OpenCV Python Tutorial For Beginners 35 - Face Detection using Haar Cascade Classifiers

In this video on OpenCV Python Tutorial For Beginners, we are going to see How we can do Face Detection using Haar Feature based Cascade Classifiers.

By the end of the tutorial, you will be able to build a lane-detection algorithm fuelled entirely by Computer Vision.
OpenCV is an image processing library created by Intel and later supported by Willow Garage and now maintained by Itseez. opencv is available on Mac, Windows, Linux. Works in C, C++, and Python.
it is Open Source and free. opencv is easy to use and install.

Starting with an overview of what the course will be covering, we move on to discussing morphological operations and practically learn how they work on images. We will then learn contrast enhancement using equalization and contrast limiting. Finally we will learn 3 methods to subtract the background from the video and implement them using OpenCV.

At the end of this course, you will have a firm grasp of Computer Vision techniques using OpenCV libraries. This course will be your gateway to the world of data science.

Feel the real power of Python and programming! The course offers you a unique approach of learning how to code by solving real world problems.

thank you very much, saved my life on a project.

[robomanthan]

sir, i am big fan of you, I watched your full series OPEN CV based video but sir please help me, HOW TO MAKE FACEDETECTION APP OR ANY APP BY USING IMAGEPROCESSING ...plz if any know then suggest me .

[bebetobapsio]

thanks for this video
Please, how can we plot the object's trajectory?
How do we extract that trajectory for later use?

[maliktabish]

hi sir your work is amazing. learned alot from you. kindly make a video on how to train a classifier on our own video dataset.

[bit--rock]

your github link of opencv is best github link i saw till date

[bhupallysudhakar]

Hello sir, what is the platform used for code execution sir? please reply ASAP

[yasirkhan]

Can we use Haar Cascade for recognition?

[smgqpzk]

thank you, fellow! you give me a great advice!

I'm facing a problem with face detection. Actually, when I run the program, nothing happens. I can see that the camera indicator is on but nothing on the screen. In case of a given .png photo, when I run the program, nothing happens but just opened a cmd blank screen. Can you help me to fix the problem, please?

[hitmoviesshortclip]

but my ( ) downloading is cancelled automatically why ? and how to fix it

[ahsanfarooq]

iam trying in the different image but the rectangle is not showing on the face

[MERUGUBHAVANI]

Sir what is front end back end for this project?? Please respond

[pavankumar]

I m getting error ::expected ptr cv umat for argument src
Kindly help me

[rameshthamizhselvan]

Thanks for showing your face im a big fan of you

Face also detecting from passport photo and inside phone photo. How to stop thum proxy images

[rijuchowdhury]

when I try to access 2 ccCamera by OpenCV, one camera gets freeze. How to solve it?
the error shows:

(-215: assertion failed) !ssize.empty() in function "cv.resize()"
how I used resize function:

cv2.resize(frame, (0, 0), fx=0.25, fx=0.25)
then finally before imshow(), I multiplied with 4.

[TheKing-ydcf]

why when the script run the photo blocked and said to me python is not responding

[subhranilagasti]

how will i do feature extaction of an object using opencv python

[theengineervlogger]

I have tried various methods to solve it but I failed, please help me to solve

Why blue rectangle because (255, 0, 0) is for red
