Hand detection is a simple idea, but it requires some advanced tools to do it.
In this project we will allow the user to set the area that will be used to determine the color to capture, and then show, over the videocam feed, where the hand is and what signals it is doing.
The available signals are:
- Numbers using the fingers from 0 to 5;
- OK signal;
- Cool/Fixe signal.
To start the project run at root:
python hand_detection.py <optional_param>
-hcan be used to know what the available params are;--leftor-l: Moves the ROI to the left side;--shotor-s: Detects hand in a single shot, a picture, not video;--input=<path>or-i=<path>: Analyses a stored image;
Then the webcam image is shown saying 'Welcome'.
You can then:
- Press
hto go to the color calculator; - Or press
vto go to the hand detection;
Press q at any time to close the project.
In this mode, you will calculate the color of the hand to be detected.
Place your hand in the blue square and then
- Press
vto capture;
If the result pleases you
- Press
any keyto proceed to video hand detection. If it doesn't: - Press
nto return to the color calculator.
In this mode, you will be able to do signs with a single hand that will be analysed by the algorithm.
Check the list of available signs above.
