Hi, While running the code on google colab it gives me the below error: OpenCV(4.1.2) /io/opencv/modules/imgproc/src/color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cvtColor' The error only shows up while running the VideoCapture piece of code. Can some one help me resolve.

I am facing the same error

[@RahulKumar-dy4gr]

plz check the last two line i.e. .release() and .destroyallwindows() should be in while loop not in if loop...check and remove all the spaces in the begining of these two line. now code is running perfectly in my case

[@Anonymous-rq2tf]

Amazing, very helpful

[@satyamm9901]

It is an amazing explaination, I find the modi.jpg more hilarious 😂

Subscribed 🤗👍🏼 Hope to learn a lot from you Sir 🙏💐

Thanks Krish

[@surajgupta1515]

what is the difference between detection using yolo and detection using har cascade

[@anandacharya9919]

Superb sir

[@johnjayveec.alindayo9278]

Bro, its possible to put some temperature detection?

[@rohitmittal3632]

great video sir but i am not able to open the code files on the github it is showing some error...i have forked them also but nothing helped and also not able to clone them.

[@pmsanthosh]

Can u differentiate two persons using facial recognition so that if i show his image it should recognise him

[@surujkalita0001]

Thanks ✌️

[@pmsanthosh]

Sir can u do a project like attendance monitoring using facial recognition

[@anishamamgain2018]

What is the need for cropping that particular frame?

[@kunalverma3009]

Cropping the image helps in cutting down the useful data and resizing the size, thus saving storage

[@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

[@JoyBoy-lq]

Sir , is it possible without opencv library?

[@forever-fz1hk]

Sir my Jupiter notebook always takes a lonnnnng time to execute it..How could you execute them so fast...Plzzzz help sir..plzzzz

What's 1.3,5 in detectMultiScale function 5 is neighborhood but whats 1.3 means?

[@iloveanimals123-q7n]

Scale of reduction of video

[@shakyamunghate8382]

Is anyone getting the following error after running the face and eyes detection from video stream? OpenCV(3.4.1) C:\Miniconda3\conda-bld\opencv-suite_1533128839831\work\modules\highgui\src\window.cpp:356: error: (-215) size.width>0 && size.height>0 in function cv::imshow

[@srikarkoneru5894]

update opencv

[@gatsbyacharya3441]

Too much surficial no, much of explanation on any function or values such as rejectLevel, levelWeights.
