- เผยแพร่เมื่อ 24 มี.ค. 2021
- In this tutorial we will learn Hand Tracking in real-time. We will first write the bare minimum code to run and then learn how to convert it into a module so we don't have to write it again and again for different projects. The best part is we don’t have to configure 100 parameters along with 20 installs to make it run. Within 10 to 15 mins you will have your model working.

For anyone who may be looking at this video recently, it looks as though you may need to add a new parameter to the .Hands method. "model_complexity", otherwise you may get an error. (I was), after maxHands just add 1 as an extra parameter (Unless you need to modify this)
Error resolved after adding model Complexity. Thanks.
can u please explain more cause ive been trying to and nothing is working
@@zachytg4227 add extra parameter in _ _init_ _ put “model_complexity”. Then your problem will be solved. Thank You….
@@zachytg4227 man
@@zachytg4227 same here man
This channel is so underrated!!
I'm sure this channel will hit 1 million within short time if other coders know about it.
I agree :-) !
Thank you for your kind words. Keep Spreading the word and by you help I will be there in no time.
@@murtazasworkshop please update your github, following your video gives me error- cTime = time.time()
fps = 1 / (cTime - pTime)
pTime = cTime
this gives me an error saying pTime is not defined
you need to set pTime to 0 for the purpose of initialization:
pTime = 0
hope this solves your error
joke of the day lol..
Brilliant! Thank you so much for sharing this topic. The way you explain this topic is very professional and accessible. Keep up your good work!
Not many people do such video... That too with so much detail and explanation.. You have my subscription 👍🏻
amazing tutorial brother!!! OMG from start to finish with detailed explination!!
You're AMAZING brother!! plz continue sharing with us more amazing projects and videos like that all the time!
Best ever explanation. Specially while explaining the parameters and not simply writing them out.
Great pedagogy! Instructive and helpful. Thank you Murtaza!
Thank you so much for this wonderful project!! Please keep on posting such content, you are really talented! :D

bro i have learned a lot of great things from this video, thankyou so much brother, pls keep uploading such kinds of videos
Awesome video as always. Love this channel
Seen this channel for the first time. I love it already!
Oh my God. Amazing video!!! You're the best
excellent, practical tutorial! I've subscribed :)
I would be able to follow the tutorial and gets the exact same result as yours. Hats of to you man.
This is the right tutorial I was expecting... Thank you so much👍👍👍👍👍
professional explanation at its peak. thank you so much teacher
you are very talented...keep making more videos...i watched more than 10 videos in 2 days
You, Mr. Murtaza, you are my idol for doing this kind of videos. Thank you.
Thank you sir. I am working on a small project exactly on this. Your tutorial helps a lot.
Glad it helped
Wow . I`m really appreciated for you to upload these wonderful video thx !
Dear Murtaza perfect tutorial. I have found everything I was looking for.
Thanks
Glad to hear that
First part was a great intro 👍
The second "module" was a good idea but please try sticking with python's code conventions.
Thanks and keep making more videos like this!
what don't you like? I'm learning python from these videos as much as I'm learning openCV. I don't want to pick up bad habits. I grew up on C (and still wish every language was C)
What a useful content
Appreciate your work sir
Thank you very much
I really liked this video, thank you!
Excellent explanation and understandable content. Thanks.
Creative and sincere, thank you! I will follow you.
Great tutorial!! Thank you!!
I from Brazilian and a start learning Lange progamation on 2021 and I love It. Thanks
You're amazing my man!
Absolutely love your videos, cannot have enough of them. I am working on my project and your tutorial is essential for me. A BIG THANK YOU
I'm a beginer and your tutorials are greats and so explicite.
Thank's a lot.
Glad you like them!
@@murtazasworkshop HELP ! .....not able to install mediapipe ERROR: Could not find a version that satisfies the requirement mediapipe
ERROR: No matching distribution found for mediapipe
@@theryze. I am also using 3.7 ..... already checked.
Sir, it would be highly beneficial, if you explain the image stacking function you personally made, in the "open cv in 3 hrs" video.
really very nice and amazing tutorial 😍❤💕
For people getting errors from module and not running, you need to add 1 more parameter to self.mpHands.Hands to fix the issue. It changed with new framework in last update
in init add complexity = 0 parameter (if you want better detection make = 1)
add under other self parameters
self.complexity = complexity
lastly
self.hands = self.mpHands.Hands(self.mode, self.maxHands, self.complexity, self.detectionCon, self.trackCon)
Thanks so much, it works
@@jazztyanatandroid4909 bro can you please share the file link here its not working
@@manishkumar-vz6bw There's no any link bro, you just need to add the code like mentioned above
Thank you, it works
You're a fantastic genius!
I have watched the whole playlist, Kepp up the Good work sir Thank you so much
Really man great job, and thanks a lot for this enthralling tutorial
You’re welcome
@@murtazasworkshopI have error in hand tracking module
This tutorial was really helpful, can u do one for stereoscopic cameras as well.
Excellent content. Thanks for sharing
Great video!

Thanks for sharing your work.
I don't know about opencv Library but i could understand everything. Wow how you are good at teaching ❤❤
Awesome🔥
Thanks Hassan
u r awesome dude!!!
Hello, love the channel from Kenya, quick question though....at 9:40 when testing if the image is being processed, why didn't you pass variable results into cv2.imshow() function instead of variable img???
Nice video, thanks :)
Fantastic tutorial!! Do you happen to know why the main function is executed on one hand only?
Excellent video, very well explained
Glad you liked it
very interesting and useful, it is also quite fast.
Greeeeat. It works.
Greate video, helped me a lot.
I am trying to crop the hand after detecting it ( if one hand crop it if 2 hands crop both hands as one image) any idea how to do this?
Very nice tutorial
Thank You bro!😊
This blowed my mind, Absolutely stunning!! Thanks lot sir for sharing your knowledge.
Hi, amazing project, and that about capture from more than one cameras for more beatiful results?
Can we save inputs for gestures like I can command python to do something when my index finger is up?
Absolute Legend!
Very nice tutorial .What is the use of Z coordinates that appear in each point ?
Thank you for the good video!
I have a question sir
How can we enhance the detecting accuracy of the fingertip??
Most of the times it finds the fingertip well, but sometimes it doesn't
I would appreciate if you tell me the solutions
Really truly top video !
I wonder how to use it as a Leap motion alternative.
Hassan you're a killer.
;)
Put the camera upside down on a table, and you get a cheap leap motion controller 😂
thank you so much! I've been trying to make it to where I could memify my webcam by making it so that i could teach a very simple model the substitution naruto jutsu and make it so when i did the hand signs it would make me dissapear from camera. Thank you so much
Lol
thanks for this video
great video
Thanks much Murtaza...thinking about making a Magic Mirror and adding all this automation...i guess you should be able to select stuff on the screen with gestures ?
Cool stuff
if any one is getting error in detectionCon then change its value from 0.75 to 1, it will work
thank you very much!
Welcome!
thank you so much
Do you get higher framerates when you put the I/O operations on other threads?
It's amazing 🤟
thank you teacher :D
gj! do more on C++
For those who are getting error on inits in module creation....add model_complexity to the parameters and the error will be solved
Thank u
@@dreamwork69 Bro Code Please
Great !!!!
What is the algorithm or model that you use to extract the marker point of finger?
brother thank you soo much with your help i am able to use opencv and hand gesture like a pro thank you soo much bro you will hit 10 million till 2023 i am sure (not writing so i can get a heart my heart voice say this about the chanell
Enjoying this tutorial. For some reason, my version of hands.py has a fifth parameter called "model_complexity" after "max_num_hands". I had to insert that into the class handDetector and in the self.hands definition.
thankyou this helped!❤️
that took me a hot minute to figure out. I'm here to figure out how to mirror the whole thing now so my display matches my gestures. I figured that answer must be in the comments somewhere.
that helped me with my error thanks
Hey, great video. I'm using this tutorial to figure out how to move the cursor using finger tracking. Right now I'm using the index finger to move the cursor and it works fine, I'm using pywin32 module to set the cursor using the index finger's tip landmark. One thing I'm not being able to figure out is how do I manipulate the sensitivity of the cursor. I don't want to move my finger across the whole screen to move the cursor from one edge to the other. This is how I set the cursor: landmark ratio (for example 0.5 if at middle of screen) multiplied by 1920 (width of my screen). I feel like I'm missing something really obvious and simple but after a few hours of trying to manipulate the sensitivity, I thought perhaps you have an idea about how to achieve this.
If you still haven't found something I think this may help.
Find an optimal constant and multiply the cursor distance traveled with your finger distance traveled that may solve the problem
Optimal_constant_x = screen_resolution_x/cam_resolution_x
Same for "y" also
Thank you
Thanks to all for pointing out the 'model_complexity' issue. I added it to the method __init__ and was able to get it to work now.
I added modelcomplexity in __init__ but still not working for me
@@belcamara4874 oh sorry, for init it's double under. Like this "__init__" . Not single _init_. For some reason TH-cam isn't showing the first underscore. So two underscores in front and back..... Now it shows... Hope you understood.
awsome!
how about using this to teach kids typewriting skils.
example
if you type the q with your index it does not print the character
but complain that you mist use your pinkie
FYI, I found someone who kindly packaged this for jetson nano and raspberry pi. I get a couple of errors, but it seems to work.
I just got to the point of the video where we draw the lines to connect the landmarks, and it seems to be working perfectly.
Thanks a lot for the lessons!
Great share your results on the Discord Channel
@@murtazasworkshop
Sure, I will get around to signing up soon.
you might have saved my graduation project damn
can you make a video about sign language detection..
before 1 day looking for a app that work, finally i found
Do you know anyways of getting it to calculate the distance between the camera and one of the id points?
great really
So instead of webcams, what would you put for programs that output video/stream such as ps4 remote play?.
It’s really good
You are pro mam 🔥🔥🔥🔥🔥
Could you detect gesture reconition using mediapipe?
Your the MAN!!!!!
AMAZING!!!!!!!!!!!!!!!!!!!!!!!!
Do you have anything for C++
amazing................
Hi , Thanks, How can I detect if it is left or right hand ?
Cool, I will try this out tonight.
Nevermind, mediapipe is too complicated to get working in python on the jetson nano.
Lol
