Face Detection from IronPython

Note: This example is based on Emgu CV 2.2.0.0

Assume that you have followed everything from Setting up Emgu CV and IronPython. This example is going to show you how to do face detection from IronPython.

First copy the lena.jpg file from OpenCV sample directory to the IronPython folder. Then copy the haarcascade_frontalface_alt_tree.xml file to the IronPython folder as well. Then follow the steps below:

• Create the detector by calling

detector = HaarCascade("haarcascade_frontalface_alt_tree.xml")

• Read the image

image = Image[Gray, Byte]("lena.jpg")

• Detect the objects

objectsDetected = image.DetectHaarCascade(detector)[0]

• Draw the objects

for obj in objectsDetected: image.Draw(obj.rect, Gray(255), 1)

• Display the image

ImageViewer.Show(image)
