OpenCV Cascades: Eye Detection

Open / Closed Eyes

LBP | HAAR | HOG


Eye detection is not a trivial task, especially if you want to perform it on ARM devices. Before using the following cascades read carefully this page to get the best performance and to know the terms of usage.


The eye detection is a common strategy in computer vision to start the face alignment by Homography or by a more sophisticated method such as Active Shape Models (ASM), Active Appearance Models (AAM), Features Regression, etc. Regardless from the preferred method, a good and a stable initialization of the process is mandatory to get a perfect alignment in a small number of iterations. A perfect alignment usually bring to superior performance in face recognition, identification or classification task. With similar cascades it’s also possible to start detecting the blinking phenomenon for the driving security. Below the HD model for the detection of eyes via boosted cascades.

Human eyes, trained with:

  • approx. 9,000 positive samples (randomly sampled)
  • approx 0.7 B of negative sub-regions containing faces and non faces samples (90%-10%)

*NEWS*: since June 2016 vision-ary project joined ARGO Vision, an innovative firm that excels in visual recognition. For info about the cascades, please send a message via contact form here.

  1. Hi, I´m tech researcher, and I´m interenting in compere the performance between LBP and HOG both face as eyes, can you share yours HOG xml? Thanks, and it’s fantastic we found this support, congrats!!

    • Hello Hector,
      thanks for contacting us. Unfortunately at the moment we are not planning to share our HOG cascades. Many companies are using our HAAR/LBP/HOG cascades because they are dramatically better than OpenCV ones, keep in touch if some news about our sharing policy will change.

      Best regards,
      Vision-ary team.

    • Hello Hector,
      our policy has changed. If you still need our cascades please write an email to us.

      • Hi Team,
        Could you please send me the LBP/HOG classifier to detect eye regions with spectacles.This is for my master thesis.Could you please help

        Regards,

    • hello Edward,
      send us an email by the contact form with info about the usage (commercial / academic). We will reply in a while.

  2. Hello,

    Great work you have here, congratulations. I’m an engineering student from Brazil and I wonder if is it possible to use your face and eye lbp cascades on my final paper. I sent a message (at contact page) for you with all the details and I appreciate if you take a look.

    Thank you and continue this great job.
    Best regards.

  3. Hello,thanks for your work,I am using HOG for eye detection for academic usage,can you please send the dataset of eyes to me because I could not find a good one .Thanks in advance

  4. Hi, My name is Mustafa. I’m at Yildiz Technical University departmant of electronic and communication engineering. I’m at fourth class now. Nowadays, I am working on my bachelor thesis. I need to lbp eye detection xml. Could you please share? Thank you 🙂 My e-mail address: myigitsert@gmail.com

    • Dear Büşra,
      sorry for the delay in replying to you, we had some issue with spam filtering. Now the blog is again fully working!

  5. Dear Vision-ary team, I would like to use your LBP xml file for eyes. I need this for some detection algorithms in embedded/mobile systems for my bachelor thesis. Could you please send me this file at gabe.n123 (at) web.de? That would be great and help me a lot. Best regards

  6. Dear Vision-ary team.
    I’m a master student on Federal University of Lavras (UFLA – Brazil) who is creating an app that will estimate driver’s sleepiness. Can you send me your LBP xml file, please? That would be extremily great for me. Very greateful!

  11. Hello,
    I am a Photographer and programmer.I have so many pictures, and I have to remove eye blinked pictures.
    If It’s possible, I want to use your eye cascades .
    Can you send me the eyes xml file? Thank you(^_^)

    Thank you.

    • Hello Takayuki,
      thanks for contacting us!

      Eye cascade can detect the presence of the eyes but if you want to analyze the “amount” of opening of the eye is a little bit more tricky than this.

      Anyway we can share the cascade with you to make some test. Send to us an e-mail (with subject: CASCADE OPENCV) to info|AT|vision-ary.net and we will send you the instructions to download the cascade.

      Regards,
      Vision-ary team!

  12. Hi!
    I’m currently learning about deep learning with opencv.
    Can you please share me your eye cascade XML?, I sent you an email via your contact page.
    Thank you.
