Simple Gesture Recognition To Create Virtual Mouse | using OpenCV and Python (Tutorial) Part 1

bro Can you help me please?????

Hello @Codacus, really great tutorials, thank you!

Comparing your code described in the video with the one you launched at the beginning as a demo, I noticed a difference, in particular you replaced:

if abs((((w * h) - (openW * openH)) * 100) / (w * h)) < 30:

with something like:

if (x >= openX) and (y >= openY) and (h <= openH) and (w <= openW) and ...

It's not possible to read the end of the line, but I wonder if that version optimizes the use of the percentage threshold you adopted in your tutorial.

I saw that you also changed the smoothness of the mouse movement by multiplying by a value "c = 0.3" defined at the beginning, instead of dividing by "DampingFactor" and I wonder if this also improves the performance.

Together with the parameter "c = 0.3", you have also defined another "l = .3", which I did not understand where you used it in your initial demo, compared to the one elaborated in the tutorial.

I was wondering if you could share any optimizations here, and how to implement the double click too, with another video!

Thank you so much! Great channel! Best regards

ye error yaara hai

👏👏👏👏

What algorithm did u used can you please tell me. I really like this project

@Codacus sir ...... what kind of change in the windows to perfectly run the program....?

sir i am run this program in my pc(windows), but it gets error and camera is not responding ....plz help...

What is the license of the code? Can I make a tutorial on it?

Why does it keep aborting command

After some conversions of some bugs like float to int, still this is not working , the camera stops responding.

Can you do this for eyes movement?

so cool man

bro this dont working now

You are so good human :)

Which operating system do you use

I'm facing problem to install wxpython on windows10 please help me..

The camera frame is freezed whenever the color of the given object is detected whenever i tried to move the cursor

WOW, this is an amazing tutorial. l Liked and Subscribed.

Website is not working.
Please help me to get the source code.

Cv2.line gives me error

Integer argument expected ,got float

will the same code work on windows 7 ? please reply asap,Thank you!

hey it comes as "cam not responding", once i show a green square/obj the image freezes and doesnt respond , any1 have a solution for this?

Hi! This is really good but how do you change the colour of the thing on your fingers? I'm not very good at python

@Codacus the frame is not responding and freezes

bro you are awesome man

Superr video , Good idea ,Good presentation
Thanks Buddy....

double click ???

nice work man .amazing

how to fix float expected at most 1 arguments, got 2

Thanks a lot, buddy. Excellent video.

Does the double click work?

My cam keeps crashing when smth green gets in range of the webcam. How can I fix it?

You use a special sensor or just a HD camera?

please give me your no .....
about hand gesture project bcoz they cannot capture object in windows

It seems I am going to infinite loop due to the pass statement. Any way to get around it?

Will your code work on Linux too? Because Mavis actually Linux based too.. I need to make this work on raspbian os on raspberry Pi
