# hand_ai
### A program which can be implemented in online classes, to detect when a student is raising their hand.
# How it was made:
### Summary:
This AI model was made in https://teachablemachine.withgoogle.com/ and then it was exported
into a .h5 file and then using [CV2](https://pypi.org/project/opencv-python/) it takes a photo
using your webcam. It saves it and then analyses it, prints what it thinks it is and deletes the photo.
### AI specifications:
**V1.00 has been trained on:**
50 Epochs
Batch size : 16
Learning rate : 0.001
**V1.50 has been trained on:**
100 Epochs (for better performance)
Batch size : 16
Learning rate : 0.001
### Libraries:
tensorflow
Pillow
numpy
opencv-python
# Credit
If you want to use this (for your own program not just for having a look at it or running it) for something, open a issue describing what you want to use it for and I will review it.
# Installation
Install all the needed packages by using
```
pip install requiremens.txt
```
in the folder in which requirements.txt is located in.
# Usage
(It takes some time to load and initialize and this has been trained on me so it may not work for you)
Try to have a plain white background and a lightly lit place.
# Troubleshooting
If you get a error like this:
```
cv2.imwrite("cv.jpg", image)
cv2.error: OpenCV(4.3.0) C:\opencv\modules\imgcodecs\src\loadsave.cpp:738: error: (-215:Assertion failed) !_img.empty() in function 'cv::imwrite'
```
Try running the program a few more times, and if that **doesn't work** open a issue with a bug label.
# Why isn't this in my_python_scripts?
I thought that this is a little bigger, and
its not really a script and it's a thing on it's own, so I thought it deserves a repository of it's own.
# I dont have Python !
There's a easier way to view the Model than python, you can also have a look at this link :

Thanks for having a look at this,
