A classification model in Machine Learning capable of recognizing human facial emotions

Emotion-Recognition

This project creates a classification model in Machine Learning capable of recognizing human facial emotions.

Getting Started

This project uses the CK+ dataset containing 8 classes of facial expressions encoded as {0=neutral, 1=anger, 2=contempt, 3=disgust, 4=fear, 5=happy, 6=sadness, 7=surprise}.

Prerequisites

1. CK+ dataset - The dataset used
2. Python 2.7
3. OpenCV 3

Installing

Clone the repository

git clone 'https://github.com/jahin07/Emotion-Recognition.git'

Download the CK+ dataset

Install OpenCV 3

conda install -c menpo opencv3=3.2.0

Running the code

To run the code

python dataset_org.py
python extract_faces.py
python classi.py

How to get the dataset?

I'm a noob! how do you get those datasets? I got the email but not sure which to download?
