Face and Eye Detection from Images using HAAR Cascade Classifier

[@omkarrane5867]

Good and appreciable work sir!!!.someday if possible sir please make a video on how to train HAAR cascade classifier XML files for the detection of a particular(example) object.

[@YassirElayadi]

is there any detailed ressource about Haar-cascade algorithm, I want to implement it from scratch in Python ?

[@subramanyak6187]

Yeah I am also!! Did you find out how to do that?

[@MithileshDSCS]

Hey krish could you please explain what is opencv used for and what are cnn's used for? Arent both for image classification?

[@ishaangupta2830]

why we converted the image to gray?

[@DeepakKumar-uz4xy]

what is the use of 1.3 and 5 in face variable that contain as an argument

[@algorithmsguide5076]

@Krish Naik Can you explain why we are using 1.3 and 5 ? More people having the same question..

[@algorithmsguide5076]

@Deepak 1.3 is scale factor and 5 is min neighbors,.. please look for github repo.. krish explained.

THANK YOU FOR THIS PLAYLIST :)

[@Sagar_Tachtode_777]

your post very valuable knowledge... Thank you!!!!

[@subbareddy7008]

where we get the data set please share the link if u have

[@alinajoseph7025]

Is Haar-cascade only for face?

[@krishnamitabanerjee4351]

Can I detect pipe leakage using Haar Cascade sir?

[@Sagar_Tachtode_777]

What to do i want to detect PAN Card and Crop it ??

[@nanigadupudi880]

Great video bro , but i want to iterate loop and save eye features (pixels) using haarcascade classifier by using this i'm able to detect for one image but i'm not able to iterate loop but it showing no image found , is their any solution please let me know

[@louerleseigneur4532]

Thanks Krish

[@suvigyabhardwaj9714]

hi sir, that eye classifier file is creating ruckus in my system. everytime i run the code the face gets detected but as i press any key or enter key for eye detection the kernel dies, plz help me sir

[@saurabhkatiyar4988]

why is it unable to recognize more than 3 faces in a group picture?

[@ijeffking]

Thank you Krish. Is this the start of the CV paylist that you had mentioned earlier ?

Hey Jeff,please check my playlist I have made a playlist on computer Vision Tutorial

when i am using imread function i get this error but 2/10 times it runs the same code . what the problem ? pic = cv2.imread ("‪C:\\Users\\91920\\Pictures\\pic1.PNG",0) print(type(pic)) output - cv2.imshow("image",pic) cv2.waitKey(0) cv2.destroyAllWindows() output - error: OpenCV(4.3.0) ..\modules\highgui\src\window.cpp:376: error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'cv::imshow'

Nice video

[@priyankanagpal2207]

code returns no face found though image is loaded

[@krishnaik06]

Please try with different images.id the images are not good the face might not get recognized

[@priyankanagpal2207]

@@krishnaik06 it worked by changing values of detectMultiScale according to image.

[@chiragagrawal7104]

this haar cascade is not detecting every faces and eyes
