Hi @Jeanbverr,
The pretrained_model was trained with the IMDB dataset.
Does it work for webcam images on your environment?
The image size might not be the problem because the image size is also quite different from that in training in demo.py
and somehow it works (at least on my environment).
Is face detection also performed on your modified demo.py code?
from age-gender-estimation.
Hello, thank you for your response!
Yes, it works for webcam images on my environment, but there is a high fluctuation in age estimation (ranging from 20-30-ish)
Yes I have a face detection. My code looks as follows:
`import os

I see.
Are you using TensorFlow backend?
If so, the problem might be simply the accuracy of the model, which I should work on to improve...
from age-gender-estimation.
Yes, TensorFlow as backend.
It surprises me because it's been trained on half a million images.
Thanks so much for the response though.
I saw your project to be the most reliable one, do you know an alternative, perhaps?
from age-gender-estimation.
For gender estimation, the following project is very cool.
https://github.com/oarriaga/face_classification
I don't know the project for age estimation with reproducible codes...
If you find good one, please let me know :P
from age-gender-estimation.
Alright. Thanks for the response, Ill look into it. It looks promising!
