Smile Detection

I created this smile/neutral CNN while I was bored during COVID-19 isolation to practice my ML skills. NOTE: It can only detect neutral and smile faces, not intended to detect frowning, laughing, etc...

Demo

Install Dependencies

1. Install Python.
2. Run python3 -m pip install -r requirements.txt inside the smile-detection/ directory.

Train Model (Optional)

NOTE: By default, this GitHub repository comes with a pre-trained model. Training a new model will take a while to run. Please be patient.

1. Open smile-detection/Train.ipynb with Jupyter Notebook.
2. In Jupyter Notebook, click: Cell -> Run All.
3. The model data will be written inside the smile-detection/ directory as smile.model/.

How to Run

1. Run python3 main.py inside the smile-detection/ directory.

Data

The data can be found inside smile-detection/data.csv, where each image is represented as an Numpy array for simplicty. One can iterate through each image and read the numpy array as an image.
