berak, nice to see that CNN finally made it into OpenCV! I'll try to create a demo of our age/gender nets.

Gil.

@gil , which part is your traing data at http://www.cslab.openu.ac.il/download/AdienceBenchmarkOfUnfilteredFacesForGenderAndAgeClassification/

I find there are some image with age None, and some image don't have gender label. Did you use them for training? Because I want to use your dataset and compare to your result.
Thank you.

@kli-nlpr , I used only the labelled images. I can send you the train/val.txt to create the lmdb for training.

Gil

Hi, @gil, can you send the train/val.txt to me?
My email is [email protected]
Thank you very much

@kli-nlpr, sorry for the late response.

I've added a new git repository for creating the train/val.txt files:

Hi,

I am using the gender detection model in Torch and in Caffe for detection from live camera.

Running the code on CPU and keeping the same models file, I am getting different prediction times.
For Caffe, it is ~1.30 seconds per frame.
For Torch, it is ~0.45 seconds per frame.

What could be the possible reason for the time difference? Is Torch faster than Caffe?

@nitish11, like I commented in the repository , I don't have any experience in Torch, so I really can't tell which is faster.

Hi Levi,

Levi I have some doubts about the network architecture used for the genre classification training:

• Its current architecture identifies the "type" layer by capital letters (eg, CONVOLUTION.), Because you can not conduct training for replacing CONVOLUTION by "Convolution"; DATA by "Data"?

Hi @engesilva,

I think you might need to replace ALL CAPITALS with lowercase letters, depending on the version of Caffe you are using.

@GilLevi The dropbox links are not working. Hitting them shows file not found.

Hi @akashjobanputra, thank you for your interest in our work. I updated the links, they are now working.

Hi @GilLevi,

I've tested your Caffe models in the OpenCV DNN module on a live camera preview, and it's taking 1.6-1.7 seconds to process each frame. Are there any possible further optimizations I can use on the model, without sacrificing accuracy or with a minimum accuracy tradeoff, to make it faster? Because I've gotten another model that could do it in 11 ms (though with very low accuracy - most female faces are guessed male) that was only 2.5 MB in size (maybe trained with 510 images only).

Hi @Gensoukyou1337,

The easiest thing to consider is running on GPU and subsampling so you won't run on every single frame, but run the model on every X frames.

Aside from that, you can train a new model which is smaller and faster, but that would require a lot more work.

Best,
Gil

Hi @GilLevi,

I wrote a simple sample using OpenCV 3.3.1 dnn module (see snippet below). I'm just a bit confused about the mean.binaryproto utilization. In the OpenCV API there is a mean parameter which, I suppose, plays the same role. I'm currently using:

Mat inputBlob = blobFromImage(img, 1.0f, Size(256, 256), Scalar(104, 117, 123), false);

Note the Scalar(104, 117, 123) which corresponds to the mean values which are subtracted from channels (BGR). Is that correct ?

#include <opencv2/dnn.hpp>

#include <fstream>

using namespace std;

/* Find best class for the blob (i. e. class with maximal probability) */
static void getMaxClass(const Mat &probBlob, int *classId, double *classProb)
{
    Mat probMat = probBlob.reshape(1, 1); //reshape the blob to 1x1000 matrix
    Point classNumber;
    minMaxLoc(probMat, NULL, classProb, NULL, &classNumber);
    *classId = classNumber.x;
}
static std::vector<String> readClassNames(const char *filename = "cnn_age_gender_models_and_data.0.0.2/gender_synset_words.txt")

    std::cout << "Time: " << (double)t.getTimeMilli() / t.getCounter() << " ms (average from " << t.getCounter() << " iterations)" << std::endl;
    return 0;
}

I'm getting this for gender:

Best class: #1 'Female'
Probability: 99.7108%
Time: 17.9049 ms (average from 1 iterations)

And this for age:

Best class: #0 '(0, 2)'
Probability: 96.4613%
Time: 16.2971 ms (average from 10 iterations)

is there any keras or tensorflow implementation of the same?

@fabito, Can you please share the link or the file of gender_synset_words.txt.
Thanks.

How this model support multiple people?

accury is so low

Hi,@GilLevi,Can you sent me a set of images to me?I want to transform the data for training.
my email address is [email protected],thanks, if you like ...you can directly sent me the lmdb

@fabito, amazing!! The model we released assume a mean image, where in more recent implementation you can simply use mean value per image channel. We did not re-train the model this way, so using mean value per channel might hurt performance, but I assume that the difference won't be dramatic.

@koduruhema, the "gender_synset_words" is simply "male, femail".

@bengo12, the model receives a single image which assumes to contain one cropped face. It supports multiple people by applying face detection on the image and running the model on each detected face.

@jianti, you can find the images in the AdienceFaces webpage https://www.openu.ac.il/home/hassner/Adience/data.html

Hi everyone, Can you give me how to train this model? how is flow? Please give an explanation. Thank you.

Hi @binanhiasm,

The code for training is given in my repository: https://github.com/GilLevi/AgeGenderDeepLearning

Hi @GilLevi,

Can you please sent me the output of age-gendernet ,i.e., age_gendernet.caffemodel. this is for my learning purpose.Thanks in advance

How to get additional gender like in place of kid I should get the male kid and female kid and how to save the segmentation results in csv ? @GilLevi

@Akshayz-123, the link the the models in at the top of this page

@Harshapriya123, sounds like you would need to run both age and gender models for that.

Can this be used in a commercial product what is the license?
