Facial Keypoint Detection

Project Overview

In this project, We'll create deep learning architectures to build a facial keypoint detection system. Facial keypoints include points around the eyes, nose, and mouth on a face and are used in many applications. These applications include: facial tracking, facial pose recognition, facial filters, and emotion recognition. Your completed code should be able to look at any image, detect faces, and predict the locations of facial keypoints on each face; examples of these keypoints are displayed below.

Facial Keypoint Detection

The project will be broken up into a few main parts in four Python notebooks:

Notebook 1 : Loading and Visualizing the Facial Keypoint Data

Notebook 2 : Defining and Training a Convolutional Neural Network (CNN) to Predict Facial Keypoints

Notebook 3 : Facial Keypoint Detection Using Haar Cascades and your Trained CNN

Notebook 4 : Fun Filters and Keypoint Uses

Project Instructions

Local Environment Instructions

  1. Clone the repository, and navigate to the downloaded folder. This may take a minute or two to clone due to the included image data.
git clone https://github.com/udacity/P1_Facial_Keypoints.git
cd P1_Facial_Keypoints

  1. Create (and activate) a new environment, named cv-nd with Python 3.6. If prompted to proceed with the install (Proceed [y]/n) type y.

    • Linux or Mac:
    conda create -n cv-nd python=3.6
source activate cv-nd
    • Windows:
    conda create --name cv-nd python=3.6
activate cv-nd

    At this point your command line should look something like: (cv-nd) <User>:P1_Facial_Keypoints <user>$. The (cv-nd) indicates that your environment has been activated, and you can proceed with further package installations.

  2. Install PyTorch and torchvision; this should install the latest version of PyTorch.

    • Linux or Mac:
    conda install pytorch torchvision -c pytorch
    • Windows:
    conda install pytorch-cpu -c pytorch
pip install torchvision

  3. Install a few required pip packages, which are specified in the requirements text file (including OpenCV).

pip install -r requirements.txt

Data

All of the data we'll need to train a neural network is in the P1_Facial_Keypoints repo, in the subdirectory data. In this folder are training and tests set of image/keypoint data, and their respective csv files.

Notebooks

  1. Navigate back to the repo. (Also, your source environment should still be activated at this point.)
cd
cd P1_Facial_Keypoints
  1. Open the directory of notebooks, using the below command. You'll see all of the project files appear in your local environment; open the first notebook and follow the instructions.
jupyter notebook
  1. Once you open any of the project notebooks, make sure you are in the correct cv-nd environment by clicking Kernel > Change Kernel > cv-nd.
