Detecting faces and eyes through a camera stream

The camera is another source for real-time data. As frames come and go, we can perform powerful analysis using the OpenCV library.

In this recipe, we conduct facial detection through a live camera stream.

Getting ready

Install the OpenCV, SDL, and FTGL libraries for image manipulation and computer vision:

sudo apt-get install libopencv-dev libsdl1.2-dev ftgl-dev

Install an OpenCV library using cabal:

cabal install cv-combinators

How to do it…

Create a new source file, Main.hs, and follow these steps:

  1. Import the relevant libraries:
    import AI.CV.ImageProcessors import qualified AI.CV.OpenCV.CV as CV import qualified Control.Processor as Processor import Control.Processor ((--<)) import AI.CV.OpenCV.Types ...
