Make computers see with SimpleCV, the Open Source Framework for Computer Vision
SimpleCV is a framework for Open Source Machine Vision, using OpenCV and the Python programming language. It provides a concise, readable interface for cameras, image manipulation, feature extraction, and format conversion. Our mission is to give casual users a comprehensive interface for basic machine vision functions and an elegant programming interface for advanced users.
We like SimpleCV because:
- Even beginning programmers can write simple machine vision tests
- Cameras, video files, images, and video streams are all interoperable
- Information on image features can be extracted, sorted and filtered easily
- Manipulations are fast, with easy to remember names
- Linear algebra is strictly optional
Here is the simplecv “hello world”:
import SimpleCV camera = SimpleCV.Camera() image = camera.getImage() image.show()
The easiest way to install SimpleCV is with the packages for your distribution (Windows, Mac, Linux) included on the website (http://www.simplecv.org). Although it is tested on many platforms there maybe scenarios where it just won’t work with the package installer. Below is instructions on how to install, if you have problems please see the troubleshooting section at the end of this README file.
This is the recommended way of installing SimpleCV as you can be sure the environment will be setup the same exact way as it’s suppose to be on your machine.
WARNING: Using docker does not allow the webcam to work, it also doesn’t work with Image.show(), so essentially requires you to use simplecv within an IPython notebook.
The first step is to install docker on your machine if you have not, this should work for Windows, Mac, and Linux, please follow instructions at: https://docs.docker.com/installation/
Once docker is installed you can run simplecv as easy as (may have to run as sudo, depending on OS):
docker pull sightmachine/simplecv
It will probably take a little while to download, but once done just run (may need to run as sudo, depending on OS):
docker run -p 54717:8888 -t -i sightmachine/simplecv
Then just open your web browser and go to:
NOTE: If you are using a Mac or Windows it will be a little different since you will be boot2docker to run. When you run boot2docker up it should show the ip address of the docker service. It could be something like 192.168.59.103, but this will change as it’s random. Once you know that ip you will just go to that IP address with the correct port instead:
You will get a Ipython notebook inteface, start a new notebook and enter the following:
from SimpleCV import * disp = Display(displaytype='notebook') img = Image('simplecv') img.save(disp)
You should now see the simplecv logo and now have a full simplecv environment setup to start playing around.
Install with pip
sudo apt-get install ipython python-opencv python-scipy python-numpy python-pygame python-setuptools python-pip sudo pip install https://github.com/sightmachine/SimpleCV/zipball/develop
Install using clone of SimpleCV repository
sudo apt-get install ipython python-opencv python-scipy python-numpy python-pygame python-setuptools git git clone https://github.com/sightmachine/SimpleCV.git cd SimpleCV/ sudo pip install -r requirements.txt sudo python setup.py install
then just run ‘simplecv’ from the shell.
This is how to install SimpleCV under a python virtual environment virtualenv. This maybe useful in cases where you want to keep your system libraries clean and not install extra libraries. This method has only been tested on Ubuntu 12.04, it maybe possible to port to other operating systems.

Mac OS X (10.6 and above)
General OSX Overview
Note: We originally tried to bundle all Mac dependencies in a superpack. This turned out to be extremely difficult with the many differences between versions of Mac OS. Now, with Mac, you must build from source and we will try and make it as easy as possible. Please report a bug if you have issues.
Explicit (as in every step) instructions compliments of JHawkins
These instructions are geared towards people who are just getting started with python development on OSX. They will walk you through setting up all the tools you need to build SimpleCV from scratch. If you don’t know which instructions you want, you probably want to use these.
Install Xcode via App Store Start Xcode and go to Xcode >> Preferences >> Downloads >> click Install across from Command Line Tools If Terminal is already running, shut it down and reopen it OS X’s permissions on /usr/local are too restrictive and must be changed via:
sudo chown -R `whoami` /usr/local
Install homebrew via Terminal using:
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
Ignore the single warning that instructs you to install Xcode’s CLI tools (you did that already) To verify that homebrew is installed correctly and working, run:
Address any errors before moving on. Remember, Google is your friend. Note: If you run VM’s on my via Parallels and run into multiple warnings related to “osxfuse” thi go to System Preferences >> FUSE for OS X >> Click Remove OSXFUSE. I can add it back later if needed. Once the doctor tells you that you are ‘raring to brew’, run:
Install OpenCV via homebrew by running:
brew tap homebrew/science brew install opencv
Be sure to add the requested line to you ~/.bash_profile:
Source your ~/.bash_profile file so that the changes take effect:
Install Git via homebrew by running:
brew install git
Install SDL dependencies (can anyone clarify this?) via homebrew by running:
brew install sdl sdl_image sdl_mixer sdl_ttf portmidi
Install XQuartz from https://xquartz.macosforge.org Homebrew can’t install smpeg at the time of this writing however there is a workaround:
brew tap homebrew/headonly brew install --HEAD smpeg
If you get a connection refused error, wait a minute and try again. Download PIL:
curl -O -L http://effbot.org/media/downloads/Imaging-1.1.7.tar.gz
In the unpacked folder:
python setup.py build --force sudo python setup.py install
Manually create a few PIL symlinks:
sudo ln -s /usr/local/lib/python2.6/site-packages/cv.so /Library/Python/2.6/site-packages/cv.so sudo ln -s /usr/local/lib/python2.6/site-packages/PIL /Library/Python/2.6/site-packages/PIL sudo ln -s /usr/local/lib/python2.6/site-packages/cv2.so /Library/Python/2.6/site-packages/cv2.so sudo ln -s /usr/local/lib/python2.6/site-packages/cv.py /Library/Python/2.6/site-packages/cv.py
Install PIP by running:
sudo easy_install pip
Install the Scipy Superpack from http://fonnesbeck.github.com/ScipySuperpack/ Install Mercurial via homebrew by running:
brew install mercurial
Install pygame via PIP by running:
sudo pip install hg+http://bitbucket.org/pygame/pygame
Install svgwrite by running:
sudo pip install svgwrite
Note: SimpleCV’s developers made a change (for the better) here that I am including, however everything up to this point is 100% guaranteed to work, because it’s exactly what I did. Keeping true to that, I’ll present both options. We both suggest using the develop branch. Developer’s Instructions Install SimpleCV from the git repo and then run setup.
git clone https://github.com/sightmachine/SimpleCV.git cd SimpleCV/ sudo python setup.py install
JHawkins’ Instructions Install SimpleCV via PIP by running:
sudo pip install https://github.com/sightmachine/SimpleCV/zipball/master
Test by running simplecv in the command line:
If it starts (it should!) be sure to check out:
Lion Take Two
This is the abridged set of the instructions. It assumes you have most of the common OSX developer tools installed like brew and pip. If you don’t know what Brew or Pip are you probably want to use the instructions above. For OSX Lion make sure you install Mercurial (aka hg - brew install hg). There may be errors in pygame associated with not installing X11, if you encounter this problem please submit an issue on github.
Before you begin installing SimpleCV make sure you have the folliwng tools installed.
- Install Xcode https://developer.apple.com/xcode/ and then run the Xcode installer.
- Install homebrew https://github.com/mxcl/homebrew/wiki/installation

If you want a streamlined install which gives you all the dependencies, we recommend using the Windows Superpack, available at http://www.simplecv.org/download/
If you already have Python, OpenCV or SciPy installed and want to keep things the way you like them, follow the directions below
Install Prerequisties if they aren’t already installed on your system:
- Install Python 2.7: http://www.python.org/ftp/python/2.7.3/python-2.7.3.msi
- Install Python Setup Tools for Windows: http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11.win32-py2.7.exe
- Install the SciPy superpack: http://sourceforge.net/projects/scipy/files/scipy/0.9.0rc5/scipy-0.9.0rc5-win32-superpack-python2.7.exe/download
- Install the NumPy superpack: http://sourceforge.net/projects/numpy/files/NumPy/1.6.2/numpy-1.6.2-win32-superpack-python2.7.exe/download
- Install Pygame for windows: http://pygame.org/ftp/pygame-1.9.1.win32-py2.7.msi
Download OpenCV 2.3 Superpack: http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.3.1/OpenCV-2.3.1-win-superpack.exe/download
Run the executable file and when it ask where to extract to use::
(OPTIONAL) Install MinGW for optional files and building openCV from source. Make sure to include C/C++ Compiler and msys package. (http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/)
Once these are installed you need to add Python to your Path, open a command line (start->run->cmd)::
SETX PATH C:/Python27/;C:/Python27/Scripts/;C:/OpenCV2.3/opencv/build/x86/vc10/bin/;%PATH% SETX PYTHONPATH C:/OpenCV2.3/opencv/build/python/2.7/;%PYTHONPATH%
Exit the command line and reopen so it loads the updated python paths, then run::
easy_install pyreadline easy_install PIL easy_install cython easy_install pip pip install ipython pip install https://github.com/sightmachine/SimpleCV/zipball/1.3
###Windows 8 Step 1
http://www.simplecv.org/download => Go to this page and download SimpleCV latest stable version Superpack . It will start downloading a file named SimpleCV-(version).msi . This file will be around 192mb .
After Downloading run the file . It will start an installation window along with a command prompt window. Give yes permission and press next . First it will install python 2.7.3 . Then it will install numpy,scipy,Pygame,openCV and now all the normal installation windows will be closed and still there will be command prompt running . Leave it as such it will download some other file like cython and when it is finished commandpromt will display a success message “SimpleCV installed successfully” “press any button in 10sec or will close automatically ” . Now just press any button or wait for the count down .
This is the final step and here we are confirming our SimpleCV installation. To do this open Python IDLE . Type in any of these two commands :
>>from SimpleCV import * or >>import SimpleCV
If this two commands works fine without any errors our installation was successfull. If some error occurs we should uninstall and restart or check some forums.
NOTE:- If this error is shown: “AttributeError: ‘module’ object has no attribute ‘csgraph_to_masked’ ” . Before this they will be showing list of paths of scipy library . The solution for this is to install latest stable version of scipy for windows . www.scipy.org/Download => we can download latest stable version of scipy for windows here.
SimpleCV Interactive Shell, or how to run SimpleCV
Once you have SimpleCV installed, you can use it in a specialized IPython shell. This pre-loads all the symbols and gives you some extra functions and macros for using SimpleCV.
To run the SimpleCV shell, from the installation directory type:
If for some reason the shell doesn’t start, you can always do so manually by running:
python -c "import SimpleCV.Shell;SimpleCV.Shell.main()"
To run SimpleCV within an ipython notebook (ipython-notebooks are required to be installed):
to install ipython notebooks run the following:
sudo pip install tornado
sudo pip install pyzmq

SimpleCV on Mobile (Android)
SimpleCV can in fact be used on a mobile device. Although the processing requires a server to be setup that runs SimpleCV our 2012 Google Summer of Code student had built, we have forked the project and instructions on how to set it up and run it can be found at: https://github.com/sightmachine/simplecv-mobile-camera
You can always head over to the SimpleCV help forums to ask questions: (SimpleCV Help Forums) - http://help.simplecv.org
Troubleshooting installation problems.
If for some reason the standard installation methods do not work you may have to manually install some or all of the dependencies required by SimpleCV.
The installation instructions below should explain more on how to install. They can also be installed manually.
- Python 2.6+ (http://www.python.org)
- SciPy (http://www.scipy.org)
- NumPy (http://numpy.scipy.org)
- Pygame (http://www.pygame.org)
- OpenCV 2.3+ (http://opencv.org)
- IPython 10+ (http://ipython.org)
- PIL 1.1.7+ (http://www.pythonware.com/products/pil/)
These libraries are NOT required to run or use SimpleCV but are needed for some of the examples if they are ran. Some of these may be included in your systems software manager or app store.
