What is it?

SimpleCV is an open source framework for building computer vision applications. With it, you get access to several high-powered computer vision libraries such as OpenCV – without having to first learn about bit depths, file formats, color spaces, buffer management, eigenvalues, or matrix versus bitmap storage. This is computer vision made easy.

Getting Started

from SimpleCV import Camera
# Initialize the camera
cam = Camera()
# Loop to continuously get images
while True:
    # Get Image from camera
    img = cam.getImage()
    # Make image black and white
    img = img.binarize()
    # Draw the text "Hello World" on image
    img.drawText("Hello World!")
    # Show the image

This example shows a "Hello World" program that uses SimpleCV. In this example we first connect to a USB web camera. We then capture images from the web cam, apply a binary threshold that turns our image black and white, and then draws some text. The program then prints the results to a display.


This image shows the SimpleCV threshold function. The threshold method sets each pixel in an image to black or white depending on its brightness. Example

In this image we applied the SimpleCV edges method. This method sets edge pixels in the image to white. Example

Keypoints are visually unique areas of an image that are used for a variety of 3D reconstruction and image matching tasks. Finding keypoints in SimpleCV is super easy, just call the Image.findKeypoints method. Example

These are just a small number of things you can do with SimpleCV. If you would like to learn more please refer to our tutorial. There are also many examples included in the SimpleCV directory under the examples folder which can also be downloaded from here.

SimpleCV-JS is the port of SimpleCV to Javascript. Although early in it’s development it is still usable in it’s existing form and can be found at: http://demo.simplecv.org, the code can be found: http://github.com/sightmachine/simplecv-js
