Hand Tracking 30 FPS using CPU | OpenCV Python (2021) | Computer Vision

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.

@@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

[@sivakrishna1682]

you need to set pTime to 0 for the purpose of initialization: pTime = 0 hope this solves your error

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)

Great pedagogy! Instructive and helpful. Thank you Murtaza!

[@gorkemkacakgil7141]

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)

Fantastic tutorial!! Do you happen to know why the main function is executed on one hand only?

[@phee3D]

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.

[@rehankhan456]

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

[@averno6174]

Dear friend, as allways amazing. Now a days I'm working around a sign languaje interpreter and I was guessing how to face it; I think this solution suits perfectly my needs!!!!!!! and again you did it for free!!!!! Now I have landmarks and tracking info I think I can compare with saved ones, create a dictionary and just translate into speech. The inverse is just about speech recognition an show appropiate presaved image or sequence. I'm afraid this google library won't be royalty free for use, even in non commercial apps, is it? I think something like a sign languaje interpreter should be in every government administration, office, transport and commerce for free, but unfortunatelly Administrations don't seem to be interested on it. So, thanks a lot, see you on next video and best regards.
