Re: facedetect.c

You have to go to commandline ! 
Go to start button, open a window and type the following in one line:
  --cascade="c:\program 
files\opencv\data\haarcascades\haarcascade_frontalface_default.xml" "c:\program 
files\opencv\samples\c\lena.jpg"
   
  This assumes you have installed opencv in c:\program files\ directory.
   
  Also refer:

  Hope it helps.

  Read the Cegparamesh post, it explains it very well.
The cascade i'm taking about is the file 
"haarcascade_frontalface_default.xml", and it contains the 
informationabout the face's features.
You specify the path of the cascade when you run the program.
For example, whem you run the program like this:
facedetect --cascade="haarcascade_frontalface_default.xml"

You tell to the program that you want to detect objects with the 
features presents in the haarcascade_frontalface_default.xml file (in 
this case frontal faces). Note that the file must be in the same 
directory of the program.
