Build a Face Mask Detector in 20 Minutes with Watson and Python
ฝัง

- We’re living in strange times at the moment.
And it seems like wearing masks in public are becoming the norm.
So…maybe you’d like to detect who’s wearing one and possibly who’s not.
This is a perfect problem for deep learning and object detection.
In this video you’ll learn how to use Watson Visual Recognition, Python and OpenCV to build a face mask detector. By the end you’ll have all the code required to deploy your very own face mask detector with Python. In this video you’re detecting face masks but you could also use this to detect a whole bunch of other objects as well!
In this video you’ll learn how to:
1. Capturing Images with OpenCV
2. Visualising detections using Matplotlib
3. Training Custom Object Detection Models with Watson

High Quality content man !! you deserve 1million subs i m sure u r gonna get more than that !! kudos to ur hardwork👍
Oh man, thanks so much @Sumedh Dixit! Appreciate it a million!
Bro,make a video on a guideline or roadmap on how someone become a data scientist. Hope u will take it into consideration. Btw,it was a great video.
Awesome suggestion @Mohammad, I'll put it on the list of non-technical videos I've got coming!
Loving these videos Nicholas!
🤟🤟🤟 hell yeah, thanks @Ken!! Just checked out your channel mad ❤️!!
Bro, It was Awesome...... I madly love what you have done. Expecting more videos on OpenCV in future. All the very best bro.
Thank you so much @venkata sreeram, definitely, plenty more to come👨💻!
Super video amazing clarity and frankness
Thanks so much!
Keep Going Nicholas... Best of Luck 👍
I'm on it 👨💻, thanks so much @46.Akangsha Mukherjee!
IBM Watson™ Visual Recognition is discontinued. Existing instances are supported until 1 December 2021, but as of 7 January 2021, you can't create instances. Any instance that exists on 1 December 2021 will be deleted.
Yah, a bit of a pain but I'm going heaps of open source vids on OD.
Love your content, can you please make a full tutorial on React-Js and React Native from start to Finish? :)
Definitely @Viraj Shah, I’ll add it to the list!
Hello sir!! great video
I am getting an error when running in colab in the line
cv2.imshow('frame', frame)
please help :(
Heya @Mudit, what's the error?
Impressive work! Unfortunately I am only getting version v3 in the lite plan, so I cannot do the last part of the tutorial. Also, I saw that IBM will shut off the server for visual recognition in Dec. 21...
Heya @Jonas, I believe that's still the case 😞 (it wasn't when I released the video unfortunately). I've started putting together an open source set of CV tutorials to help out the YT fam, a little more involved but you get wayyyyy more control: th-cam.com/play/PLgNJO2hghbmhUeJuv7PyVYgzhlgt2TcSr.html
Amazing work man thanks for sharing the knowledge
Anytime!! Thanks so much for tuning in!
Please make more difficult projects with functionalis like, without mask person 's count, take pictures of them, alarm system etc
In associate a service. Visual recognition is missing.
Heya @Arkham unfortunately the service has been deprecated. Try checking this out as an alternative: th-cam.com/video/IOI0o3Cxv9Q/w-d-xo.html
Great vid, btw you write really fast and without mistakes lol.
Hahaha, I speed up the coding in the vids, I also make a sh*t ton of mistakes. I think this was one of my early YT vids where I wanted it to look perfect.
Heyy, silly question here....do you require an external webcam for this?
No silly questions my man! The video uses an integrated MacBook webcam. If you didn’t have an integrated webcam then yep, you would need an external camera. Let me know if you need a hand 🙂
Very nice thing! But im getting this error!

Hey!!!
how did you start capturing the images @ 5:10
didnt understand that
Heya @pahal, it's done with OpenCV. It'll immediately open up an image capture window that you can use to capture images!
Bro how we can add voice alert along with this system??
Yep @Nivethitha! I'll make a note for the real time video, once a detection occurs it can trigger an email alert or play a sound!

Hey Nicholas! I couldn't figure out Visual Recognition thing in Watson Studio.
In Watson Studio :-
Step 1 : Add Project
Step 2: Select Visual Recognition
Step 3: To provision.... click here thing

Please help me out figure how to proceed on adding Visual Studio service (associate)
Thanks already man!!
Heya, it's been deprecated unfortunately. It isn't available anymore, I've got some open-source examples using TFOD on the channel though!
Hello Sir, I am having a problem with my Watson studio, when I choose to create my own image detector the page freezes. So is there any other alternative to Watson studio?
All good! Let's dig into it:
1. Can you try clearing your cache and cookies
2. Do you have a visual recognition service up and associated to Watson Studio
3. The other alternative is to do it via the API but that doesn't have a GUI cloud.ibm.com/docs/visual-recognition?topic=visual-recognition-object-detection-overview

same with me. did you get any solution?
Heya @amal and @Deep Patel, this is normally because your webcam isn't capturing any images. I'd suggest the following:
1. Ensure that your webcam is on and activating
2. If it is and still not capturing, restart your Python Kernel
3. Ensure that the file name and file path are correctly defined
@@NicholasRenotte thanks for the reply . While I was doing this project my camera drivers got uninstalled 😂 and it’s not getting back now even if I restart . Any leads.?
@@deeppatel195 try restarting your kernel, stop Jupyter and kick off everything again?
maybe 3:14 issue
I've been trying to fix my recognition model in watson but every time I train the model then test it out, the detection scores are way off and the boxes appear in the wrong place. I've tried the method you used to capture images with python and I've also tried image sets of people with and without masks from online but the results are still the same, any advice?
Definitely! So there's a few things you can do here:
1. Upload and train your model with more images
2. Use images with a bigger variety, different angles, different lighting, different people
3. Increase your confidence score when predicting, so that you only show the results with the highest likelihood of a result
Sir please make video tutorial face recognition with mask identification
it identify person even he/she had a face mask
Great video, Thanks!

What is the meaning of Watson Studio as a training model
Heya @Aryaman Chatterjee, Watson Studio is the data science platform. You can do a ton of DS and ML stuff from there.
We have seen the content of checking the mask on your Youtubu channel. Can you provide an API that can be used in the unity program? We are going to do a project to check whether to wear a mask. I look forward to your response.
Hey definitely, check this out: github.com/watson-developer-cloud/unity-sdk
Why am I cannot associated with a Watson Visual Recognition service?

Heya @Sid, have you created an image folder for collection?
Heyy@@NicholasRenotte :), Yes I did, but then I couldn't find any images inside the folder("Images/Mask"). All I could find were the IPYNB files(notepad) and the IPYNB checkpoints. (:
