Project: Build a Traffic Sign Recognition Program

This is a Work In Progress

Install

This project requires Python 3.5 and the following Python libraries installed:

• Juypyter
• NumPy
• SciPy
• scikit-learn
• TensorFlow

In addition to the above, for those optionally seeking to use image processing software, you may need one of the following:

• PyGame
  • Helpful links for installing PyGame:
  • Getting Started
  • PyGame Information
  • Google Group
  • PyGame subreddit
• OpenCV

For those optionally seeking to deploy an Android application:

• Android SDK & NDK (see this README)

If you do not have Python installed yet, it is highly recommended that you install the Anaconda distribution of Python, which already has the above packages and more included. Make sure that you select the Python 3.5 installer and not the Python 2.x installer. pygame and OpenCV can then be installed using one of the following commands:

Run this command at the terminal prompt to install OpenCV:

opencv
conda install -c https://conda.anaconda.org/menpo opencv3

Run this command at the terminal prompt to install PyGame:

PyGame:
Mac: conda install -c https://conda.anaconda.org/quasiben pygame Windows: conda install -c https://conda.anaconda.org/tlatorre pygame Linux: conda install -c https://conda.anaconda.org/prkrekel pygame

Code

A template notebook is provided as Traffic_Signs_Recognition.ipynb. While no code is included in the notebook, you will be required to use the notebook to implement the basic functionality of your project and answer questions about your implementation and results.

Run

In a terminal or command window, navigate to the project directory that contains this README and run the following command:

jupyter notebook Traffic_Signs_Recognition.ipynb

This will open the Jupyter Notebook software and notebook file in your browser.

Data

1. Download the dataset (2 options)
   • You can download the pickled dataset in which we've already resized the images to 32x32 here.
   • (Optional). You could also download the dataset in its original format by following the instructions here. We've included the notebook we used to preprocess the data here.
