Hi, I'm trying to use blink detection with openCV. I tried using:

  • haarcascade_lefteye_2splits.xml (and haarcascade_righteye_2splits.xml)
  • haarcascade_mcs_lefteye.xml (and haarcascade_mcs_righteye.xml)
  • haarcascade_eye.xml
  • haarcascade_eye_tree_eyeglasses.xml

but all of the above detects opened and closed eyes. any idea or XML files that detects opened OR closed eyes?

Thanks!

When you receive the eye region from haarcascade you can localize the pupil in the eye region. If your input image resolution is low The robust method for pupil localization is the use of k-mean(k=3) for segmentation then use circle hough for localization of pupil. If you don't segment your input image then circle hough is unstable.

Your comment seems interesting. I thought there was no way of getting Hough to be stable, especially with low resolution. Could you point to more detail on this technique? By k-mean, are you referring to the clustering function in http://docs.opencv.org/modules/core/doc/clustering.html#kmeans ?
